Question

Which of the following causes vehicle fires?

1. Short circuits and loose connections
2. Flammable cargo with proper ventilation
3. Spilled fuel cleaned up quickly and properly
4. Driver smoking in a rest area

Answer 1

Short circuits and loose connections are common causes of vehicle fires, while proper handling of flammable cargo and quick cleanup of spilled fuel reduce fire risks. Smoking in a rest area is less likely to cause vehicle fires if done responsibly.

Step-by-step explanation:

The causes of vehicle fires can include various factors associated with combustion and flammable materials. The options provided point to potential causes, with short circuits and loose connections being a common reason for vehicle fires.

These electrical issues can lead to sparks and overheating, which may ignite flammable materials, like oil or gas, within the vehicle.

However, flammable cargo with proper ventilation, while a risk, is less likely to cause a fire if managed correctly. Spilled fuel that is cleaned up quickly and properly also reduces the risk of a fire.

Lastly, while smoking has the potential to ignite fumes or materials, a driver smoking in a rest area is not generally considered a direct cause of vehicle fires, assuming they follow safety protocols and dispose of cigarettes properly.
