Any vehicle that has an air brake system must have attached to their license a Z endorsement. After testing fees have been completed, we can walk you through a step by step of the practical portion and terminology to better prepare you for your test. If you own a recreational vehicle that has air brakes, this would be beneficial for you! A lot has changed from a standard wedge s-cam brake drum to a sophisticated disc brake system to which most systems now operate. You must provide the vehicle in which you are being tested on or operating and we will do the rest! We do have an up to date driver’s handbook to loan. A small retainer is required. Call or email us through our contacts page.
