What are three essential pieces of emergency equipment a vehicle should have?

The three essential pieces of emergency equipment a vehicle should have include a fire extinguisher, three reflective triangles, and spare fuses.

A fire extinguisher is crucial because it can help prevent a small fire from becoming a disaster, especially in a commercial vehicle where flammable materials or fuel might be present. The importance of having three reflective triangles cannot be overstated, as they provide a way to alert oncoming traffic in case of a breakdown or accident, significantly improving safety. Spare fuses are also important to have on hand, as they can be used to replace any blown fuses, ensuring essential electrical components in the vehicle remain operational.

While the other options include useful items, they either lack certain critical safety items or do not align with the standard requirements for emergency preparedness in a commercial vehicle. For example, while road flares and a flashlight are helpful tools, they do not necessarily cover the essential equipment outlined in option B. Having the right combination of items is vital to ensure both vehicle operation and safety during emergencies.
