Drunk Driving

Driving Evidence

The National Highway Traffic Safety Administration (part of the Department of Transportation) has produced a guide for detecting drunk drivers at night. These are the 20 signs that officers look for when determining whether to investigate for D.U.I.

• Turning with wide radius
• Straddling center of lane marker
• Appearing to be drunk (based upon posture, gestures, etc.)
• Almost striking object or vehicle
• Weaving
• Driving on other than designated roadway
• Swerving
• Speed * (more than 10 miles below legal limit)
• Stopping without cause in traffic lane
• Following too closely
• Drifting
• Tires on center or lane marker
• Braking erratically
• Driving into opposing or crossing traffic
• Signaling inconsistent with driving actions
• Slow response to traffic signals
• Stopping inappropriately (other than in a lane)
• Turning abruptly or illegally
• Accelerating or decelerating rapidly
• Headlights off

* NOTICE - SPEEDING IS NOT ONE OF THE TOP 20 CLUES OF D.U.I. This is powerful in the hands of a competent defense attorney if your D.U.I. came from a traffic stop for speeding only!
