If you plan to register your motorcycle on base, you may wish to request an MSF Card. This may save time and aggravation when you move to another state. If the local program does not issue MSF cards, contact the Safety Center. In courses conducted by the state, motorcycles are provided. Often riders prefer to take the state-sponsored course if they do not wish to use their personal motorcycle in the course.
Costs are quite reasonable.
RSS meets the Navy requirement. This is a common situation with people who learn to ride overseas. You should check with your state when you return. Most state regulations exempt military fire fighters from commercial driver license requirements. However, civilians may be required to obtain a special non-commercial driver license with a special endorsement for the weight and class of vehicle to be driven whether it is on or off base.
