DUI

What is a DUI?

A "DUI" is operating a motor vehicle with a blood alcohol content over that is over the legal limit, or while under the influence of alcohol, drugs, or both.

Blood Alcohol Content (BAC) %

It is illegal to operate a motor vehicle with a blood alcohol concentration ("BAC") of:

  • 0.08% or higher― 21 years old or older operating a regular passenger vehicle;
  • 0.04% or higher―operating a commercial vehicle;
  • 0.01% or higher―younger than 21 years old.

"Under the Influence"

Under the influence means that one’s mental or physical abilities are so impaired that he or she is no longer able to drive a vehicle with the caution of a sober person, using ordinary care, under similar circumstances.

DUI Penalties

The punishments for a DUI include a suspended driver's license, over $1,500 in fines, 3 years of probation, a mark on your DMV and criminal records, at least 3 months of classes, and fees for classes.

Additional Penalties

Penalties may also include jail time, continuous alcohol monitoring (SCRAM), installation of an ignition interlock device in your vehicle, impoundment of your vehicle, and community service. You will likely be required to abstain from alcohol and to obtain an SR-22 insurance policy.

The severity of the punishment depends on the facts of your case, including Blood Alcohol Content % (BAC), prior DUI convictions, whether an accident, injury, or fatality occurred, and whether you left the scene of the accident.

Loss of Driver's License

In California, law enforcement officers may take your license if they suspect you are driving under the influence. Your license will be suspended if you fail to contact the DMV within 10 days to schedule a hearing.

DUI Defenses

If law enforcement fails to follow proper procedures, the defendant was not driving the vehicle, or was not intoxicated at the time of driving, it is a defense to DUI charges.

Police Procedures

Law enforcement must have probable cause to believe a person is driving under the influence before conducting an arrest. In addition, they must follow specific procedures for seizing a driver's license, administering breathalyzer and blood tests, and maintaining and calibrating devices.

Under the Legal Limit

When a breathlyzer or blood test was properly conducted within three hours of driving, it is presumed that the test accurately measured the driver's blood alcohol content. In that case, the defendant must prove that their blood alcohol content was actually under the legal limit.

Under the Influence

There is no bright line for what it means to be "under the influence." Instead, the test is based on all facts, including whether the driver admitted to being under the influence, the pattern of driving, and the results of field sobriety tests.

Less Common Defenses

If you were not the driver, had no choice but to drive while intoxicated to protect your safety, or were drugged without your consent, it is a defense to driving under the influence. However, these defenses are difficult to prove and therefore are rarely used.

Reduced Charges

In some cases, the district attorney will offer to resovle a DUI case in exchange for a guilty or no contest plea to wet or dry and reckless charges. This can happen when there is a significant technical flaw in the prosecution's case or the blood alcohol level is at or below the legal limit.

What is the difference between "Wet" and "Dry"?

  1. A wet and reckless is considered a prior DUI for court and DMV purposes. If you receive a subsequent DUI conviction it will be treated as your second DUI.
  2. A wet and reckless involves the use of drugs, alcohol, or both. The prosecutor must file a statement with the court describing how drugs or alcohol were involved in the offense.

Dry and Reckless (Vehicle Code Section 23103)

"Dry and reckless" is defined as driving on public roads with disregard for the safety of persons or property.

Wet and Reckless (Vehicle Code Section 23103.5)

"Wet and reckless" is defined as driving on public roads with disregard for the safety of persons or property where drugs or alcohol is involved in the offense.

Prescription Drug DUI

There is no red line for prescription drug impairment, unlike like the .08% BAC cut-off for alcohol. Therefore, you could be convicted of DUI with any amount of prescription drugs in your blood. Having a valid prescription and using the prescribed dosage are not a defense to a drug-related DUI.

Marijuana DUI

Although recreational marijuana is now legal in California, it is still illegal to drive under the influence of marijuana. Drivers who fail sobriety tests and are in possession of marijuana are often arrested for DUI and requested to submit to a drug test. A person who regularly uses marijuana, or used it within a few days of driving, will likely test positive and be charged with driving under the influence.
