How to Reduce Oil Dependence Costs

Today, over half of the oil we use is imported (58%), and our dependence will increase as we use up domestic resources.

Most of the world's oil reserves are concentrated in the Middle East, and about two-thirds are controlled by OPEC members.

Oil price shocks and price manipulation by OPEC have cost our economy dearly—about $1.9 trillion from 2004 to 2008—and each major shock was followed by a recession.


Solutions


We may never eliminate our need to import oil, but we can reduce cartel market control and the economic impact of price shocks by reducing our demand.

Congress recently passed legislation to decrease our dependence on oil by increasing corporate average fuel economy (CAFE) standards on new cars and trucks to 35 mpg by model year 2020. This could reduce our petroleum use by 25 billion gallons by 2030.

Ultimately, the solution to this problem lies in technological progress:

* Developing advanced vehicle technologies that use energy more efficiently
* Creating new energy sources that can replace petroleum cleanly and cost-effectively

How Hybrid Electric Cars Work

Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.



Regenerative Braking. The electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.

Electric Motor Drive/Assist. The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. In some vehicles, the motor alone provides power for low-speed driving conditions where internal combustion engines are least efficient.

Automatic Start/Shutoff. Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.

American Automobile Labeling Act (AALA) Reports

The National Highway Traffic Safety Administration (NHTSA) has provided these reports as an aid to consumers considering the purchase of a new vehicle. The charts list information that NHTSA received from vehicle manufacturers about the U.S./Canadian content (by value) of the equipment (parts) used to assemble passenger motor vehicles. The American Automobile Labeling Act (AALA) defines a passenger motor vehicle as a motor vehicle designed to carry not more than 12 persons with a gross vehicle weight rating not greater than 8,500 pounds and includes multipurpose passenger vehicles and light duty trucks. It does not include a motorcycle or a truck not designed primarily to carry its operator or passengers, i.e., a delivery truck. A label with the U.S./Canada content percentage and related additional information must be displayed on these vehicles up to the time of first retail sale.

Each new passenger motor vehicle must be labeled with the following six items of information:

1. The percentage U.S./Canadian equipment (parts) content;

2. The names of any countries other than the U.S. and Canada which individually contribute 15 percent or more of the equipment content, and the percentage content for each such country (a maximum of two countries);

3. The final assembly point by city and state (where appropriate), and country;

4. The country of origin of the engine;

5. The country of origin of the transmission; and

6. A statement which explains that parts content does not include final assembly (except the engine and transmission), distribution, or other non-parts costs.

The percentage U.S./Canada equipment content, as well as content percentages for other countries are calculated on a "carline" basis rather than for each individual vehicle and may be rounded to the nearest 5 percent. The term "carline" refers to a name of a group of vehicles which has a degree of commonality in construction, e.g., body and chassis. Light duty trucks are considered to be different carlines than passenger cars. A carline includes all motor vehicles of a given nameplate.

Vehicle manufacturers must calculate the equipment content percentages for their carlines prior to the beginning of the model year. They estimate the number of vehicles and subgroups of vehicles that will be built within each carline, e.g., the number of base level and high-line models. For each carline, the calculation of U.S./Canadian content percentage also includes:

1. The U.S./Canadian content (by value) of each item of motor vehicle equipment that will be used to assemble the vehicles within the carline;

2. The total value of each equipment item, i.e., the price the manufacturer will pay for it (this information is typically provided by the manufacturer's suppliers); and

3. The total number of each of the equipment items that will be used to assemble the vehicles within the carline during the model year.

When optional equipment is offered for vehicles within the carline, the vehicle manufacturer estimates the installation rates for that equipment. For example, if vehicles are offered with a manual and automatic transmission, the manufacturer will estimate how many vehicles will be built with each transmission.

The label must be placed in a prominent location on each vehicle where it can be read from the exterior of the vehicle with the doors closed. It may be part of the Monroney price information label, part of the fuel economy label, or a separate label.

