What type of brakes must trucks transporting metal coils have?

Trucks transporting metal coils are required to have air brakes or an equivalent braking system primarily due to the significant weight and potential hazards associated with the load. Air brakes are particularly effective for larger vehicles like trucks, providing reliable stopping power and better control when handling heavy and potentially shifting loads such as metal coils.

Unlike some other braking systems, air brakes offer superior performance for heavy-duty applications, ensuring that the vehicle can decelerate safely and with proper responsiveness. This is crucial in preventing accidents, especially when traveling on highways or navigating urban environments.

While other types of brakes, such as disc, hydraulic, or drum brakes, can be effective for various vehicle types and loads, they may not provide the same level of control and safety required for the specific challenges posed by transporting heavy metal coils. The need for an air brake system or equivalent ensures compliance with safety regulations and helps protect both the driver and surrounding road users.
