Which of the following is true regarding the use of air brakes?

The statement regarding the requirement for proper training and understanding when using air brakes is accurate because air brakes operate differently from hydraulic brakes and have unique characteristics that drivers must be familiar with. Air brakes rely on compressed air to function, which means that their components, such as the air compressor, lines, and chambers, require specific knowledge for safe and effective operation. Understanding the air system, including the potential for air pressure loss and the implications for braking performance, is essential to prevent accidents. Proper training ensures that drivers know how to manage these systems, conduct pre-trip inspections, and respond appropriately in various driving conditions.

In contrast, while air brakes are widely used in larger vehicles like trucks and buses, they are not typically found in smaller passenger vehicles. Additionally, air brakes can be effective even in winter conditions with proper maintenance and understanding. They do provide substantial stopping power, often making them more effective than hydraulic brakes in heavy-duty applications.
