In the meantime, read to learn three common field sobriety tests in Wyoming:

1. HGN Testing

The Horizontal Gaze Nystagmus Test is one of three standardized field sobriety tests, according to the National Highway Traffic Safety Administration. This test evaluates if the eyes jerk at high peripheral angles.

If someone is under the influence of alcohol, then it is likely that nystagmus is exaggerated. According to the NHTSA, it may also occur at lesser angles.

During the test, the officer will look for three indicators of impairment:

  • If the eye is not able to follow a moving object;
  • If there is distinct jerking;
  • And if the angle of the jerking is within 45 degrees.

2. One Leg Stand Test

The one leg stand test is a common field sobriety evaluation. The officer will ask you to stand on one leg with the other foot approximately 6 inches off the ground. You must then count aloud until the officer instructs you to lower your leg.

The officer will be looking for signs of imbalance, hopping, swaying, using arms to maintain balance and putting the foot down. Research indicates that this test is 83 percent accurate in determining if someone has a BAC level of 0.08 or greater.

3. Walk and Turn Test

During the walk and turn test, the officer will instruct you to walk nine steps heel-to-toe in a straight line. Once you have taken all of the steps, you must turn around on one foot and return to your starting position in the same manner.

According to AAA, the officer will be looking for eight factors, including imbalance, ability to listen to instructions, if you begin before the officer finishes giving instructions, if you stop walking mid-way through the test, if your heal does not touch your toe, if you step off the line or if you make the turn at the wrong moment.

Not all field sobriety tests are accurate ways to determine your alcohol levels, and you may be able to challenge their results. As such, it is important to contact a DUI lawyer immediately after police arrest you.
