Yes. One of the most frequent causes of drunk driving arrests is being pulled over for something as trivial and an vehicle equipment violation. Some commonly cited equipment violations frequently used to justify a stop and subsequent DUI investigation include: defective headlight, taillight, brake light, absence of license plate, etc.
To prevent a possible DUI investigation, do your best to make sure your vehicle is free from easily apparent equipment violations. Do not make the mistake of exposing yourself to a DUI stop and arrest for an easily correctable equipment violation. A stop based solely on a vehicle code equipment violation is lawful and constitutional. Such a stop can lead to a DUI arrest and driver’s license suspension.
