If you have a dot physical card can you drive a vehicle with air brakes?
Your medical card has to do with your medical condition and has nothing to do with air brakes. Air brakes is an endorsement on your license. To qualify for driving a vehicle with air brakes, you must first complete a written test on air brakes and when you pass that test, your license can receive the air brakes endorsement. There are also endorsements for HazMat, combination vehicles, motorcycles, school buses, etc.. But regarding your medical card, it has its own expiration date separate from your license and its duration depends on your prior medical condition. If you have perhaps Diabetes you may be required to see a doctor every month to keep your license. High bloodpressure, or sleep apnea also affect your medical card. If you are healthy you may need to renew it once in three years depending on the state in which you live.
