What is the purpose of a "fire extinguisher" in a commercial vehicle?

Answer: B — To extinguish fires and prevent accidents

The primary purpose of a fire extinguisher in a commercial vehicle is to extinguish fires and prevent accidents. In the event of a fire, whether due to mechanical failure, an accident, or a load failure, having a fire extinguisher on board allows the driver to quickly address small fires before they escalate into more significant hazards. This ability can protect both the vehicle and its occupants, as well as other road users. In commercial settings especially, where vehicles often carry flammable materials or goods, the presence of a fire extinguisher is not only a safety measure but may also be a regulatory requirement. Proper training on the use of fire extinguishers and understanding their locations in the vehicle are crucial parts of ensuring safety on the road.
