In Colorado, the police might pull you over and request that you take part in three field sobriety tests if they suspect you are driving under the influence. Bear in mind that this can happen even if you are sober. Each of these tests measures your reflexes, coordination and ability to think.
Horizontal gaze nystagmus
The first of the three standardized tests Colorado police officers use to gauge a driver’s impairment is the horizontal gaze nystagmus test (HGN). The HGN, which is also known as the eye test, measures one’s reflexes and ability to follow moving objects.
The officer starts by asking the person undergoing the test to follow the movements of an object, typically a flashlight or a pen, using only their eyes. This helps authorities check if the eyes jerk involuntarily, suggesting some degree of impairment.
Walk-and-turn
The walk-and-turn test checks a person’s motor skills and mental ability. This lets an officer determine if the driver is fit for the road.
To start, the driver must take nine steps forward in a line before pivoting and walking back. Each of these steps must be done heel-to-toe. All the while, they must count their steps aloud. This can determine their capability to balance themselves and follow instructions at the same time.
One-leg stand
Colorado officers use the one-leg stand test to check a person’s balance as well as their ability to determine when they are about to fall, potentially proving their mind is still sharp.
The driver must raise one foot at least six inches above the ground. They must keep their standing leg straight and count upwards from 1,000, all while looking at their elevated foot. This measures one’s balance, coordination and ability to follow instructions simultaneously.
What should you do if an officer pulls you over to do field sobriety tests?
If an officer pulls you over to determine whether or not you are sober, it is not against the law to refuse to take part in the tests. All three tests are voluntary, and refusal will not lead to a license suspension the same way refusing a breath test would.
Despite this, it is important to be cautious because refusing a field sobriety test can potentially arouse a police officer’s suspicion. Refusing the tests can also be used against you in court if authorities arrest you for DUI, even if you did not drink alcohol.
Ultimately, you have options in the event an officer makes a request. By politely refusing and asserting your rights, you can avoid taking the three field sobriety tests entirely.
