Washington Speed Limits

Speed limits are one of the most-tested topics on the WA permit exam, and the questions usually test Washington's statutory default limits -- what the speed is when no sign is posted. Under RCW 46.61.400, Washington's defaults are: 25 mph on city and town streets, 50 mph on county roads, and 60 mph on state highways. Local authorities may lower city and town streets in residential and business districts to 20 mph without an engineering study, and school zones are a statutory 20 mph during posted hours. Always obey the basic-speed law: never drive faster than is safe for current conditions, even under the posted or statutory limit.

Alcohol & BAC Limits

Expect at least one alcohol question on the Washington permit test. Memorize the three BAC thresholds: 0.08% is the legal limit for drivers age 21 and older, 0.04% is the limit for anyone driving with a commercial driver license (CDL), and Washington's threshold for drivers under 21 is 0.02% (RCW 46.61.503) -- a first violation in the 0.02%-0.07% range brings a 90-day license suspension, and 0.08% or higher brings full adult DUI charges. Washington also has an implied-consent law: by accepting your license, you have already agreed to a breath or blood test if an officer suspects you of impaired driving.

Right-of-Way Rules

Right-of-way is the single most-missed topic across every state's permit test. The rules are simple once you memorize them. At a 4-way stop, the first vehicle to fully stop goes first; if two arrive together, the driver on the right has the right of way. At an uncontrolled intersection, yield to any vehicle already in the intersection and to the driver on your right. At roundabouts, yield to traffic already circulating and enter only when there is a safe gap. Always yield to pedestrians in any crosswalk, marked or unmarked, and to emergency vehicles with lights and sirens — pull right and stop. When turning left across oncoming traffic, you must yield to oncoming vehicles. Yield does not give you the right of way; it requires you to give it up.

Following Distance & Safety

The Washington Driver Guide's rule: keep at least a 2-second gap behind the vehicle ahead at speeds above 30 mph, and increase that to about 4 seconds at lower speeds or when conditions call for it. Pick a fixed point on the road -- a sign, pole, or tree -- and count as the vehicle ahead of you passes it; if you reach the same point before you finish counting, you're following too closely. Increase the gap further in rain, fog, or when following large vehicles or motorcycles.

Road Sign Colors & Shapes

Road signs on the WA permit test follow the federal Manual on Uniform Traffic Control Devices, so shapes and colors are consistent across the country. Memorize the shapes first: octagon always means stop, downward triangle means yield, diamond means warning, pentagon marks a school zone, round warns of a railroad crossing, and horizontal rectangle is a guide sign. Then learn the colors: red is stop or prohibition, yellow is general warning, orange is construction, green is directions and exits, blue is driver services, brown is recreation, and fluorescent yellow-green is for schools and pedestrians. Practice identifying signs by shape and color alone — see the full visual cheat sheet on our Washington road-signs page.

Key Washington Numbers to Memorize

If you only remember a handful of facts going into the test, make it these. Every one of them maps to questions that have appeared on the real WA exam.

Parking Rules

Parking questions on the Washington permit test cover two patterns everywhere. For parallel parking, your wheels should be no more than 12 inches from the curb. For hill parking, the kerb rule decides which way your front wheels point: facing downhill (with or without a curb), turn the wheels toward the curb; facing uphill with a curb, turn the wheels away from the curb so they rest against it; facing uphill with no curb, turn the wheels toward the edge of the road. Always set the parking brake and leave the car in park (or in low gear with a manual).

Washington's no-parking zones (RCW 46.61.570) you must memorize: within 15 feet of a fire hydrant, within 20 feet of a crosswalk, within 30 feet on the approach to a flashing signal, stop sign, yield sign, or traffic control signal, and within 50 feet of the nearest rail at a railroad crossing.

GDL Restrictions (WA)

Washington's intermediate driver license (IDL) program: log 50 hours of supervised practice, including 10 hours at night, with a supervisor who is 21 or older and has held a license for at least 3 years. The IDL's night-driving curfew runs 1 a.m. to 5 a.m., with an exception if a parent, guardian, or licensed driver 25 or older is riding along. Passenger restrictions: no non-family passengers under 20 for the first 6 months, then no more than 3 for the second 6 months. Unlike most states, these restrictions lift after 12 months with a clean driving record -- no tickets or at-fault crashes -- rather than simply at age 18. Expect 1-3 GDL questions on the WA exam.

DUI & Drug Laws

DUI questions go beyond the BAC limits in Section 2. Three concepts you must know: implied consent means refusing a chemical test triggers automatic license suspension on top of any DUI charge. Prescription and over-the-counter drugs can also impair driving — antihistamines, sleep aids, painkillers, and some cold medicines list "do not operate heavy machinery" warnings, and driving impaired by them is a DUI even if you have a valid prescription. Marijuana — even where state-legal — is treated like alcohol for driving: any detectable impairment can result in a DUI, and edibles can take 1–3 hours to peak. The only safe BAC and the only safe THC level for driving is zero. There is no quick way to sober up; only time will lower your BAC.
