Traffic school masks a DMV point while leaving the conviction on the record for insurers to find. A dismissed Trial by Written Declaration leaves no conviction at all. Here is how the two options compare across cost, time, insurance impact, and eligibility.
Two Paths That Reach Very Different Places
When a California driver receives a one-point moving violation, two options are commonly available beyond simply paying the fine: traffic school and Trial by Written Declaration. Both involve the same court, the same citation, and the same underlying fine amount — but the process and potential outcomes are fundamentally different.
What Traffic School Does
California's traffic violator school (TVS) program allows eligible drivers to complete a DMV-approved course in exchange for the court masking the DMV point associated with the conviction. The conviction itself is not removed. It remains on the court record and is accessible to insurance companies when they pull a full driving history. What traffic school masks is the point — specifically, it prevents the point from counting toward the DMV's Negligent Operator Treatment System thresholds.
Whether insurance underwriters treat a masked conviction differently from an unmasked one depends on the insurer. Some insurers apply no surcharge when traffic school is completed. Others apply the same treatment regardless of traffic school. The conviction remains visible either way.
Traffic school is available only for eligible one-point infractions. Drivers are limited to one traffic school election per 18-month period, measured from violation date to violation date. CDL holders operating a commercial motor vehicle are not eligible. For speeding more than 25 mph over the limit, a court clerk cannot grant traffic school; only a judicial officer (a judge or commissioner) can allow it (California Rules of Court, rule 4.104). Courts retain some discretion to deny traffic school even for otherwise eligible violations.
What Trial by Written Declaration Does
Trial by Written Declaration under CVC 40902 is a contest — not an acceptance. Instead of allowing the conviction to be entered and masking its effects, the driver submits a written account to the court describing their version of events. The citing officer is asked to send a written statement too. Our complete guide to trial by written declaration in California covers who can use it, form TR-205 and the bail deposit.
If the court determines that the violation was not proved, the citation is dismissed. If the officer does not send one by the date the court sets, the judge decides the case on the evidence the court has, which can include the citation itself. The case may be dismissed, but that is the judge's decision and no result is guaranteed. A dismissal means no conviction enters the record, no DMV point is added, and the bail deposit is returned in full. The outcome is categorically different from a traffic school result — there is nothing on the record for an insurer to find.
TBWD is not risk-free. If the court finds the driver guilty, the conviction and DMV points are the same as paying, and the bail deposit is applied to the fine, but the judge can set a fine higher or lower than the bail. Contesting does not make a driver ineligible for traffic school, but after a guilty finding it is up to the judge. If the driver disagrees with the decision, most courts allow a Trial de Novo — an in-person hearing — if requested within 20 calendar days after the court mails its decision. Courts that offer online trial by declaration through MyCitations do not allow one; the driver can appeal instead. Contesting does not by itself use the driver's 18-month traffic school eligibility window; the window is used only if traffic school is granted.
Side-by-Side Comparison
| Factor | Traffic School | Trial by Written Declaration |
|---|---|---|
| Possible result | Point masked; conviction remains on record | Citation may be dismissed (the judge decides); if dismissed, no conviction, no point |
| Insurance record impact | Conviction visible to insurers | No conviction if dismissed; same conviction as paying if found guilty |
| Cost beyond the fine itself | ~$52 court admin fee + $25–75 course fee | Bail deposit up front (refunded if dismissed); if found guilty, the fine is up to the judge |
| Time involved | 4–8 hours of coursework | Preparing declaration + 8–12 weeks for a decision |
| Uses 18-month traffic school window | Yes | Only if traffic school is granted after a guilty finding |
| Available to CDL holders in a CMV | No | Yes (for eligible infraction citations) |
| Available for AB 645 speed camera notices | No (no point to mask) | No (contested with the city that issued the notice) |
| If found guilty | Not applicable (no trial) | Same conviction and points as paying; the judge can set a fine above or below the bail |
Factors Drivers Often Consider
Drivers considering traffic school often note whether they have already elected traffic school for a citation within the last 18 months, when time constraints make preparing and filing a declaration impractical, or when the driver has already accepted the conviction and wants to limit its point impact on the DMV record.
Drivers considering a Trial by Written Declaration often note whether they are eligible for both options and what a dismissal or a conviction would mean for their record. Which option to choose is the driver's decision. Contesting does not by itself use the traffic school window, which may matter if the driver has a history of violations.
