I am 27 years old, from the state of Washington.

I have pretty severe driving phobia. I can be a passenger, but being behind the wheel causes me to have panic attacks which would be very dangerous.

However, I am able to drive a motorcycle. I am comfortable operating them and driving them in traffic.

Does anyone know if it is possible to get a motorcycle endorsement without the need of a driver's license? I do not think I will be able to pass a driving test in a car.

Any suggestions?
