Which three types of emergency equipment must you carry in your vehicle?

Carrying a spare electrical fuse, a fire extinguisher, and warning devices for parked vehicles is essential for any commercial driver as these items provide critical support in emergencies.

The spare electrical fuses enable quick repairs to minor electrical issues that could leave a vehicle inoperative. A fire extinguisher is crucial for extinguishing small fires before they become uncontrollable, especially in cases of vehicle malfunction or accidents. Warning devices, such as cones or triangles, are essential for ensuring the safety of the vehicle operator and other road users by making other drivers aware of a potential hazard on the road. This preventive measure significantly reduces the risk of further incidents.

Other options suggest useful items but do not encompass the specific requirements mandated for commercial drivers in Kentucky, which emphasize safety and the ability to handle emergencies effectively.
