Width of rear protective device:
Difference:
The width of the rear protective device is not less than the width of the
widest rear axle by more than 100mm on either side (total 200mm).
The ground clearance: (must not exceed 550mm over its width)
Securely attached to the vehicle chassis side members:
Vehicle Rear Construction Forms The Rear Protective Device
When the construction of the rear of the vehicle forms the rear under run
protection device, then the ground clearance of the rear part of the vehicle
must not exceed 550mm over a width which is not shorter than that of the
rear axle by more than 100mm on either side (excluding any tyre bulging
close to the ground).

Result (Pass/Fail)

The space for mounting the rear registration plate shall comprise an
even or virtually even rectangular surface with the following
dimensions:
Width 520 or 120mm
Height 120 or 240mm
 The space must allow the mounting of a plate in a position as close to
vertical as is possible by the vehicle structure available.
o < 30º from the vertical if plate is facing upwards.
o < 15º from the vertical if plate is facing downwards.
 The plate shall be visible in the whole space.
46. Tyres (Note - see appendix 2 below)

is fitted with e or E marked tyres (record approval number)


particular axle locations and the intended use of the vehicle.
(see appendix 2 below for indices)
Each tyre fitted must have the same structure (eg bias-belted, crossply or
radial), nominal size and aspect ratio as any other tyre on the same axle
