This comprehensive guide breaks down what you can and cannot do when modifying your vehicle in West Virginia.

Status: Conditional | Underglow in West Virginia
West Virginia allows underglow lighting systems, but with important restrictions on color and visibility while driving.

West Virginia requires no cover; the limit is four auxiliary, spot, or front lamps over 300 candlepower lit at one time on a highway. See Light Bars & LED Lighting in West Virginia for the full breakdown. Get the exact limits, statute citations, and a printable PDF in your compliance report.
Headlight & Taillight Tint
Status: Illegal
Smoked or tinted film on headlights and taillights is illegal in West Virginia. Headlights must emit white light and taillights must show red at the required visibility distance, and tint that dims or discolors them violates those requirements. See Headlight & Taillight Tint in West Virginia for the full breakdown. Get the exact limits, statute citations, and a printable PDF in your compliance report.
Exhaust Modifications
Status: Conditional | Aftermarket Exhaust in West Virginia
West Virginia requires vehicles to have functional mufflers and prohibits excessively loud exhaust systems. Aftermarket exhaust components are allowed as long as they meet noise requirements and maintain required emissions equipment. Get the exact limits, statute citations, and a printable PDF in your compliance report.
Window Banners
Status: Conditional
A sun-screening device may be used only along the top of the windshield and may not extend below the AS-1 line or more than 5 inches from the top, whichever is closer to the top; it must be non-reflective and not red, yellow, or amber. Because the material must be transparent, a printed or opaque banner is not legal in West Virginia — only a clear tint band. See Window Banners in West Virginia for the full breakdown. Get the exact limits, statute citations, and a printable PDF in your compliance report.
License Plate Frames
Status: Conditional
Frames are legal if nothing is obscured; the plate must be clearly visible and maintained free from foreign materials in a condition to be clearly legible. See License Plate Frames in West Virginia for the full breakdown. Get the exact limits, statute citations, and a printable PDF in your compliance report.
Staying Compliant
West Virginia generally provides vehicle enthusiasts with substantial freedom for modifications, focusing primarily on safety-related requirements rather than restricting modifications themselves. The key to staying legal is maintaining your vehicle's essential functions while enjoying the creative freedom the state's permissive laws provide.
