What should you do to prevent a vehicle fire?
- Never start a vehicle with a fuel leak.
- Maintain proper tire pressures.
- Make sure your vehicle's brakes are fully released while your vehicle is moving.
- Do all of the above. ✓
Answer: D. Do all of the above.
Do all of the above: never start a vehicle with a fuel leak, maintain proper tire pressures, and make sure the brakes are fully released while the vehicle is moving.
Why this is the answer
The handbook lists all three as fire-prevention measures. It says never start a vehicle that has a fuel leak; soft tires build heat and can cause a fire, so check tire pressure often; and dragging brakes create heat that can ignite grease in the hubs, so all brakes must be fully released while moving. Since each listed action is supported by the handbook, doing all of them is the answer.
Why the other answers are wrong
- A. Never start a vehicle with a fuel leak. — This is a real fire-prevention step, but by itself it does not cover the tire-pressure and brake-release measures the handbook also requires.
- B. Maintain proper tire pressures. — Checking tire pressure is a real fire-prevention step, but by itself it does not cover the fuel-leak and brake-release measures the handbook also requires.
- C. Make sure your vehicle's brakes are fully released while your vehicle is moving. — Releasing the brakes fully is a real fire-prevention step, but by itself it does not cover the fuel-leak and tire-pressure measures the handbook also requires.
Remember it
Fire prevention check: fuel leak, no start; soft tires, heat; dragging brakes, heat.
