The vehicle has everything needed for FMVSS-108, but the State Police gave me a ticket anyway. What’s the deal?

States can regulate anything not covered by FMVSS-108, such as any accessory lamps or lamps that are not mandated by FMVSS-108. Generally, the problem is in these areas; sometimes, however, it can simply be a mistake. In that case, Truck-Lite can often write a letter to clarify the issue.
