How to Fight a Traffic Ticket in California: The Complete 2025 Defense Guide

Getting a traffic ticket in California doesn’t mean you’re stuck paying it. The truth is, most drivers don’t realize they have powerful legal rights to contest citations—and with the right strategy, you can often get your ticket completely dismissed.

This guide breaks down everything you need to know about fighting California traffic tickets in 2025, from Trial by Written Declaration (your secret weapon) to traffic school and negotiation strategies.

👉 Bottom line: Fighting your ticket is almost always worth it. Even if you don’t win, you still protect your right to traffic school, which saves you thousands in insurance hikes. And if you want the strongest chance of dismissal, ClerkHero can prepare a winning defense for you.

Your Legal Rights When Fighting Traffic Tickets

California law gives you multiple ways to fight back:

• Trial by Written Declaration (TR-205) - You submit your defense in writing, and the officer must also respond. If they don’t, your case is dismissed automatically.
• Trial de Novo - If you lose the written declaration, you can still request an in-person trial for a second chance.
• Traffic School - Even if you lose, you can often attend traffic school to keep insurance companies from seeing the violation.

Key fact: Paying a ticket outright = pleading guilty. That guilty plea adds points to your DMV record, spikes your insurance, and can even affect employment.

The 4 Main Ways to Fight a California Traffic Ticket

1. Trial by Written Declaration (Highest Success Rate)

Trial by Written Declaration is hands down the most effective option, with dismissal rates as high as 79–100% for certain violations.

How it works:

1. Submit Form TR-205 and bail payment before your ticket’s due date.
2. Write a clear, factual defense statement.
3. The citing officer must also submit their own written statement.
4. A judge reviews both and makes a decision.

Why it works: Officers often don’t bother filing their paperwork. If that happens, your case is dismissed, and you get your bail refunded.

Typical success rates:

• Speeding in construction zones: 100%
• Basic speed law (VC 22350): 92%
• Red light violations: 85%
• Stop sign violations: 79%

2. In-Person Court Trial

If you want to fight face-to-face, you can request a trial in court.

Advantages:

• You can cross-examine the officer.
• Present evidence and witnesses in person.
• No upfront bail payment required.

Best for cases involving:

• Witnesses who can back your story.
• Equipment malfunctions (radar, lidar).
• Emergencies or unusual circumstances.
• Complex disputes where credibility matters.

3. Traffic School (Insurance Protection)

If dismissal doesn’t happen, traffic school is your next best move.

What it does: Keeps the violation off your insurance record while still requiring you to pay the fine.

Eligibility requirements:

• Valid CA license (non-commercial).
• One-point moving violation.
• Haven’t done traffic school in the past 18 months.
• Not 25+ mph over the speed limit.
• No alcohol or drug involvement.

Costs:

• Court fee: $52
• Course: $15–45
• Total: $67–97

Savings: On average, drivers save $3,500+ in insurance hikes over 3 years.

4. Negotiate for Reduced Charges

Some courts allow negotiation (plea bargaining).

Possible outcomes:

• Speeding → reduced to equipment violation.
• Moving violation → reduced to parking ticket.
• Lower fines in exchange for court fees.
• Community service instead of paying.

2025 Updates: New Laws Impacting Tickets

• Speed Cameras: Rolling out in 7 cities. Tickets range from $50–500. Defenses often involve calibration and maintenance records.
• Daylighting Law: You can’t park within 20 feet of a crosswalk. Many tickets will hinge on unclear signage—ripe for defense.
• Plate Obstruction Law (AB 2111): New restrictions on reflective coatings, but also new grounds for manufacturer defect defenses.

---

What NOT to Do

• Don’t pay online if you plan to fight—it counts as pleading guilty.
• Don’t miss deadlines—21 days is the standard response time.
• Don’t write excuses in your defense. Stick to facts.
• Don’t ignore the ticket—that triggers extra $100+ fees and possible warrants.
