Amateur Radio

These plates are issued to amateur (ham) radio operators.

This type reportedly was first available on March 1, 1956. These plates were black on reflective white scotchlite.

The operator’s callsign is the registration number, with the neat lightning bolt separator. The lightning bolt seems to get smaller and smaller with every iteration.


Around 1981, these plates were also made available for use on Combination registrations. Commercial and Camper are available today as well.