The tables that follow list information that was submitted to NHTSA by vehicle manufacturers. The tables include what we believe is the most important information that is displayed on the labels, i.e., the percentage of U.S./Canadian content; whether the vehicles within the carline are passenger cars or other vehicle types, e.g., multipurpose passenger vehicles or MPVs; and where they are manufactured, in the U.S./Canada, elsewhere, or in some cases both. A vehicle's type can be found on its certification label located on the driver's door or door jam.

In addition, NHTSA has other information about safety equipment and systems that are standard or optional equipment on new vehicles on the web site www.safercar.gov. Also included on the web site are data from the agency's New Car Assessment Program (NCAP) including the relative frontal and side crash protection in new vehicles as well as a vehicle's likelihood to roll over from a single vehicle crash. Information on vehicles that NHTSA has tested in the NCAP program can be obtained by calling the agency's toll-free Auto Safety Hotline at 888-327-4236.

If you want to review the original submission from the manufacturers or request research done on the Part 583 submissions, please contact the NHTSA Technical Information Services (TIS). The TIS Reading Room (E12-100) is open to the public during the hours of 9:30 A.M. to 4:00 P.M. (Eastern time). Users may visit the Reading Room to perform their own research. TIS staff members are on duty to assist users. Due to security, have the guard call our Reference Desk, (202) 366-2588 for an escort.

Customers unable to visit TIS in person but requiring extensive searches of the collections are requested to put the details of their requirements in writing, authorizing a fee search for which they agree to make payment.

Important Buying Vehicle Tips

Buying a Vehicle

Purchasing a vehicle can be an overwhelming task. There are some things you should do before you arrive at a dealership. Do some research:

  • Determine how much you can afford to finance and spend on a monthly payment.
  • Get a copy of your credit report so you are aware of what creditors will see. A free copy of your credit report is available at www.annualcreditreport.com or you can call toll free: 1-877-322-8228 or for hearing impaired consumers, TDD service at 1-877-730-4104]. Errors or accurate negative information can impact your ability to get credit and/or your finance rate.
  • Don' t spend more than you can afford. It is easy to get carried away.
  • Know how much your trade is worth (if you have one) and know the value of the vehicle you are purchasing. Information can be found in auto buying guides, the Internet, your bank, and other sources.
  • Compare current finance rates being offered by contacting various banks, credit unions or other lenders. Compare bank quotes and dealer quotes and know any limitations on the rate (e.g., only available on late model cars)

Important Buying Tips

  • Check to see if the car comes with a warranty and, if so, what the specific protections are that the dealer or seller will provide. Remember, if you buy a car " as is" and have problems with it, you must pay for any repairs yourself.
  • Ask to have the car inspected by an independent mechanic, or arrange an inspection yourself before you agree to a purchase.
  • Contrary to popular myth, neither state nor federal law gives consumers a right to cancel a car purchase.
  • Make sure you get any promises made by the dealer or seller in writing (for example, to replace a broken tail light). Verbal promises are difficult to enforce.
  • Ask whether or not the dealer or seller offers an extended warranty or service contract. If you decide to purchase a service contract, make sure you understand what it covers and how long it will last.
  • Inquire about any prior damage to the car and its repair history. Don' t automatically accept the seller' s response as accurate.
  • Always test drive the vehicle.

Fuel economy and the Greenhouse Gas Scores

How do I find the greenest vehicle possible?

We have identified the lowest emitting and most fuel efficient vehicles with a "SmartWay" designation. In addition, the best of those are identified as "SmartWay Elite." Look up all SmartWay and SmartWay Elite vehicles from the Home:Basic Search Look up the Greenest Vehicles page. Click on the logos to see more about the SmartWay rating system.

How can I look up a used car?

