If you are facing a DUI charge, consulting a DUI defense lawyer is essential to understanding how these changes affect your case.
DUI Legal Limits in California – What's New?
The California Vehicle Code (CVC) specifies legal limits for blood alcohol concentration (BAC) based on driver type.
Under Section 23152, it is illegal to operate a vehicle with a BAC of:
- 0.08% or higher → For regular drivers
- 0.04% or higher → For commercial drivers & rideshare operators
- 0.01% or higher → For drivers under 21
The law now extends the 0.04% BAC limit to all passenger-for-hire drivers, including Uber, Lyft, and taxi operators. Previously, this limit only applied to commercial drivers.
Drivers found to be above these limits can face license suspension, fines, probation, or jail time, depending on prior convictions.
If you are a rideshare driver or commercial operator, the best DUI lawyer near me can help you understand how this rule applies to you and fight to protect your driving privileges.
Increased DUI Penalties for Repeat Offenders
California law takes repeat DUI offenses seriously. The 2025 DUI law changes focus on:
- Longer license suspensions for second-time and third-time offenders
- Mandatory alcohol education programs for all convicted drivers
- Stricter probation requirements, including ignition interlock devices (IID)
Third-time DUI offenders within 10 years will face a minimum jail sentence of 120 days, up from 90 days in previous years.
If you are a repeat offender, working with a lawyer for DUI near me can help reduce your penalties and explore options for alternative sentencing.
DUI Checkpoints and Law Enforcement Changes
Law enforcement officers continue to use DUI checkpoints to catch impaired drivers. Under California law, these checkpoints must:
- Be publicly announced ahead of time
- Be conducted in a fair and neutral manner
- Have a logical selection process for stopping vehicles
DUI checkpoints will now include expanded use of drug detection officers trained to identify marijuana and prescription drug impairment.
If you were stopped at a DUI checkpoint and believe your rights were violated, a DUI attorney can help you challenge the stop and evidence against you.
State-Mandated DUI Programs – Stricter Enforcement
Under California's DUI laws, individuals convicted of DUI must complete a state-approved DUI program before regaining their driving privileges.
DUI programs focus on:
- Alcohol & drug education courses
- Counseling & rehabilitation
- License reinstatement requirements
Stricter regulations have been placed on DUI program attendance. If a driver misses multiple sessions, they may be disqualified and required to restart the program from the beginning.
If you are facing DUI program requirements, a DUI defense lawyer near me can guide you through the process and help protect your rights.

- Illegal Traffic Stop – If police lack probable cause to pull you over, the evidence may be thrown out.
- Faulty BAC Testing – Breathalyzers must be calibrated and maintained properly. Errors in testing can result in false BAC readings.
- Medical Conditions – Some health conditions can mimic DUI symptoms, leading to wrongful arrests.
