2-2 Dimensions

Reasons for rejection

Mandatory equipment

1. A forklift exceeds the dimension requirements set out in Table 2-2-1 and is not fitted with the appropriate hazard warning equipment set out in Table 2-2-2.

2. A required revolving amber beacon cannot be activated and deactivated.

Note 1 Definitions

The rear axis

a) in relation to a vehicle with only one non-steering axle, means that axle,

b) in relation to a vehicle with a non-steering axle set of two axles, means:

i. midway between those axles, if each axle has an equal number of tyres on it, or

ii. two-thirds of the distance from the lesser-tyred axle towards the greater-tyred axle, if one axle has twice as many tyres on it as the other axle

c) in relation to a vehicle with a non-steering tri-axle set or a non-steering quad-axle set, or an overdimension vehicle with more than three axles, means midway between the extreme axles of the set

d) in relation to a vehicle whose rear axle set includes one or more steerable axles in conjunction with one or more non-
steering axles, means midway between the extreme non-steering axles of the set.

Front axis means the centre of the foremost axle of a rigid vehicle with motive power.

Wheelbase means the distance from a vehicle’s rear axis to its front axis.
