DUI & Drug Arrests

In Marin County, it is illegal to drive under the influence of drugs or alcohol. According to California law, a person can be arrested for DUI if he or she is driving while impaired by drugs or alcohol OR driving with a blood alcohol concentration of 0.08% or higher.

Police may suspect that a person is impaired by alcohol or drugs if he or she is engaged in unusual driving behaviors. These unusual behaviors may include swerving, speeding, making irregular stops, and disobeying traffic signals. If law enforcement notices these behaviors, they will most likely make a traffic stop. It is important to remember that a traffic stop is not the same thing as an arrest.

During the traffic stop, the police officer will examine the driver for further signs of intoxication, such as slurred speech, bloodshot eyes, flushed face, inability to answer questions, or open containers in the driver’s vehicle. If the officer concludes that the driver may be under the influence of drugs or alcohol, he or she will ask the driver to step out of the vehicle for further analysis.

Once the driver has stepped out of the vehicle, the officer will ask him or her to perform three standardized field sobriety tests. At this point, the officer may or may not inform the driver that the field sobriety tests are voluntary. Due to the inaccuracy of most field sobriety test results, it is usually in the driver’s best interest to refuse to perform the tests.

The officer will also ask the person to submit to a breath alcohol test. This test is also voluntary; however, if a person refuses to take the breath test, his or her driver’s license will automatically be suspended. If a person consents to the breath alcohol test and it reveals a BAC of 0.08% or higher, California law considers that person to be intoxicated.

If there is sufficient probable cause after a period of observation, the officer may decide to place the driver under arrest. During the arrest, the officer will read the driver his or her Miranda Rights. If the officer fails to do so, anything the driver says before or after the arrest may not be admissible in court.

If you have been arrested for DUI in Marin County, it is important that you contact a skilled attorney immediately. A DUI attorney can represent you in court and ensure your rights are protected throughout the legal process.