You can use this Guide to determine the Air Pollution and Greenhouse Gas Scores of any model year 2000 and later car or truck. There are no Air Pollution or Greenhouse Gas Scores for earlier models. However, there are other ways to look at the air pollution (emissions) and greenhouse gas (related to fuel economy) data for older models:

* Emissions: EPA annually posts detailed emission certification test information (actual vehicle test data) in a spreadsheet format at www.epa.gov/otaq/crttst.htm. This data is more technical in nature and may not be useful to the average consumer. Beginning in model year 2004, light-duty vehicles and trucks were required to meet “Tier 2” emission standards. Most vehicles built before 2000 were subject to the less stringent National Low Emission Vehicle (NLEV) or Tier 1 emission standards, and would score between 1 and 3 today. (See the detailed table of emission standards (6 pp, 54k, About PDF) for more information. )


* Fuel Economy: For fuel economy information on cars older than model year 2000, go to the EPA/DOE fuel economy web site at http://www.fueleconomy.gov. This site has fuel economy information for all vehicles going back to 1985.

Why are some vehicles sold only in some parts of the country?

California has emission standards that are similar to but not exactly the same as federal standards. In addition, other states are permitted to adopt the California standards. For the 2008 model year, the following states have adopted the California LEV 2 emission standards: NY, ME, MA, PA, RI, CT, VT. Also, states which border those states may also sell California-certified vehicles. Most manufacturers choose to design a single vehicle type that complies with both California and federal emission standards, thus the vehicles will be available nationwide. However, in some cases, manufacturers will design and certify a vehicle type for sale in California only or the "California states." Information about California's emission standards program can be found at www.arb.ca.gov/msprog/msprog.htm. Exit EPA Disclaimer

Why must I select a state before looking up a vehicle?


Emission requirements for vehicles sold in California and certain states that have adopted California's vehicle emission standards are different from those sold in the rest of the U.S. The law also allows states that border the so-called "California states” to sell California-certified vehicles. As a car shopper, all this makes it very complex to determine where you can purchase the cleanest vehicle that meets your needs. On the previous version of the Guide, after you selected a vehicle, we showed you maps where the vehicle could legally be sold, leaving it up to you to determine if the vehicle was available. In our redesign of the Guide, we now ask that you simply select the state or states where you may be purchasing your vehicle, and the program determines which vehicles you may be able to find in those states, taking some of the guesswork out of your decision. However, please be aware that just because a manufacturer is allowed to offer a vehicle for sale in a certain state does not mean that it must or will offer it for sale there. Sometimes, a manufacturer will certify a vehicle for sale in the entire 50-state region, but only plans to offer it in a limited area. We have no way of knowing these plans, so it's always best to check with your dealer about availability. Information about California's emission standards program can be found at www.arb.ca.gov/msprog/msprog.htm.

Why can't I find some of the biggest trucks, SUVs and vans in this Guide?


Some of the largest vans, pickup trucks, and sport utility vehicles are officially classified as "heavy-duty trucks." Heavy-duty trucks have different emission standards which cannot be easily compared to the standards of the light-duty trucks, and are thus not included in this Guide. They are also exempted from any federal fuel economy requirements. More information about the emission requirements for these and other heavy-duty vehicles can be found at www.epa.gov/otaq/hd-hwy.htm

Alternative Fuels



Alternative fuels are derrived from resources other than petroleum. Some are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel.

To promote alternative fuels, the Federal government offers tax incentives to consumers purchasing qualifying alternative fuel vehicles.



Ethanol is produced domestically from corn and other crops and produces less greenhouse gas emissions than conventional fuels.

Biodiesel is derived from vegetable oils and animal fats. It usually produces less air pollutants than petroleum-based diesel.

Natural gas is a fossil fuel that generates less air pollutants and greenhouse gases.


CNG Logo Propane, also called liquefied petroleum gas (LPG), is a domestically abundant fossil fuel that generates less harmful air pollutants and greenhouse gases.



Hyd
rogen can be produced domestically from fossil fuels (such as coal), nuclear power, or renewable resources, such as hydropower. Fuel cell vehicles powered by pure hydrogen emit no harmful air pollutants.

