Vehicle
Structure
Figures 1 to 4 in Appendix C show various typical vehicle structures where the
shaded portions indicate the important load-bearing parts. Note: The prescribed
areas are those specifically detailed in Sections 2, 3 and 5 of the Manual.
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.
Body Condition
This part of the examination applies to all vehicles

Vehicle
Structure
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.
Body Security
2. Examine the following items for presence, security, fracture, distortion, excessive
wear or damage
a. all fixings (e.g. brackets) securing the body and its supporting members to
the chassis
b. all fixings (e.g. 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
4. Examine the body work for excessive corrosion or damage resulting in sharp
edges which are likely to cause injury.

Vehicle
Structure
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
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 30cm of the body mountings
Body Condition
4. A sharp edge or projection, caused by corrosion or damage, which renders the
vehicle dangerous to other road users, including pedestrians.
