A traffic stop involving suspected impairment can escalate quickly, especially when a police officer asks you to perform roadside tests. Driving under the influence (DUI) is a serious offense in Virginia. If you are suspected of being under the influence, you will likely be asked to perform field sobriety tests or breathalyzer tests.
The legal obligations surrounding field sobriety tests and breath tests depend on the type of test requested and the timing of the request. There are differences between the two tests, and it is important to know your rights if ever in such a situation, and what happens after you are arrested.
What’s the Difference Between Field Sobriety Tests and Breath Tests?
Law enforcement officers typically rely on two categories of testing when investigating a potential DUI. While both are intended to assess impairment, they serve different purposes and carry different legal consequences.
Field sobriety tests are physical or cognitive exercises used to observe coordination, balance, and attention. These may include walking heel to toe, standing on one leg, or following an object with your eyes. The results are based largely on an officer’s observations and judgment. Factors such as fatigue, uneven pavement, injuries, age, or anxiety can affect performance, even when no alcohol or drugs are involved.
Breath tests measure the amount of alcohol in a person’s breath to estimate blood alcohol concentration. Officers may request a preliminary breath test at the roadside or administer an official breath test after an arrest. These tests are treated differently under Virginia law, particularly once implied consent applies. If you take a breath test, you need a Virginia DUI lawyer who understands how these tests are performed, the science behind them, and how to challenge the validity of the BAC results.
Are You Required to Take a Field Sobriety Test in Virginia?
Virginia drivers are not legally required to take field sobriety tests. These roadside exercises are voluntary, and refusing to participate is not a criminal offense. A polite refusal does not result in fines, points, or an automatic license suspension.
However, refusal does not prevent an officer from continuing a DUI investigation. Arrest decisions may still be based on driving behavior, physical observations, or statements made during the stop. Choosing not to perform field sobriety tests can limit subjective evidence, but it does not guarantee that charges will not follow.
Can You Refuse a Breath Test?
The answer depends on when the test is requested. Roadside breath tests, often used before an arrest, are generally voluntary. Refusing does not carry immediate legal penalties. These tests are often used to help officers determine whether probable cause exists. However, your refusal can be used as evidence against you in a DUI case.
Once a driver is lawfully arrested for DUI, Virginia’s implied consent law applies. At that point, drivers are required to submit to a chemical test of their breath or blood. Refusing a post-arrest test can result in serious consequences, even if the DUI charge itself is later challenged.
How Refusal May Affect Your Case
Refusing certain tests can limit the evidence available to the prosecution, but it does not make a case disappear. Courts may still be informed of a refusal, and prosecutors may argue that it reflects a consciousness of guilt. Whether refusal helps or hurts depends on the circumstances of the stop and how the case is handled afterward.
A first refusal constitutes a civil offense and may result in a one-year license suspension. If there are prior DUI convictions or refusals, penalties can increase and may include additional suspension time or jail.
This is where guidance from a traffic attorney in Chesterfield, VA, is crucial in cases like DUI/DWI. An attorney can review whether the stop was lawful, whether probable cause existed, and whether testing procedures followed legal standards.