How to deal with a Car Accident


Right after the accident, you should:
  1. Stop. If you can, move your car to the side of the road or out of the way of oncoming traffic. If you can’t move your car, stay in your car with your seatbelt fastened and wait for help. Warn other drivers with flares and hazard lights.

  2. Help or get help for injured people.

  3. Call 911 or the local police department to report the accident.

  4. Do not say that you caused the accident.

  5. Exchange the following information with the other
    driver(s):
    • name
    • address
    • phone number
    • insurance company
    • insurance policy number
    • driver license number
    • license plate number

  6. Write down:
    • description of the other car(s) – year, make, model, and color
    • exact location of accident
    • how the accident happened
    • phone numbers and addresses of witnesses

  7. Work with the police, but do not admit or accept blame for the accident.

After an accident, you and your parents or guardian should:

  • Call or see your doctor if you have any injuries.

  • Report the accident to your insurance company.

  • Check with your local Department of Motor Vehicles (DMV) to see if you need to report the accident.

  • Contact your insurance company and/or a lawyer if you are sued.

  • Contact a lawyer if you need legal advice or help making a claim or dealing with your insurance company.

Buying a Vehicle on the Internet online

One out of every four cars bought today is found on the Internet. Unfortunately vehicles listed online could have hidden problems such as odometer rollbacks, flood damage or non-working air bags and are sold to unaware consumers. If you are buying a vehicle online take advantage of the following tips.

Do Your Homework


If the vehicle is titled in Florida, you can access “Motor Vehicle Check” on the Department of Highway Safety and Motor Vehicles’ website to see if there are any outstanding liens or the vehicle has been branded as salvage or a flood vehicle. Best of all this service is free.

There are several commercial motor vehicle history reports that can provide useful information about whether the car has been in a crash and was reported to authorities. You can also find out whether the vehicle was ever reported as stolen, salvaged, damaged, or flooded. Records can include mundane activities like title transfers, as well as more significant activities like crashes. When you purchase a report, you’ll be able to see the detail of each record so you can make an informed assessment of the vehicle’s history. Some sites even offer warranty and service information. Be sure to ask the Seller a question if you have any concerns regarding the vehicle history.

Use your discretion. If the price of a vehicle sounds too good too be true, it probably is. Use extra caution or contact the seller to find out what may be contributing to such a low price (like damage or title issues).

If the seller isn't local, determine if you will pick up the vehicle or have it shipped (typically, sellers can help arrange shipping, but buyers usually pay for this service).

Narrow your choices

Several commercial web sites include car reviews, pricing reports and various amounts of information on a variety of vehicles. After setting a price range, you can compare dozens of vehicles online to help narrow your choices.

Get an Inspection

If you are buying from a seller in your area, ask to take the vehicle to a mechanic who you know and trust. If they are not in your area you can schedule a mobile vehicle inspection with a professional mechanic or an auto inspection service that will go to the vehicle. Getting an inspection may be more expensive than a history report, but it could alert you to any possible mechanical or other problems that are not visible online.

Set up a paper trail

Do not wire money to the seller; never use instant money transfer services. If you wire money or use instant money transfer services there is no paper trail indicating that you purchased a vehicle from a particular dealer and all you will have is a transfer number. Using safe payment methods for vehicles protect both the buyer and the seller. If you decide to pay in cash, do so in person. If you decide to pay in person you can either send a check or arrange a bank transfer. If the car does not show up when it is supposed to, you will need to have proof that you paid for the vehicle. Always contact the seller if you have questions about payment.

Learn about the Seller

Learning about the seller is just as important as learning about the vehicle. A Seller should offer a detailed description of the vehicle and respond promptly to any questions you ask. Do not buy the vehicle until you have made successful contact with the seller and all of your questions have been answered to your satisfaction.

If the seller is a motor vehicle dealer in the State of Florida, you can contact the Division of Motor Vehicles at (850) 617-3171 to determine if the dealer is licensed and in good standing.

