Washington Road Signs and Their Meanings

You could read the Washington Driver Guide from cover to cover and still not know how long the knowledge test is. The exam has a numbered section of its own — 1.12, Personal Driver License Exams — and the guide spends it on the sequence rather than on the arithmetic: there are two exams, you must pass the Driving Knowledge Exam before you may take the Driving Skills Exam, and once the knowledge exam is behind you, you have two years in which to complete the skills exam. What that section never gives, and what nearly two hundred pages on roads, drivers and vehicles never give either, is the question count or the passing score. Those live somewhere else entirely — on the Department of Licensing's own website, where the requirement is stated in one line: you must get 32 out of 40 correct answers to pass. Signs are part of what those 40 cover, and the guide is where the state expects you to learn them.

Ask Washington where to sit the knowledge exam and the guide answers twice. Section 1.12 lists both routes under Taking the exams: find a driver training school exam location by searching approved driver training school at dol.wa.gov, or schedule an appointment at a driver licensing office in License Express. What the Department of Licensing will not tell you is the price. You will need to pay a fee that varies by location, it says, and to check with your testing location for the exact amount. Language carries the same caveat: the knowledge test is available in twelve languages and the driver guide is published as a PDF in seventeen, but the DOL still tells you to check with your driver training school that they offer the test in the language you need. The scoring is the part that does not move — thirty-two of forty correct on the knowledge test, and at least 80 out of 100 on the drive test, which is graded separately and whose result lasts a year. Neither figure is broken down by subject. Washington has never said how many of the forty questions are about signs, and it publishes no minimum number of sign answers.

In the guide, signs are section 4.12, sitting inside the chapter on roads between traffic light signals at 4.11 and common intersections at 4.13. It opens with a color table of eight entries — red for a prohibitive or restricted action, orange for construction and maintenance warning, yellow for general and unexpected road conditions, fluorescent yellow green for school, pedestrian and bicycling activity, white for regulatory, green for guide or directional information, blue for motorist services guidance, brown for public recreation, cultural and historical areas. Then it stops and admits that the list is incomplete. Some, but not all, Washington State signs are shown below, section 4.12 says, and adds that you are responsible for knowing all signs, including city and county signs. The signs it does show make the state obvious from the page alone — chain advisory, light rail, national forest, tsunami hazard zone, volcano evacuation route.

Most of the published Washington questions here describe a sign instead of naming it. You are given the color, the shape and whatever is printed or drawn on the face — a yellow diamond carrying a tractor, a round yellow sign with a black X and two R letters, a blue sign showing a fork and knife — and asked what it means. That is deliberate, and it follows the half of the guide's signs section that actually teaches: the common signs block pairs every picture with a short explanation. The block beside it runs the other way. Other traffic signs is a caption grid — a picture, a name, nothing else — which tells you what a sign is called but not what it requires of you, and being able to name a sign is not what the exam is testing. Describing the face and asking for the meaning is also the situation the exam is standing in for, since no sign on a Washington road arrives with its name attached. One published question reaches outside the signs section for its source — the reflective triangle carried by farm vehicles, which the guide explains where it explains how to share a road with them. Every other one here is cited to the guide's sign material.

34 published Washington road-sign questions, each with an explanation and a citation to the handbook section it came from.
