Q: What are the key components of a DUI investigation that I should be aware of?

A:

In California, a DUI investigation typically consists of several key components. First, it often begins with an officer observing erratic driving behaviors, such as swerving, speeding, or making illegal turns. This initial observation can lead to a traffic stop. Once stopped, the officer will look for signs of impairment during their initial assessment of the driver, which may include the driver’s appearance, behavior, and responses to questions.

If the officer suspects that the driver is under the influence, they may conduct field sobriety tests (FSTs). These tests are designed to assess the driver’s coordination, balance, and ability to respond to instructions. Common field sobriety tests include the Horizontal Gaze Nystagmus test, the Walk-and-Turn test, and the One-Leg Stand test. The results of these tests provide the officer with further evidence to determine whether the driver is impaired.

Another critical component is the breath or blood test. If an officer believes a driver is DUI, they may request a chemical test to measure blood alcohol concentration (BAC). In California, implied consent laws mean that if you refuse to take a chemical test after being lawfully arrested, you may face additional penalties, such as a license suspension. It’s essential for drivers to be aware of their rights during this process, including the right to consult with an attorney before agreeing to any tests.
