Every applicant takes general knowledge. Air brakes is for vehicles with air brakes, and combination vehicles is for Class A. Each is a separate test, passed at 80%.

How the tests are scored

You need at least 80% on each test. Below 80% on air brakes puts an air brake restriction on your license, and below 80% on combination vehicles means no Class A. This practice test shows the share you got right in each area, which is where to start.
