Reason for rejection
Vehicle Structure
Appendix C figures A to D show typical different vehicle structures where the shaded portions indicate the important load-bearing parts.
1. With the vehicle over a pit or on a raised hoist, check the vehicle structure for any fracture, damage or corrosion, not within the prescribed areas, which is likely to affect prejudicially the correct functioning of the braking system or the steering gear,
Note: The prescribed areas are those specifically detailed in Sections 2, 3 and 5 of the manual.
1. Any deliberate modification, excessive corrosion, damage, fracture or inadequate repair not within a prescribed area which adversely affects braking or steering by severely reducing the strength or continuity of a main load bearing structural member.
Body Security
This part of the examination applies to vehicles with separate bodies.

Individual defects
Individual defects are not subject to Reason for Rejection 2 or 3 unless their cumulative effect is likely to reduce significantly the overall body security.
2. Examine the following items for presence, security, fracture, distortion,
excessive wear or damage
a. all fixings (eg brackets) securing the body and its supporting members to the chassis
b. all fixings (eg brackets) securing the body to a sub-frame or supporting members, and all securing bolts, rivets or welds for all the above
fixings.
3. Check the condition of the body and chassis in the vicinity of the mounting points-Body condition

2.
a. Excessive displacement of the body relative to the chassis which might lead to loss of control of the vehicle when driven
b. insecurity of the body or its
supporting members to the chassis so that it is clear that there would be a danger to other road users.
3. Any deliberate modification, excessive corrosion, damage, cracks or inadequate repair of a load bearing body or chassis member which seriously affects its strength within 30 cm of the body mountings.
Body Condition

Body Condition
Body condition
This part of the examination applies to all vehicles.

4. Examine the body work for excessive corrosion or damage resulting in sharp edges which are likely to cause injury,
4. A sharp edge or projection, caused by corrosion or damage, which renders the vehicle dangerous to other road users, including pedestrians
