- When a driver is stopped over for by a police officer on the suspicion of drunk driving, the law enforcement officer is expected to ask him/her to pass one or more field sobriety tests, in order to check whether a driver is under the influence of alcohol by evaluating the examination of mental and physical activities.
According to the National Highway Traffic Safety Administration (NHTSA), there are three tests which have been examined and labeled Standardized Field Sobriety Tests. These include the Walk and Turn, One Leg Stand and Horizontal Gaze Nystagmus.
1. Walk and Turn
The driver will be asked by the law enforcement officer to walk in a straight line, heel to toe, and then turn and walk the other way. This test is used to evaluate a driver’s balance and power to abide by directions.
