Doors

Information

This inspection does not apply if no drivers or front passenger's doors were fitted as part of the original design of the vehicle.
A lack of door handles because of original design characteristics or specialist modification is not a reason for rejection provided the door can be latched securely in the dosed position.

Method of Inspection

Open and close the drivers and passengers' doors. Check that each latches securely in the closed position. Check also that front doors can be opened from both inside and outside the vehicle.

Reason for rejection

a. A driver's or any passengers door does not latch securely in the closed position
b. a driver's or front passenger's door cannot be opened from both inside and outside the vehicle from the relevant control in each case.

Note: Reason for rejection 1 b does not apply to:
. goods vehicles modified for the carriage of high value cargoes such as armoured security vehicles
. front passenger doors if the door aperture has been permanently 'filled' as part of a specialised customisation provided that there are no obvious aperture gaps.
