What safety equipment is required in a commercial vehicle?

The correct choice highlights essential safety equipment required in a commercial vehicle, which is vital for ensuring the safety of the driver, passengers, and other road users.

A fire extinguisher is crucial as it allows for immediate response to small fires, potentially preventing them from escalating into more serious incidents. Warning triangles serve as visual alerts to other drivers if the vehicle is stopped on the road, helping to prevent accidents by increasing visibility during breakdowns or emergencies. Additionally, a first aid kit is necessary for addressing any injuries that may occur, whether in minor accidents or during any other situation where immediate medical assistance is required.

The other options, while they contain some useful items, do not encapsulate the core requirements as effectively. Traffic cones can be useful in certain circumstances, but they are not universally required for all commercial vehicles. A toolbox and extra tires, while they could be beneficial for maintenance or fixing issues on the road, are not strictly mandated safety equipment. Flashlights and safety goggles, although helpful for specific situations, do not form a standard requirement list for commercial vehicles.

Thus, the chosen answer encompasses the most critical tools for effective safety management on the road.
