DL-123 insurance forms are unique to North Carolina, but other states have similar forms that are issued for drivers requiring them. The most common of these is the SR-22, which is required in many states for drivers who have had their license suspended. Generally, these forms are submitted to the state's DMV to prove that the individual named does have the required minimum amount of auto insurance to be on the road legally. Although SR-22s are the most common type, Virginia and Florida issue a similar form called the FR-44, while Maryland's version is called the FR-19 and Indiana has the SR-50. Each state's certificate has rules and restrictions that are unique to that location.
