You're on your way home from a night out, and suddenly, you see flashing blue lights behind. A suspected drunk driving traffic stop can lead to an arrest, and next thing you know, you may be facing criminal charges and other penalties. The implications of a DUI traffic stop are significant.
Pennsylvania law enforcement cannot pull you over simply because they want to. There must be a valid reason to stop a driver. There are laws that prohibit unreasonable stops and the harassment of citizens who are not breaking the law. If police notice a driver exhibiting behaviors that could potentially indicate drunk driving, this is reasonable suspicion. Without reasonable suspicion, however, a DUI traffic stop is invalid.
