Oklahoma driving lesson · Keeping Your License Valid
Restriction and endorsement codes
A 4-minute lesson from the Oklahoma course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Restrictions and endorsements are meant to improve your safety, not interfere with your driving. An endorsement shows you're qualified for a certain type of vehicle, such as a motorcycle or a truck carrying hazardous materials. A restriction is a condition that affects your safety as a driver.
Know the rule
Restrictions are listed as a code on your license and explained on the back of the license.
Under 16: no more than 300cc, ride only 4:30 a.m.-9:00 p.m., no passenger; under 150cc also max 35 mph and no posted-minimum-speed highways. Lifted at 16.
Instruction from a parent, legal guardian or anyone 21+ with a valid Oklahoma license with a motorcycle endorsement, who has visual contact with the operator.
When a restriction is no longer needed (such as a learner or physical restriction) or is in error, contact a driver license examiner at a Service Oklahoma location.
To add an endorsement, you must see a driver license examiner and pass the required tests. Other endorsements and restrictions apply to commercial licenses.
You're 17 with a "T" restriction and your shift ends at 11 p.m. You may drive yourself home because the trip is work-related. Driving to a friend's house at 11 p.m. would need a licensed driver at least 21 with you.
