What basic maintenance should be performed on a vehicle before transporting metal coils?

Before transporting metal coils, it is essential to ensure that the vehicle is in good working condition and safe to operate. Inspecting brakes, tires, lights, and securement devices is crucial because each of these components plays a significant role in both the vehicle's operational safety and the secure transport of heavy loads like metal coils.

Brakes must function properly to allow for safe stopping, especially when dealing with the added weight and potential shifting of cargo. Tires must be adequately inflated and in good condition to maintain traction and stability while driving. Lights are necessary for visibility and communication with other drivers on the road. Finally, securement devices are vital for ensuring that the metal coils remain safely fastened and do not shift during transport, which could lead to accidents or cargo loss.

While changing the engine oil, washing the exterior, and testing radio equipment might be part of vehicle maintenance, they do not directly pertain to the immediate safety and readiness for transporting metal coils. Hence, the most critical maintenance step before transport focuses on the vehicle's operational elements and securement capabilities.
