In many places you can contest a traffic ticket by mail: plead not guilty, include a copy of the ticket, your written statement, and any evidence like photos, and mail it to the court before the deadline on the ticket. Send it with tracking or certified mail so you can prove it arrived. This is general information, not legal advice.
California lets drivers contest most traffic tickets entirely by mail under Vehicle Code section 40902, called a trial by written declaration. You submit a written statement and any evidence, and the officer submits theirs; a judge decides on the papers, with nobody appearing in court. Here is the part most people miss: if you lose, you can still request a brand-new trial in person, called a trial de novo, so the written declaration costs you nothing but the effort. Other states have their own versions, usually a not-guilty plea by mail followed by a mailed statement, but the exact procedure and forms differ, so check your court's website.
| Item | Why it matters |
|---|---|
| Your written statement, signed and dated | This is your testimony; keep it factual and short, one to two pages |
| A copy of the ticket | Ties your statement to the right case; never send your only original of anything |
| Photos, diagrams, or dashcam stills | Visual evidence is what wins written trials; label each exhibit |
| Witness statements | Signed, dated, with the witness's contact details |
| Bail or bond, if your court requires it | Many courts require you to post the fine amount up front with a written declaration; it is refunded if you win |
The bail requirement surprises people. Courts ask for it so that a loss can be settled immediately, and yes, you get it back if the ticket is dismissed. Check your court's instructions before mailing: sending a declaration without the required bail can get it rejected outright.
The date printed on the ticket is your deadline to respond, and courts treat it as hard. Mail your materials so they arrive well before that date; the court cares about receipt, not when you dropped it in a mailbox. This is exactly why tracking or certified mail matters: if the court says it never received your declaration, your receipt is your proof. Keep a complete copy of everything you sent, because courts do lose paperwork and you may need to resend.
You can still do most of the work by mail. Plead not guilty in writing before the deadline, which usually buys you a later court date, and mail any evidence or motions the court accepts in advance. Even where you must eventually appear, a mailed paper trail of your plea and evidence keeps you from scrambling at the last minute. Check the court's site for which forms accept mailed filing; traffic courts vary more than people expect.
LetterAgent prints letters on 8.5x11 paper, single-sided, and mails them with first-class postage or the fastest available non-express service, which suits a written statement or cover letter to a court. Two honest limits: courts often require specific forms, and LetterAgent prints your pages exactly as approved, so make sure the form is filled in correctly before you send it. And some filings need certified mail with a return receipt, which LetterAgent's standard service does not provide; for those, use the post office directly.
