Single State Registration System
Also known as: SSRS

Definition
The Single State Registration System (SSRS) is the pre-2007 program UCR replaced. Under SSRS, carriers filed proof of insurance and paid fees state-by-state for each state they operated in. UCR consolidated that into one annual fee paid to a single base state, scaled by fleet size instead of by state count. SSRS is obsolete, but the term still appears when explaining why UCR exists. The replacement was created by 49 USC §14504a in 2005, and UCR fees are shared among the participating states to fund motor-carrier safety programs.
