Police officers are trained on what to look for when deciding whether to pull you over for suspected drunk driving, and understanding why the officer stopped you can help you be better prepared to make decisions about your defense strategy. Officers usually suspect a driver of operating under the influence based on observations while the vehicle is moving.
Reckless driving is one indicator of an impaired driver, as alcohol and other substances can alter your ability to make good decisions while driving. Drivers may speed up or slow down quickly or without apparent reason, drive to close to the car in front of them or turn without signaling or slowing down. In extreme cases, the driver may even be driving on the wrong side of the road.
