Arrested for DUI in Orange County with a previous conviction on your record? Prior offenses can sharply increase penalties and even turn a misdemeanor into a felony. California’s 10-year look-back rule (VC § 23550) links court and DMV records to calculate repeat-offense penalties. At Braden & Tucci, we review every alleged prior for accuracy and procedural flaws to reduce or remove its influence on your current case.
Understanding California’s 10-Year Look-Back Rule
Under VC § 23550, any DUI within 10 years of a new arrest counts as a prior. The window runs from arrest-to-arrest, not conviction date. This statute applies statewide and includes wet-reckless convictions that stemmed from alcohol-related arrests. Once verified, priors increase mandatory minimum jail and license penalties.

How Priors Affect Sentencing
- Second Offense: 10 days jail minimum + 2-year license suspension.
- Third Offense: 120 days jail + 30-month DUI program + 3-year revocation.
- Fourth Offense (Felony): 16 months to 3 years state prison and 4-year revocation.
These tiers illustrate how dramatically prior DUIs raise exposure. Our defense approach targets the chain of prior convictions, lab accuracy, and record validation to negotiate reduced counts or charges.
DMV and Court Record Linkage
The DMV maintains a 10-year driving record for alcohol offenses and automatically notifies courts when a new arrest occurs. This can extend license suspensions and increase IID requirements. Our team reviews DMV data for mistakes such as mismatched dates or duplicate entries, which often lead to incorrect “repeat offender” status.

Defenses Against Prior Conviction Influence
- Procedural Challenges: Missing Miranda warnings, improper testing, or plea irregularities in the prior case.
- Age of Prior: If the arrest date is over 10 years old, it cannot be used to enhance sentencing.
- Out-of-State Comparison: The foreign statute must be “substantially similar” to California’s DUI law to qualify as a prior.
Our 2,000 + DMV hearing record includes numerous cases where challenging a prior reduced a felony to a misdemeanor or shortened license revocation.
Long-Term Consequences of Repeat DUIs
Multiple convictions can raise insurance premiums, restrict professional licenses, and limit employment or travel. Felony status adds firearm and voting restrictions. We help clients pursue record relief and expungement where eligible after probation.
Case Example: Reducing a Felony to a Misdemeanor
In one recent Orange County case, our team proved that an alleged 2012 DUI was filed beyond the 10-year window. The court dismissed the felony count and reduced it to a misdemeanor, avoiding prison and preserving the client’s license.
Frequently Asked Questions
What if my prior is over 10 years old?
It cannot be used for enhancement under VC § 23550. An attorney verifies the dates and files to remove it from consideration.
Do out-of-state DUIs count as priors in California?
Yes if the foreign law is equivalent to California’s DUI statute; otherwise, your attorney can argue it should not apply.
Can an expunged DUI still count as a prior?
Yes—expungement does not erase a DUI for enhancement purposes, but it may help with employment and licensing.
How do priors affect license suspension length?
Each additional DUI extends the suspension period: 2 years for a second, 3 for a third, and 4 for a felony fourth offense.
The Bottom Line
Prior DUI convictions can heavily impact new charges in California—but many enhancements can be challenged or removed. At Braden & Tucci, our focused DUI practice identifies errors and defends against repeat-offender penalties with precision and empathy.
