An Air Brake Endorsement is a special qualification that allows drivers to operate vehicles with air brake systems, which are commonly found on buses and large commercial vehicles. It's like an extra certification on top of a regular driver's license that proves a driver knows how to safely operate these more complex braking systems. This endorsement is required by law for anyone driving buses or similar large vehicles that use air brakes. Think of it as a "seal of approval" that shows employers their potential driver understands how to properly use and check these important safety systems.
