Being pulled over by a police officer can be a stressful and intimidating experience, especially if the officer may have reason to believe that a person was driving while under the influence of alcohol or drugs. An officer will look at a number of factors when determining whether a person may be intoxicated, and in some cases, a driver may be asked to take field sobriety tests. These tests involve multiple physical or verbal activities that allow an officer to gauge a person’s level of intoxication, and the results of these tests may provide probable cause to make an arrest. Drivers can be sure they are addressing these situations properly by understanding the types of tests they may be asked to perform and how these tests may indicate intoxication.
Standardized Field Sobriety Tests
People may be familiar with tests that may be used by a police officer to determine whether a driver is intoxicated, if only because they have seen them performed on TV shows. Some of these depictions may involve a person being asked to recite the alphabet backwards or touch their fingertips to their nose. However, there are only three Standardized Field Sobriety Tests (SFSTs) that are approved by the National Highway Traffic Safety Administration (NHTSA):
Walk and turn - In this test, an officer will ask a person to stand with the heel of their right foot touching the toe of their left foot. They will then be asked to take nine heel-to-toe steps in a straight line with their arms at their sides, turn around, and take nine steps to return to their original position. If a person loses their balance, steps off the line, stops walking to steady themselves, raises their arms to maintain balance, does not turn correctly, or otherwise fails to follow the officer’s instructions, this may be seen as an indication that they are intoxicated....
