How California calculates speeding ticket fines

California speeding fines start with a base amount set by state law, then add a penalty assessment that can double or triple the total you owe. The base fine depends on how far over the limit you were driving. A ticket for going 1 to 15 miles per hour over the limit costs less than one for 26 miles per hour over. But the base fine is only the beginning — county penalty assessments, court costs, and traffic school fees stack on top.

The actual amount you pay depends on which county issued the ticket and whether you take traffic school. A $35 base fine in one county might become $250 total after assessments. In another county, the same violation could total $300. There is no single California speeding ticket cost because each county adds its own surcharges.

You cannot calculate your exact fine without knowing the county, your speed over the limit, and whether you plan to attend traffic school. But you can estimate the range and understand what makes the cost go up or down.

Key Takeaways

  • California base fines for speeding range from about $35 to $100 depending on how far over the limit you were, but penalty assessments typically double or triple the final amount.
  • County penalty assessments vary widely — the same violation can cost $100 more in one county than another because each county sets its own surcharges.
  • Traffic school costs $50 to $200 depending on the provider, but completing it may keep the ticket off your driving record and prevent insurance increases.
  • You must request traffic school before or at your court date, and you are only allowed to use it once every 18 months in California.
  • Contesting the ticket in traffic court is an option if you believe the officer made an error, but you will need to appear or submit a written statement.

Base fines by speed over the limit

California Vehicle Code Section 22349 sets the base fine amounts. For exceeding the speed limit by 1 to 15 miles per hour, the base fine is $35. From 16 to 25 miles per hour over, it jumps to $60. At 26 miles per hour or more over the limit, the base fine is $100. These are the numbers before any county adds its assessments.

The base fine is what appears on your citation under "Bail" or "Fine Amount." It is not what you actually pay. County assessments, court operations fees, and other surcharges are added by the court after the citation is processed. Some counties also add a "night court" fee if you were ticketed between 10 p.m. and 5 a.m.

If you were cited for speeding in a school zone or construction zone, the base fine doubles. A 1 to 15 mile per hour over violation in a school zone becomes a $70 base fine instead of $35. This doubled amount then gets the same county assessments added on top.

County penalty assessments and court costs

After the base fine, your county adds penalty assessments. These are mandatory surcharges that fund court operations, criminal justice programs, and emergency services. The assessment is usually calculated as a percentage of the base fine — often 200 to 300 percent. A $35 base fine might become $105 to $140 after the county assessment alone.

Some counties also add a separate "court operations assessment" and a "criminal conviction assessment." These vary by county and are not optional. Los Angeles County, for example, adds different assessments than Kern County or San Francisco County. You can find your county's specific assessment rates on the county court website or by calling the traffic court clerk.

The total before traffic school is typically 3 to 4 times the base fine. A $35 base fine often totals $100 to $150. A $100 base fine (for 26+ mph over) can total $300 to $400 depending on the county.

Traffic school costs and how it affects your total

Traffic school is optional but worth considering. The course costs $50 to $200 depending on the provider — online courses are usually cheaper than in-person classes. You pay the traffic school fee directly to the school, separate from your fine. You still owe the full fine amount to the court, but completing traffic school may keep the violation off your driving record.

The real benefit is not a lower fine — it is preventing your insurance company from seeing the ticket. If the violation does not appear on your record, your insurer cannot use it to raise your rates. Over three years, that can save you hundreds or thousands in premium increases. One ticket can raise your rate by 10 to 40 percent depending on your insurer and driving history.

You must request traffic school before your court date or at your first appearance. You cannot take it after you have already been convicted. You are also limited to one traffic school course every 18 months in California, so you cannot use it for multiple tickets in a short period.

When you can and cannot use traffic school

You are may be able to access for traffic school if you were cited for an infraction (not a misdemeanor), you were not in an accident that injured someone, and you have not used traffic school in the past 18 months. Most speeding tickets are infractions, so you usually may have access to. But if your speeding caused an accident or if you were cited for reckless driving instead of straightforward speeding, traffic school is not an option.

You must request traffic school before your court date. Some courts allow you to request it by mail or online. Others require you to appear in person or call the traffic court clerk. If you miss the important date to request it, you lose the option. Once you are convicted without requesting traffic school, you cannot go back and take it later.

If the court approves your traffic school request, you will have 90 days to complete the course. You then submit proof of completion to the court. The court dismisses the ticket, and it does not appear on your driving record. Your insurance company will not see it.

Contesting the ticket in traffic court

You have the right to contest the ticket. You can request a trial and argue that the officer made an error in measuring your speed, that road conditions made the posted limit unsafe, or that the radar or laser gun was not properly calibrated. You do not need a lawyer, though you can hire one if you choose.

You can appear in person or submit a written statement to the court. Some courts allow you to request a trial by written declaration, meaning you write your version of events and the officer responds in writing — no in-person appearance needed. If you lose, you still owe the full fine. If you win, the ticket is dismissed and you owe nothing.

The officer must appear at your trial to testify. If the officer does not show up, the ticket is usually dismissed. But do not count on this — most officers appear for traffic trials. You will need to explain specifically why the citation was wrong, not just argue that you were not speeding.

Payment plans and hardship options

If you cannot pay the full amount at once, you can request a payment plan. Most California courts allow you to pay in installments over 12 months. You will need to contact the traffic court clerk and explain your situation. Some courts charge a small fee for setting up a payment plan.

If you are experiencing financial hardship, you can request a fine reduction or a "time payment plan" with no interest. You will need to fill out a form and provide proof of your income. The judge has discretion to reduce the fine if you demonstrate genuine hardship. This is not automatic, but it is worth requesting if you cannot afford the full amount.

If you do not pay or appear in court, the court can suspend your driver's license and refer the debt to a collection agency. Unpaid traffic fines can also prevent you from renewing your vehicle registration.

Frequently Asked Questions

How much does a speeding ticket cost in California on average?

Most speeding tickets in California total between $150 and $300 after base fines and county assessments are combined. Tickets for going 26+ mph over the limit can exceed $400. The exact amount depends on your county, how far over the limit you were, and whether you were in a school or construction zone.

Can I lower my speeding ticket fine?

You can request a fine reduction by submitting a hardship form to the court and proving financial difficulty. The judge may reduce the amount. You can also contest the ticket in court if you believe the officer made an error. Traffic school does not lower the fine but prevents it from affecting your insurance rates.

What happens if I ignore a speeding ticket in California?

If you do not pay or appear in court, the court will suspend your driver's license and may refer the debt to a collection agency. You will not be able to renew your vehicle registration. The fine can also grow if late fees are added.

Can I take traffic school more than once?

No. California law limits you to one traffic school course every 18 months. If you have already used traffic school in the past 18 months, you cannot use it again for a new ticket. You would need to either pay the fine or contest the ticket in court.

Do I have to go to court for a speeding ticket?

You can handle most speeding tickets by mail or online without appearing in court. You can pay the fine, request traffic school, or request a trial by written declaration. You only need to appear in person if you choose to contest the ticket in a live trial or if the court requires it.
