5 Ways Police Can Detect Drunk Drivers

5 Ways Police Can Detect Drunk Drivers

Based on thorough study and interviews of law enforcement authorities making tens of thousands of DUI and/or DWI arrests, the National Highway Traffic Safety Administration (NHTSA) compiled a list of visual cues to help the police detect drivers under the influence of alcohol or drugs on the road. Police officers understand that motorists who show these signs are likely to be drunk driving.

The following are the five common signs that indicate intoxicated driving, according to law enforcement:

  • The driver has trouble staying within a driving lane – Impaired drivers often have a difficult time maintaining proper and steady lane position, as well as driving between lanes. Common examples include swerving, weaving across multiple lanes, straddling the center line or roadside, or making an extremely wide turn.
  • The driver experiences speed and braking issues – From sudden acceleration or braking to trouble maintaining the proper speed, intoxicated drivers have problems judging speed and distance while on the road. Common braking issues which indicate drunk driving include stopping at an odd angle, stopping way before or beyond an intersection, or making short and jerky stops. Common speeding issues include driving at more or fewer than 10 mph over the posted speed limit, driving at different levels of speed, and sudden acceleration without any valid reason.
  • The driver has awareness and vigilance issues – Another common indicator of drunk driving is when a motorist fails to notice road conditions, such as traffic signals and the movement of traffic. Common examples of vigilance problems include going against the traffic signal, slowly responding to traffic signals, driving the wrong way, failing to use headlights when driving in the dark, and using the wrong turn signal when changing lanes or making turns.
  • The driver has judgment difficulties – Every driver must always remain alert while on the road. However, drunk drivers typically take more risks compared to sober motorists. Common judgment problems include making erratic and unsafe lane changes, tailgating, making illegal turns, and driving in the wrong lane.
  • The driver has visual signs of intoxication after traffic stop – When a police officer stops a vehicle on reasonable suspicion of drunk driving, common signs of driver intoxication include the smell of alcohol, red eyes, slurred speech, delayed responses to questions, and poor motor skills and reflexes.
