How Does Having a Prior DUI Outside California Affect Your Case if Arrested in San Diego?
A DUI arrest in San Diego is stressful enough but if you already have a DUI conviction from another state, things can get even more complicated. California doesn’t treat prior DUIs from other states as separate or unrelated. In many cases, your out-of-state DUI can count as a “prior” and lead to harsher penalties for your current charge.
Here’s how it works, what the law says, and how an experienced San Diego DUI lawyer can help protect your rights.
California Recognizes Out-of-State DUI Convictions
Under California Vehicle Code § 23626 and the Interstate Driver License Compact (IDLC), California shares driver information with most other states. This means if you were convicted of DUI elsewhere, say, in Arizona, Nevada, or Texas, that record is usually accessible to California prosecutors and the DMV.
If the prior offense is considered “substantially similar” to a California DUI (meaning it involves driving under the influence of alcohol or drugs, or with a BAC of 0.08% or higher), it can be treated as a prior conviction under California law.
Why That Matters: Enhanced Penalties for “Multiple” DUIs
California imposes progressively tougher penalties for each DUI within a 10-year lookback period.
So if your out-of-state conviction occurred within the past 10 years and meets California’s definition of DUI, it can enhance your new charge.
For example:
- First-time DUI in CA: Up to 6 months in jail, license suspension, and fines around $2,000+
- Second-time DUI (including out-of-state prior): 96 hours to 1 year in jail, longer license suspension, mandatory DUI program up to 18 months, and higher fines
- Third or subsequent DUI: Possible felony charge, multi-year license revocation, and mandatory jail or prison time
In short, an out-of-state DUI can turn what would have been a “first-offense” case in San Diego into a repeat-offender situation with significantly higher stakes.
When an Out-of-State DUI May Not Count Against You
Not every prior conviction automatically qualifies. For California to treat your past DUI as a prior, the elements of the offense must be “substantially similar” to those under California law.
If the other state’s DUI statute differs, for example, if it criminalizes conduct California wouldn’t (such as having physical control of a parked car while intoxicated), your attorney may be able to challenge whether it should count.
Additionally, if the prior conviction was reduced, expunged, or legally flawed, it may not hold weight in California.
A skilled DUI defense lawyer can investigate the record, obtain certified court documents from the other state, and argue against the use of that prior to enhance your case.
The DMV Will Also Get Involved
Beyond the criminal court case, the California DMV conducts its own administrative action to suspend or restrict your license.
If you have an out-of-state DUI, California may honor the other state’s suspension through the Driver License Compact, which means:
- You may face a license hold or restriction in California even if you’ve already served a suspension elsewhere.
- You might have to complete a California-approved DUI program to reinstate your driving privileges.
Timing and communication with the DMV are critical here, your attorney can help ensure no unnecessary delays or double penalties occur.
