According to the NHTSA, about 29 people die each day in the United States in alcohol-impaired vehicle crashes – that’s one person every 50 minutes. Drunk driving is a serious issue, and it’s important to know the signs of an impaired person on the road.

Look for these signs to tell if a driver is under the influence:
Speed and braking
Impaired drivers normally have a hard time judging speed and distance. Watch out for:
- Sudden acceleration or deceleration for no reason
- Jerky stops or stopping too short
- Not stopping soon enough or stopping to quickly
Problems staying within their lane
Intoxicated drivers have difficulty maintaining a steady position. Look for:
- Weaving through traffic and across lanes
- Swerving back and forth
- Drifting towards one side of the road
Awareness
Impaired drivers often fail to notice traffic conditions, signs, stop lights or other vehicles on the road. Watch for:
- Slow or late responses to traffic signals
- Driving the wrong way or in the wrong direction
- Driving in the dark without headlights
- Using the wrong turn signal when making turns
- Almost striking objects or other vehicles
Difficulties with judgement
Impaired drivers are more likely to engage in riskier driving behaviors.
- Tailgating other vehicles
- Making illegal turns
- Erratic lane changes
- Driving off of the road
Stay aware of possible drunk drivers using these signs. If you see a driver that may be impaired, call 9-1-1 to report the vehicle and keep your distance – for your own safety and the safety of everyone else on the road.
