Should you refuse or consent to field sobriety tests if you are stopped by the CHP under suspicion of driving under the influence? There is no simple answer and it depends on the circumstances. If you are stopped in San Francisco County, call The Law Offices of Michael L. Davidson in San Mateo at 866-719-9678 to discuss how to proceed if you are stopped.
Refusing Sobriety Tests, Yes or No?
We have all seen the tests that the CHP performs as part of their battery of field sobriety tests. There is walking the line, heal to toe, and balance testing. The question of whether you volunteer to take them is up to you. We would recommend that if you are intoxicated, it is best to refuse them. If you are not intoxicated, taking the field sobriety test might be the quickest resolution to the situation.
If you politely refuse the field sobriety tests there are both benefits and risks. The police have no evidence of drunken behavior, but the prosecutor has the right to argue that the reason you refused was because you were intoxicated. It is similar to running from the scene of the crime--there is a presumption of guilt.
As for field breath tests and preliminary alcohol screening, it is best to refuse them under most circumstances. The exception is if the breathalyzer is an E-pass machine. Because it functions in court as an evidencing breath test, refusal in this instance will cost you your license. In other cases, the arresting officer has a duty to advise you that the field breath test is not an official test, and you have the right to refuse it although they often overlook this duty.
