Do Standardized Field Sobriety Tests Accurately Assess a Driver’s Mental and Physical Impairment?

During a California DUI detection process, the officer screens (or tests) a driver prior to making an arrest decision.

The pre-arrest screening phase starts out with the administration of the standardized field sobriety tests. These tests are said to be designed to assess a driver’s mental and physical impairment.

The three most commonly used field sobriety tests are:

  1. horizontal gaze nystagmus
  2. walk and turn test
  3. one-leg stand test

The walk and turn test and one-leg stand test are considered to be divided-attention tests, requiring concentration on multiple tasks. These tasks are designed to simulate the same physical and mental tasks that are required for a person to safely drive a vehicle.

A knowledgeable and experienced Southern California criminal defense attorney at Wallin & Klarich understands the apparent disconnect between a walk and turn test or one-leg stand test and a driver’s ability to safely operate a vehicle. Our attorneys know how to deal with police allegations of poor performance or failure of field sobriety tests.
