If you are 16 or older you can apply for a motorcycle endorsement. An unrestricted motorcycle endorsement allows you to ride any motorcycle. A restricted motorcycle endorsement only allows you to ride a 3-wheel motorcycle. For information see the Motorcycle & Moped Manual.
If you have a valid motorcycle-endorsed license from another state, the District of Columbia, a United States Territory or a Canadian Province, you can transfer that endorsement to your Oregon license without testing or training. Tell us that you want to keep your endorsement when you apply for your driver license. Make sure that the endorsement is on your license before you leave the office by looking for an M on the front of your license under Endorsements. If your license is issued without the endorsement, you must take any test or training required to add it later.
