The fine for driving without Auto Insurance will depend on the state you live in and get caught driving without auto insurance in.
Expect to get your vehicle towed away as well if the cop has an attitude.
You can have your license suspended for 45 days and the fine could cost upwards of $500.00 or more.
It's a very bad idea to drive without auto insurance because the fines and court costs as well as towing and impound fees could cost more than the insurance would cost.
