Field Sobriety Tests in California: Can You Refuse and What Are the Consequences?

If you’ve ever been pulled over on suspicion of a DUI in California, you’ve likely heard of field sobriety tests (FSTs). These are the physical and mental exercises that police officers use to determine if a driver is impaired. But are these tests accurate? And are you required to take them? This article will explore the truth about FSTs and your rights when it comes to these roadside evaluations. For more information, you can visit https://tunglaw.com/pasadena-dui-lawyer/.

What Are Field Sobriety Tests?

The National Highway Traffic Safety Administration (NHTSA) has standardized three FSTs that are used by law enforcement across the country:

  • The Horizontal Gaze Nystagmus (HGN) Test: This test involves the officer moving an object, such as a pen or a flashlight, back and forth in front of your eyes. The officer is looking for an involuntary jerking of the eyes, which can be a sign of alcohol impairment.
  • The Walk-and-Turn Test: This test requires you to walk nine steps, heel-to-toe, in a straight line, turn on one foot, and then walk back nine steps. The officer is looking for signs of impairment such as losing your balance, starting before the instructions are finished, or using your arms to balance.
  • The One-Leg Stand Test: This test requires you to stand on one foot, with the other foot raised about six inches off the ground, and count aloud for 30 seconds. The officer is looking for signs of impairment such as swaying, hopping, or putting your foot down.

While these tests are standardized, their accuracy is a subject of much debate. The NHTSA claims that these tests are highly accurate when administered correctly, but many factors can affect their reliability.

Are Field Sobriety Tests Accurate?

The accuracy of FSTs can be affected by a number of factors, including:

  • Medical Conditions: Certain medical conditions, such as inner ear problems, back injuries, or neurological disorders, can make it difficult to perform these tests.
  • Fatigue: If you are tired, you may have difficulty with your balance and coordination, even if you are not impaired.
  • Nervousness: Being pulled over by a police officer can be a nerve-wracking experience, and your anxiety can affect your performance on these tests.
  • Improper Administration: If the officer does not administer the tests correctly, the results can be unreliable.

Can You Refuse to Take Field Sobriety Tests?

In California, you have the right to refuse to take FSTs. Unlike chemical tests (breath or blood tests), which are mandatory under the state’s implied consent law, FSTs are voluntary. The officer is required to inform you that these tests are voluntary, but they may not always do so clearly.

If you refuse to take the FSTs, the officer may still arrest you based on other evidence, such as the smell of alcohol on your breath or your performance during the traffic stop. However, your refusal to take the FSTs cannot be used against you in court.

What Are the Consequences of Refusing?

While there are no legal penalties for refusing to take FSTs, there may be some practical consequences. The officer may be more likely to arrest you if you refuse, as they may interpret your refusal as a sign of guilt. However, it’s important to remember that the results of these tests can be used as evidence against you in court, so refusing to take them may be in your best interest if you believe you will not perform well.

Understanding your rights when it comes to field sobriety tests is a critical part of protecting yourself during a DUI stop. If you are facing a DUI charge, an experienced attorney can help you challenge the results of these tests and build a strong defense on your behalf. Don’t let unreliable evidence determine your future. Know your rights and get the legal help you need.
