I know some people who have been arrested for DUI here in Alameda, California and some of them claim that they are innocent. How would a police officer claim that a driver is under the influence?

In a DUI investigation in Alameda, California, the police officer usually claims that the DUI suspect “performed poorly” or “failed” the field sobriety tests and the handheld breath test indicates that the driver’s blood alcohol level was above the legal limit. Based on this, the officer would “form an opinion” that the driver is under the influence or the driver’s ability to drive a motor vehicle safely is impaired. After this, the officer would arrest the driver and take him/her to the police station (or hospital) for a chemical test.

The driver suspected for DUI would choose between a breath test and a blood test. The state of California has an “Implied Consent Law” that says that a person who is arrested lawfully for DUI should submit to one of these tests. A refusal could subject the DUI suspect to stiffer court penalties and possibly a one-year (or longer) driver’s license suspension. If the driver chooses a blood test, the blood sample would be forwarded to a crime lab for analysis. If he/she chooses a breath test, the officer would see the blood alcohol content reading immediately after the driver blows twice into the breath test machine. The officer sometimes tells the DUI suspect of the result, sometimes not.
