An obsolete system of registering interstate motor carriers to verify that they
have the proper operating authority and auto liability insurance in place to
operate in interstate commerce. The identification stamps (known as bingo
stamps) of all the states in which the motor carrier operated and fulfilled its
requirements were affixed to a cab card that was carried in the motor vehicle
at all times. The bingo card program was replaced by the single state
registration system (SSRS), which was subsequently replaced by the Unified
Carrier Registration Agreement (UCRA) plan.
