Different commercial driving roles require different sets of license endorsements, as each qualification relates to a vehicle feature or cargo. Some professions demand a single endorsement while others may warrant three or four! The most common among all those on offer is the Air Brakes endorsement, as this feature applies to a greater variety of vehicles than any other addressed with a CDL endorsement exam. The chances are that if you require any endorsements at all, Air Brakes will be one of them! Every Class B and Class A vehicle built in the past few decades is required by law to use an air braking system, which is why so many drivers need the associated qualification. You will at some point need this WA CDL air brakes practice test to help you study for an Air Brakes qualification if you eventually intend to drive a flat-bed, any type of combination truck-trailer, tanker vehicle, box-truck, school bus, city bus or multiple-trailer vehicle. As the qualification is compulsory, it makes sense to apply for it immediately following your pass on the CDL general knowledge Washington state permit test.

Drivers of the largest Class A commercial vehicles have a second compulsory qualification in the form of the Combination Vehicles endorsement, which should be applied for - where applicable - when you have successfully completed the CDL air brake test for WA state learners.
