Ala. Code § 45-49-101.05

The owner of a vehicle that has been issued a notice of violation shall be responsible for payment of the civil fine unless the owner successfully transfers responsibility, there is an adjudication that no violation occurred, or there is an otherwise lawful determination that no civil penalty shall be imposed. All owners of a vehicle who are mailed or receive a notice of violation shall be jointly and severally liable for payment of the civil fine. The county or municipality may collect the civil fine in the same manner as any other debt owed to Mobile County or municipality located in Mobile County.
