Air brakes are a type of brake system that uses compressed air to actuate the brake shoes or pads. Air brakes are typically used on heavy vehicles, such as trucks and buses, because they are more powerful and reliable than hydraulic brakes.
If you drive a truck with air brakes for company, you will need a CDL if the GVWR of the truck is 26,001 or more pounds. If the GVWR of the truck is less than 26,001 pounds, you may not need a CDL, but you may still need a special license or permit depending on the state in which you live.
It is important to note that the CDL requirements may vary from state to state. Therefore, it is always best to check with the licensing authorities in your state to determine the specific requirements for operating a truck with air brakes.
