Can I contest a DOT fine in California?

Yes. In California, you have the right to contest DOT violations within 15 days of receiving the Notice of Violation (NOV). You can request an informal settlement conference with the FMCSA regional office, or request a formal hearing before an Administrative Law Judge. Many violations can be reduced 25-50% through the settlement process, especially for first-time offenders with good compliance records.

How long do DOT violations stay on my record in California?

DOT violations in California affect your CSA score for 24 months from the violation date. After 24 months, the violation no longer counts toward your SMS score, but it remains in the FMCSA inspection database indefinitely. Repeat violations within 24 months trigger higher fines and can lead to targeted inspections and compliance reviews.
