Answer: Octagon
STOP signs are always the eight-sided octagon shape, so they are recognizable even from behind.
Road Signs
Answer: 25 mph
Washington's statutory default for city and town streets is 25 mph unless a different limit is posted (RCW 46.61.400).
Speed & Spacing
Answer: 30 minutes after sunset to 30 minutes before sunrise, or anytime rain, snow, fog, or smoke reduces visibility
Washington requires headlights from 30 minutes after sunset to 30 minutes before sunrise, and any time rain, snow, fog, or smoke is present.
WA Laws
Answer: 15 years
The minimum age is 15 (or 15 years, 6 months if you have not enrolled in an approved driver-training course before turning 18).
Teen & Permit Rules
Answer: Move over a full lane if you can
With 2 or more lanes your direction, move over a full lane to pass a bicyclist.
Sharing the Road
Answer: School zone or school crossing
The pentagon shape is reserved for school-zone and school-crossing signs.
Road Signs
Answer: 50 mph
County roads default to 50 mph absent a posted sign.
Speed & Spacing

A dashed yellow centerline on your side permits passing when it is safe.

Official Washington Driver Guide (dol.wa.gov, full PDF text-extracted), and Revised Code of Washington sections RCW 46.61.400 (speed defaults), 46.61.212 (Move Over/emergency zone), 46.61.500 (reckless driving), 46.61.688 (seat belts), 46.61.672 (personal electronic device use), 46.61.687 (child restraint), 46.20.308 (Implied Consent), and 46.65.020/46.65.070 (Habitual Traffic Offender designation and revocation) — researched and verified 2026-08-18. Exam format (40 questions, 80%/32 correct, unified pool with no separate sign section) officially confirmed on dol.wa.gov. The `points` category deliberately centers on the well-sourced Habitual Traffic Offender mechanism rather than a demerit-point table, because Washington does not use points against driving privileges. It also deliberately avoids asserting a specific numeric threshold for a separate, lower-tier "too many tickets" suspension under RCW 46.20.291(3): two official DOL pages gave conflicting numbers (one said 6 violations/12 months or 7/24 months, another said 3/12 or 4/24) and the statute itself is discretionary with no numeric threshold in its text, so that figure could not be resolved from official sources and was excluded rather than guessed. Known gaps deliberately NOT invented: exact dollar fine amounts for seat belt, handheld-phone, and child-restraint violations (set by court fee schedule, page inaccessible); the meaning of blue and green parking curb colors (only white, yellow, and red are confirmed for Washington); funeral procession right-of-way rules (not addressed anywhere in the Driver Guide); specific truck/bus no-zone footage figures (described only qualitatively); a specific numeric following-distance figure behind a moving emergency vehicle (the Guide states vehicles must yield but gives no "X feet" rule, unlike some other states); and a standard passenger-car stopping-distance table (only a loaded-truck example and general headlight-glow guidance were found). Re-verify periodically, as the Driver Guide, fees, and thresholds change over time.
