A driver or motorist is usually stopped by a law enforcement officer for a minor traffic infraction. These traffic infractions can vary from weaving, speeding, failure to use a turn signal, running a red light, expired license plates. There can also be vehicle safety issues that are the basis for pulling the driver over. These can range from a cracked windshield; lights not working on the headlights, taillights, and license plates. As most DUI attorneys and DUI lawyers will agree, the purpose for stopping the car is actually the start of a DUI investigation. If the basis of the stop is based on a violation of the driver, this is considered the initial indicator that the driver might be DUI, DWAI, driving drunk, all by alcohol or drugs or both alcohol and drugs. If the driver requests an attorney or lawyer during the stop, the cop will inform the driver that they do not call attorneys or lawyers to the location where the driver was pulled over.
