The short answer is yes. While your vehicle may be modified in an entirely safe and responsible manner, the police have the right to complete safety inspections on a vehicle. If the officer looks at your vehicle, and has reason to believe that your car may violate a state law concerning equipment or safety – such as headlights, taillights, noise or ‘general safety’, they may pull you over and inspect your vehicle. If, while they have you pulled over, they notice something out of place – such as the odor of marijuana, evasive attitude or signs of intoxication – they may begin to investigate those items of interest. Thus, if it’s modified, be careful.
