This inspection applies to all stop lamps fitted.
Vehicles first used before 1 January 1936 are not required to be fitted with a stop lamp.
Stop lamps are not required to be fitted to vehicles used only during the hours of daylight, which are fitted with neither front nor rear position lamps, etc. (See 1.1.A).
Vehicles first used before 1 January 1971 must be fitted with one stop lamp either on or to the offside of the vehicle centre line. If such a vehicle has two lamps fitted, it should be treated as a vehicle first used on or after 1 January 1971.
Vehicles first used on or after 1 January 1971 must be fitted with two obligatory stop lamps.
Additional stop lamps fitted and connected must be tested. Where extra lamps are fitted and there is doubt as to whether they are connected, the benefit of this doubt should be given to the presenter.
On vehicles first used before 1 September 1965 it is acceptable for a stop lamp to be incorporated with a direction indicator lamp.
Tricycle and quadricycle requirements are detailed at Section 9.1.
Apply the service brake and check that the correct number of stop lamps:
are correctly positioned and secure
Note: The precise position of obligatory lamps is not part of the inspection, but check visually that the lamps are at about the same height and the same distance from each side of the vehicle.
are not obscured
are in good condition
Note: An effective proprietary repair (e.g. lens repair tape etc.) must be assessed on its merits, considering security, colour, light output and durability.
emit a steady red light
are not adversely affected by the operation of any other lamp.
A stop lamp:
missing, insecure, obviously incorrectly positioned or does not face to the rear
inoperative or less than 50% of the light sources illuminating
obscured so that less than 50% of the lamp illuminating surface is visible from the rear
not visible from a reasonable distance due to excessive damage, deterioration, or having products on the lens or light source
shows other than a steady red light to the rear when any service brake is applied, or remains on when the service brake is released
adversely affected by the operation of any other lamp, e.g. dual-function lamps on foreign vehicles.
