Which three emergency items must be present and secured in the vehicle?

The correct answer includes essential emergency items that are critical for ensuring safety and compliance during transit operations. A fire extinguisher is crucial for addressing any small fires that may arise during a trip, especially in a vehicle that can be exposed to various heat sources. Fuses are necessary for electrical repairs and maintaining the functionality of essential systems in the event of a failure, thereby enhancing safety on the road. Reflective triangles serve as warning signals to alert other drivers of a potential hazard, such as a breakdown, which helps to prevent accidents and injuries.

While the other options include some valuable items, they do not encompass the full range of necessary emergency equipment in the same way. Always having these three items—fire extinguisher, fuses, and reflective triangles—ensures that your vehicle is well-prepared for emergencies, thus complying with safety regulations and contributing to a safer environment for everyone on the road.