Get the Deal in writing

Ask the seller to send you a work sheet that indicates whether the vehicle is being sold with a limited warranty or “as is.” Ask that the dealer sign the work sheet so that there will not be any surprise fees when you are ready to sign the paperwork and pay for the vehicle. Please be aware that if the vehicle is being sold “as is” it is being sold in its current condition. In these cases you may want to consider purchasing a limited warranty to protect yourself against any unforeseen problems. The work sheet should include but not be limited to:



* Make of vehicle
* Model of vehicle
* Year of vehicle
* Vehicle identification number (VIN)
* Mileage
* Purchaser
* Seller
* Date of purchase
* Price (including any sales tax, title fees, extra warranties, shipping costs, etc.)



Ensure that you receive the title


Florida law requires that Florida dealers apply for title and registration on behalf of the buyer within 30 days of delivery of the vehicle. The Division of Motor Vehicles licenses and regulates Florida dealers and helps to resolve any disputes concerning motor vehicle sales and warranty work. For assistance and local office addresses and phone numbers or to file a complaint click here or call (850) 617-3171.


If you feel like you have been a victim of fraud

If, in the process of purchasing a vehicle online, you feel you have been a victim of an Internet fraud, you should contact the Internet Crime Complaint Center (IC3), formerly Internet Fraud Complaint Center. You may file a complaint with the IC3 online. If you have questions about internet fraud or what steps to take to file a complaint.


Finally

If you purchase an automobile online from an out-of-state vendor, do not forget to pay the sales tax. The law is different in each state but Florida has very specific rules regarding internet purchases. The “use tax” applies to “items purchased outside Florida, including another country, which are brought or delivered into this state and would have been taxed if purchased in Florida.” If you have questions about the “use tax”.

Car Accident Knowledge

At some point in your life, you will probably be involved in a car accident. It may simply be a bump in the parking lot, or you could end up in a more serious accident where people are injured. In any case, knowing how to react to a car accident will improve the outcome for everyone involved.

You may be wondering, "Why do I need to know what to do if I'm in a car accident?" If you do not follow the proper procedure, your insurance company could refuse to pay your claim. In addition, you could face fines if you do not follow legal procedures. Being aware of the steps to follow will help you when you file police reports and when you file for insurance compensation.

As a precautionary measure, keep first aid supplies and an emergency kit in your car. Flares, a bright orange vest, a cell phone, and a disposable camera are all helpful objects to have in case of an accident.

If you are in a moving vehicle when an accident occurs, immediately and safely pull over to the side of the road, turn off your car, and turn on your hazard lights. Check to see if anyone is hurt. If there is an injured person, do not move them until you take standard first aid measures. Place flares, cones, or triangles alongside the road a few hundred feet before the accident so traffic is aware that there is an accident ahead.

Call 911 and inform them of any injuries. If you are on a freeway and do not have access to a cell phone or telephone, check for a roadside phone that you can use.

Trade information with everyone involved in the accident. Be sure to exchange the following:

• Name, address, phone numbers of all drivers
• Name, address, phone number of all passengers or witnesses
• Driver's license numbers and license plate numbers
•Insurance companies of all drivers involved
• Registered owners of all cars
•Year, model, make, etc. of all cars involved

Do not discuss what happened with anyone else but the police. Do not say that it was your fault, and do not make accusations. These comments may be used against you later. If time and accident conditions allow, take notes about your perception of what happened.

Immediately report the accident to your insurance company, and to the police if there is over $500 in damages (in Washington state-check with your state laws for the dollar amount in your state). You may find that the other driver has filed a report stating that the accident was your fault. If you have or suspect an injury, visit a doctor right away.

Following these simple steps will keep the accident scene as safe as possible, and will help to ensure that no one has to bear unnecessary blame. The next time you are involved in an accident, whether it be a fender-bender or a rollover, don't panic. Now you know the proper procedure for dealing with this type of situation.
