1.3.1 Brake Testing

As minimum all Group Companies must ensure that ALL vehicles undergo a full and meaningful brake test
in line with local statutory requirements. In order of preference testing methods are:

1. Full roller brake test (on a calibrated rolling road)
2. Road test using a printed report from a decelerometer
3. Road test with manual record from a decelerometer
4. Road test with a manual record of acceptable braking characteristics

Where a brake test cannot be carried out, for whatever reason, the inspection record must be endorsed
with the reason why the test cannot be carried out. A brake test must be completed at the earliest
opportunity.

1.4 Minimum Performance Requirements

As part of the list of items to be inspected, several are subject to measurement in order to establish wear or
performance tolerances. Group Companies must ensure that wear limits or tolerances are set for these
items and that they are, at least, within the local legislative requirements, in all cases.

In order to demonstrate that a vehicle has undergone an appropriate safety inspection and that the
appropriate safety criteria have been met, the following items must be considered to be mandatory and
must be inspected and reported upon.

Wheel nut security
Tyre tread depths
Air system pressure (build up time)
Fuel Leaks (zero tolerance to leaking fuel)
Brake efficiency readings
Oil and fluid levels
Steering components
Emergency exits
Warning lights
Wheel chair lifts

Where there is any intervention on, or repairs to, a brake system or components are replaced, Group
Companies must ensure a secondary brake test is undertaken and record the results on the vehicle
inspection documentation. This is to ensure the vehicle has been fully tested and complies with required
minimum standards prior to being signed off and released for use.

It is also recommended that Group Companies include a process for quantification of those items which on
inspection, deem that a more detailed review must be undertaken before roadworthiness can be assured,
these will include, but may not be limited to:

Brake component wear (to include friction material e.g. pads and shoes)
Emissions
Oil leaks
Tyre pressures
Steering ball joint wear
