This ordinance ends the practice of impoundment for many non-driving and non-public safety related offenses including possession of fireworks, possessing spray paint, or loud music. When impoundment is a sanction, the ordinance reduces administrative fines and caps the amount of storage fees regardless of the size of the vehicle or the duration of the storage.
The ordinance also reduces the amount of the administrative penalty for driving with a suspended or revoked license and specifies that the impoundment and the administrative fine do not apply when a license is suspended for nonpayment of parking, standing, compliance, automated speed enforcement system, or automated traffic law enforcement system violations or for the failure to comply with emission testing.
