In most states, driving without insurance is an offense that comes with hefty consequences. Aside from New Hampshire and Virginia, all states require some form of auto insurance to legally drive and/or register your vehicle.
And if you get caught driving without car insurance, the penalties can be severe. Besides having your license and registration suspended, you may be required to carry SR-22 or FR-44 insurance, which refers to certificates of financial responsibility required to be filed by high-risk drivers and which can increase your auto insurance rates.
