Washington traffic stops end in one of two very different documents, and the one in your hand sets the court, the deadline, the cost and whether counsel is worth paying for.

Two drivers pulled over on the same stretch of Aurora Avenue, ten minutes apart, can walk away holding pieces of paper that have almost nothing in common. One is a notice of infraction: a civil matter, resolved with money and a mark on a driving record, with no possibility of jail. The other is a criminal citation, which is the opening move in a misdemeanor or gross misdemeanor prosecution and carries a mandatory court date, a potential jail sentence, and a criminal record that follows a person through background checks. The paper looks similar. Read the top line and the box that says whether a court appearance is required.
Speeding, failure to yield, following too closely, expired tabs, and the vast majority of what officers write in Washington are civil infractions. There is no arrest, no jail exposure, and no right to appointed counsel, because the state is not accusing anyone of a crime. The response deadline is short and unforgiving: fifteen days from the date the notice was issued, delivered in writing to the court named on the citation. Miss it and the court can enter a default finding, add a late penalty, and refer the matter to a collection agency, and the Department of Licensing can suspend a license for failure to respond.
The visible cost is the monetary penalty, typically somewhere between a hundred and a few hundred dollars depending on the violation and the speed. The invisible cost is the entry on the abstract, which insurers price against, employers with driving requirements read, and the Department of Licensing counts toward suspension. That second cost usually dwarfs the first, and it is the reason people contest tickets they could easily afford to pay. Three options exist on the response form: pay it, request a contested hearing, or request a mitigation hearing, where the violation is admitted and only the penalty is argued.
Driving under the influence, reckless driving, negligent driving in the first degree, driving while license suspended or revoked, hit and run, and racing are crimes in Washington, not infractions. Most are gross misdemeanors, punishable by up to 364 days in jail and a fine in the thousands, and DUI carries mandatory minimums that scale with breath test results and prior offenses. The citation will name an arraignment date, and appearing on that date is not optional; failure to appear produces a bench warrant. The National Highway Traffic Safety Administration is the federal body responsible for impaired driving policy nationally, but the charge itself is filed and prosecuted locally.
Driving while license suspended in the third degree deserves its own mention, because it is the charge people are most surprised to receive. It frequently begins as an unpaid infraction that went to collections, triggered a suspension notice mailed to a stale address, and then produced a criminal charge at the next routine stop. That sequence is the clearest illustration of why the civil deadline matters. A hundred and fifty dollar ticket ignored in March becomes a criminal case, a defense bill, and a possible jail exposure by autumn, and the fix at that stage costs many times what the fix at the beginning would have.
Infractions and misdemeanors are both heard in courts of limited jurisdiction, meaning municipal courts inside city limits and district courts elsewhere in the county. Seattle Municipal Court handles what Seattle police write inside the city; a stop by the State Patrol on I-5 or a county road heads to a King County District Court division. The practical differences are large: filing practices, prosecutor discretion, whether deferred findings and diversion-style resolutions are routinely available, and how a particular bench treats declaration-only contested hearings. Two identical citations in two adjacent jurisdictions can resolve very differently, which is what local knowledge is actually buying.
That is the honest frame for the money question. On a first infraction with a clean abstract, many people handle mitigation themselves and come out fine, because the downside is bounded and the process is designed for self-represented drivers. On a criminal charge, or on an infraction that would trigger suspension under the accumulation rules, the arithmetic flips, and hiring a Seattle Traffic Attorney starts to look cheap next to a suspended license, a job that requires driving, or an insurance surcharge running for three to five years. Criminal defendants who cannot afford counsel can ask the court to appoint a public defender at arraignment.
Read the citation for three things: the court named on it, the deadline or appearance date, and whether the offense is labeled an infraction or a crime. Write the deadline somewhere you will see it, because the fifteen day window runs from issuance and not from the day the mail catches up with you. If it is criminal, the arraignment date is the deadline, and contacting counsel before that date is worth more than contacting counsel after it. If it is civil, requesting a hearing preserves every option, costs nothing beyond the request, and buys months of time to decide what to do.
Everything downstream (the fee you pay, the record you carry, whether the Department of Licensing ever gets involved) follows from that first reading. Spend ten minutes on it before you spend anything else.
