Test the light transmittance level of the windscreen and front side windows

NOTE: This section should be read in conjunction with the equipment manufacturers' instructions.

The light meter may have up to a 5% measuring inaccuracy. A vehicle may be accepted if the readings are up to 5% lower than the minimum light transmittance.

The light transmission requirements do not apply to a tinted or opaque band at the top of the windscreen, provided they are above the arc swept by the windscreen wipers, or 10% of the depth of the windscreen whichever is the greater.
