Field Sobriety Tests in Las Vegas

DUI field sobriety tests (FSTs) are utilized by law enforcers in Nevada to determine whether an individual is under the influence of alcohols or drugs. Failing these tests will lead officers to believe that your diminished mental and physical faculties resulted from consuming alcohol or drugs.

If a police officer stops you for DUI suspicion in Las Vegas, Nevada, you might be asked to perform field sobriety tests. These tests are actually optional but the arresting officer doesn’t normally claim it to be so. Of course, there are consequences for your refusal as well as this might make it look like you are really using drugs or have been drinking and might submit you for full evidentiary testing.

It is legal to politely reject a field sobriety test. These tests check your agility and are designed to see whether or not you can take control of yourself without failing. A person who is not under the influence of controlled substances and alcohol will find it very easy to pass this kind of test.

Different Types of Field Sobriety Tests

Nevada has several standard sobriety test procedures that police officers themselves employ. The officers can also create their own test as long as it follows strict procedures that don’t violate a person’s rights.

Here is a brief list of the common sobriety tests used:

• Walk and Turn – Walking with heel to toe for nine steps, a turn, and nine (9) steps back. The officer is looking for:
• Unsteady balance
• Falling
• How much the arms are used for balance
• How well the suspect follows instructions.
• One Leg Stand - In this test, the driver will balance on one leg and count numbers or say the alphabet. The test is supposed to measure the driver’s ability to do two tasks at the same time. The officer is looking for:
• Swaying
• Hopping
• Using arms for balance
• Putting the foot down
• Correctly counting numbers, or accurately reciting the alphabet.
• The Pen Test, or HGN - Is also known as the “Nystagmus Test.” This test measures whether the eyes bounce when they are all the way to the left or the right. Historically, if someone fail this test, it is highly likely they have a BAC of .10 or above.
• Stand With Feet Together and Tip the Head Backwards – This test will measure the driver’s balance.
• Count the Number of Fingers the Officer Raises – This test is supposed to measure vision, and determine if it is blurry or not.
• Rhomberg Stationary Balance Test – In this test, the driver stands with his feet together, and leans his head back to look up at the sky while holding out his arms to the side. This test measures balance.
• Finger to Nose – This test requires the driver to close his eyes and touch his nose with his finger. This test measure coordination and balance.

Other tests may also be performed like breath, blood and urine tests. These are administered once you are arrested for alleged DUI. There’s no need to submit to a field sobriety test though but remember that refusal to do it might trigger even more suspicion.

The Role of the National Highway Traffic Safety Administration in Field Sobriety Tests

The protocols that police officers use in administering DUI field sobriety tests are issued by the National Highway Traffic Safety Administration (NHTSA). This federal agency has concluded that the three FSTs Walk-and-Turn, HGN and One-Leg Stand are enough to accurately determine a driver’s ability to maneuver their vehicle safely.

However, there are several factors in this conclusion that are very important in DUI defense:

1. The NHTSA provides training on how to administer these three FSTs correctly yet only a few officers have received this.
2. The best accuracy rates of these tests are only 65 to 77%.
3. Other factors unrelated to alcoholic intoxication can affect the results of the tests, such as poor lighting, bad weather, fatigue, nerves, intimidation, sickness, injury, or even unsecure footwear.
