{"id":569,"count":50,"description":"If you plan on driving any CMV equipped with air brakes, you must take and pass the air brakes test to remove the air brakes restriction from your CDL.  The air brakes test is different than the endorsement tests because the air brakes test works as a restriction instead of an endorsement.  If you do not pass the air brakes test, your CDL will bear a mark of restriction which means that you are not authorized to drive a CMV with air brakes.","link":"https:\/\/mcqacademy.com\/en\/topic\/air-brakes-test\/","name":"Air Brakes Test","slug":"air-brakes-test","taxonomy":"topic","meta":[],"_links":{"self":[{"href":"https:\/\/mcqacademy.com\/en\/wp-json\/wp\/v2\/topic\/569","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mcqacademy.com\/en\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/mcqacademy.com\/en\/wp-json\/wp\/v2\/taxonomies\/topic"}],"wp:post_type":[{"href":"https:\/\/mcqacademy.com\/en\/wp-json\/wp\/v2\/mcq?topic=569"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
