Driving Under the Influence (DUI) Laws in California

Driving under the influence (DUI) of alcohol or drugs is a criminal offense in nearly every state, including California. Under California Vehicle Code 23152(a), it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher.

California imposes stricter BAC limits for certain drivers:

  • Commercial drivers: 0.04%

  • Drivers under 21: 0.01% (zero-tolerance law)

A DUI arrest can lead to criminal penalties, license suspension, increased insurance costs, and long-term damage to your record and career. The Hedding Law Firm is here to help. Schedule your consultation at (866) 986-2092 or contact us here. 

Why DUI Charges Are Taken So Seriously

Driving under the influence endangers not only the driver but everyone on the road. DUI cases often involve:

  • Traffic collisions

  • Serious bodily injury

  • Property damage

  • Fatal accidents

When injuries occur, DUI charges can escalate from misdemeanors to DUI felonies, resulting in prison time and permanent consequences.

Can a DUI Charge Be Reduced or Beaten?

Yes—but only with a realistic, evidence-based defense strategy. An experienced DUI attorney can:

  • Challenge the legality of the traffic stop

  • Expose flaws in field sobriety or breath testing

  • Contest chemical test reliability

  • Fight license suspension at the DMV

  • Negotiate reduced charges or dismissal when appropriate

There are no guarantees—but there are defenses when police or prosecutors cannot prove their case.

Penalties for a First-Time DUI in California

For a first DUI offense, penalties may include:

  • Up to 6 months in jail

  • $390–$1,000 in fines (plus penalty assessments)

  • 3–5 years of probation

  • 3-, 6-, or 9-month DUI school

  • License suspension

  • Possible alcohol monitoring (SCRAM bracelet)

Judges may also impose conditions such as no alcohol consumption while on probation.

What Happens if You Refuse a Breath or Blood Test?

Refusing a chemical test triggers automatic penalties, including:

  • One-year driver's license suspension

  • Presumption of DUI

  • Possible jail time

After a DUI arrest, police confiscate your license and notify the California Department of Motor Vehicles. You have 10 days to request a DMV hearing to challenge the suspension.

Will I Go to Jail for a Second DUI?

A second DUI conviction carries:

  • Minimum 96 hours in jail

  • Up to 1 year in custody

  • Longer DUI programs

  • Increased fines and penalties

However, in some cases, an attorney may negotiate a wet reckless plea to avoid mandatory jail time. When jail is unavoidable, it may be served in weekend custody or alternative programs.

Why Do Some DUI Cases Result in Jail or Prison?

Factors that increase jail exposure include:

If someone is injured, prosecutors may file a felony DUI under California Vehicle Code 23153(a), which carries mandatory jail or prison time.

The Truth About DUI Defense

We do not sell false hope. Every DUI case is evaluated only after reviewing:

  • Police reports

  • Test results

  • Video evidence

  • Prior history

If prosecutors cannot prove guilt beyond a reasonable doubt, the case should be dismissed or fought at trial. If the evidence is strong, the goal is to minimize damage through smart negotiation.

There is no magic defense—only common sense, experience, and knowing where the prosecution's case is weak.

A Step-by-Step Approach to Winning a DUI Case

A “win” looks different for every client:

  • Complete dismissal

  • Charge reduction

  • Avoiding jail

  • Saving a professional license

The key is hiring an attorney who will tell you the truth, identify your best outcome, and build a strategy to get there.

When Are Police Most Aggressive With DUI Arrests?

Law enforcement increases DUI enforcement:

  • On holidays

  • Late nights on weekends

  • After 10:00 p.m., especially after midnight

Officers often make questionable stops during these periods—stops that can be legally challenged by experienced DUI defense counsel.
