The State of Alabama has a minimum requirement of liability auto insurance coverage that needs to be met in order to drive legally on public access roads. If a driver is involved in an auto accident or is pulled over and does not have minimum auto insurance liability coverage that driver will receive a ticket for not following the state law. If you have extra cash laying around, another option that you can use to substitute for Alabama auto insurance is a cash deposit or liability bond of at least $50,000. But under the Alabama state law, in order to operate a vehicle in Alabama on public access roads you must have any of the three :

Alabama Liability Auto Insurance Coverage of 25K/50K/25K

or

An Alabama Liability Bond or Cash Deposit of at least $50,000

The state of Alabama requires a minimum of requirement of :

$25,000 for personal injury liability

$50,000 for all injuries in one accident 

$25,000 for property damage, also per accident.

When driving on public streets in Alabama, the driver must carry proof of insurance - liability auto insurance or the alternative bond or proof of cash deposit. If a driver is caught without proof of insurance, the vehicle tag registration may be suspended by the Alabama Department of Revenue. The suspension shall last until the driver presents proof of insurance. Upon presenting valid proof of Alabama auto insurance, a reinstatement fee of $100 is needed to get back on the road. If a driver is caught a second time, their Alabama drivers license will be suspended for four months. After four months, they will then have to pay a $200 reinstatement fee and still must present some sort of proof of financial responsibility.
