Do you need to establish:
- How has the damage to a crucial vehicle component occurred?
- Did the damage occur during the accident, or at some earlier stage?
- Is the damage likely to have caused inability to control the vehicle?
- Should the driver or operator have been aware of the damage?
- Has there been malicious damage to the component?
Failure types that can arise:
- Metals (impact failures, fatigue cracking, corrosion, wear, casting defects, welding defects, not-to-specification metal)
- Tyres (delamination and tread detachment, kerb crush-damage, puncture and repair issues, tread recutting, x-ray examination of damage)
- Wheels (impact damage, detachment, cracking)
- Vehicle light bulbs (state of illumination at impact, pre-accident failures, manufacturing defects)
- Brakes (accident damage, pre-accident defects, heat damage)
- Towing connections (trailer detachment, pre-accident damage)
- Seat belts (evidence of use, retractor defects, buckle locking mechanism failure, attachment failures)
Most of these fall into the following 3 groups:
1. Primary Safety (i.e. items that affect control of the vehicle)
- Tyres & Wheels
- Trailer couplings
2. Secondary Safety (i.e. items that protect the vehicle occupants)
- Seat belts
3. Other (i.e. items that provide conspicuity or information for the driver)
- Light bulbs
- Speedometers and other instruments
