Transport vehicles such as train, trucks, buses are used every day to transport both goods and people. An important safety feature on these vehicles, the air brake system, is used to control speed. The US Department of Transportation Federal Motor Carrier Safety Administration (FMCSA) regulates the use of air brakes and sets standards for maintaining and operating these systems. Drivers of vehicles equipped with air brakes need to know the components of the systems, how they work, and how to use them, and make sure they're operating safely. This course introduces the components that work together to create an air brake system, guidelines on operating a vehicle equipped with air brakes, and checklists for inspecting air brake systems and the air brakes on both single and combination units. DOT: Air Brakes was developed with subject matter support provided by EnSafe Inc., a global professional services company focusing on engineering, environment, health and safety, and information technology. Please note, the course materials and content were current with the laws and regulations at the time of the last expert review, however, they may not reflect the most current legal developments. Nothing herein, or in the course materials, shall be construed as professional advice as to any particular situation with respect to compliance with legal statutes or requirements.
