Complete Guide to Vehicle Modification Laws in Alabama
Alabama offers vehicle enthusiasts considerable freedom to modify their rides, with most modifications falling under conditional approval rather than outright bans. Understanding the specific requirements for each type of modification will help you stay legal while expressing your automotive creativity. This comprehensive guide breaks down the key rules for popular vehicle modifications in the Heart of Dixie.
Window Tint
Status: Conditional

Alabama allows auxiliary lamps on the road — no cover is required and they need not be switched off — but only one auxiliary driving lamp (mounted 16 to 42 inches), two fog lamps, and one spot lamp are permitted, and anything over 300 candlepower must be aimed so no part of the beam strikes the road beyond 75 feet.

Headlight & Taillight Tint
