Everything important from the Washington Driver Guide — organized for the exam
Memorize these numbers first. Washington DOL test questions are frequently built around specific distances, speeds, BAC levels, and time periods. These come up constantly.
Road signs are tested heavily. Know each sign's shape, color, and meaning. The real test often shows a sign description and asks what it means.
| Shape | Meaning | Example |
|---|---|---|
| Octagon (8-sided) | STOP — always and only | Stop sign |
| Triangle (pointing down) | YIELD — give right of way | Yield sign |
| Diamond | WARNING — hazard ahead | Curve, pedestrian, deer |
| Pentagon (5-sided) | SCHOOL ZONE | School crossing |
| Pennant (triangle right) | NO PASSING ZONE | No-passing pennant |
| Round (circle) | RAILROAD CROSSING advance warning | RR crossing sign |
| Rectangle (vertical) | REGULATORY — rules you must follow | Speed limit, turn restrictions |
| Rectangle (horizontal) | GUIDE or INFORMATION | Street name, mile marker |
| X-shaped crossbuck | RAILROAD CROSSING — treat like yield | Railroad crossbuck |
| Color | Category | What It Means |
|---|---|---|
| Red | Regulatory — STOP / PROHIBIT | Stop, yield, do not enter, wrong way, no-turn circles |
| Yellow | WARNING | General hazard warnings — curves, hills, intersections, animals |
| Orange | WORK ZONE / CONSTRUCTION | Construction ahead, road crew, slow down. In Washington, fines are doubled for offenses committed in construction areas when workers are present (Section 4.12). |
| Green | GUIDE / DIRECTIONAL | Highway exits, distances, direction, mile markers |
| Blue | SERVICES | Gas, food, lodging, hospital, rest area |
| Brown | RECREATION / CULTURAL | Parks, campgrounds, historical sites, scenic areas |
| White | REGULATORY | Speed limits, lane rules, turn restrictions |
| Fluorescent Yellow-Green | WARNING — pedestrian / school / bike | School zones, crosswalks, bike lanes |
| Fluorescent Pink | INCIDENT MANAGEMENT | Crash clean-up, debris removal, temporary traffic control |
Right of way is the #1 failure topic on the DOL knowledge test. Master every scenario below — these questions will be on your exam.
| Signal | What You Must Do |
|---|---|
| Solid GREEN | Proceed — but yield to traffic already in intersection |
| Solid YELLOW | Prepare to stop if safe; proceed only if stopping would be dangerous |
| Solid RED | Stop completely; may turn right on red after stop and yield (unless posted) |
| GREEN ARROW | Protected turn — oncoming traffic must stop. You may turn in the arrow's direction, but still yield to vehicles and pedestrians already in the intersection. |
| YELLOW ARROW | Protected turn is ending — prepare to yield or stop |
| Flashing YELLOW ARROW | Unprotected turn — you MAY turn but MUST yield to oncoming and pedestrians |
| Flashing RED | Treat exactly like a STOP sign — stop, yield, proceed when safe |
| Flashing YELLOW | Caution — slow down and proceed carefully. Do not need to stop. |
| RED + GREEN ARROW | Stop for through traffic; turn in direction of arrow only |
| Signal NOT working | Treat as ALL-WAY STOP — all traffic stops |
DUI questions appear on virtually every DOL knowledge test. Know the BAC levels, implied consent law, and penalties. Washington uses the term "DUI" (Driving Under the Influence).
| Situation | Consequence |
|---|---|
| BAC of 0.08%+ (driver 21+) | DUI under RCW 46.61.502. Convictions can suspend driving privileges 90 days to 4 years, plus heavy fines, jail, ignition interlock, mandatory alcohol assessment, and a probationary license (Section 1.15). |
| Impairment below the legal BAC limit | Yes — Washington can charge DUI when alcohol or drugs impair your ability to drive, even with a BAC below 0.08%. DUI also applies to any driver in physical control of a parked vehicle (RCW 46.61.503). Polydrug use is the most common impairment in fatal crashes (Section 3.1). |
| Test refusal (implied consent) | Under RCW 46.20.308, every Washington driver agrees to be tested if an officer suspects DUI. Refusing the breath or blood test costs your driving privilege 90 to 730 days, or until age 21 — whichever is longer (Section 1.15). |
| BAC — under 21 (Zero Tolerance) | Drivers under 21 face the same DUI consequences at 0.02% BAC or above, and at any detectable active THC above 0 ng/mL. Minors with an alcohol, drug, or firearm offense risk having their license delayed until age 17 (Section 1.15). |
| CDL / commercial driver BAC | Commercial drivers must follow stricter rules and CDL endorsement requirements. Learn more by searching commercial driver licenses at dol.wa.gov (Section 1.10). |
| DUI — causing death or injury | Vehicular homicide and vehicular assault are felony charges in Washington that can permanently revoke driving privileges, in addition to prison time and heavy fines. Alcohol- and drug-related offenses appear on your driving record for life (Section 1.15). |
School bus rules are heavily tested. All vehicles in BOTH directions must stop on a 2-lane road when a school bus has flashing red lights. Exception: opposing traffic on a road with 3+ lanes separated by a median or barrier. Fines are doubled (Section 4.2).
| Location | Minimum Clearance |
|---|---|
| Fire hydrant | 15 ft — do not park within 15 ft of a fire hydrant (Section 4.18) |
| Stop sign / yield sign / flashing signal / traffic control device | 30 ft — do not park within 30 ft of these (Section 4.18) |
| Pedestrian safety zone | 20 ft — do not park within 20 ft of pedestrian safety zones (Section 4.18) |
| Crosswalk at intersection | Never on it — never park on a crosswalk, sidewalk, or bicycle lane (Section 4.18) |
| Railroad crossing | 50 ft — do not park within 50 ft of a railroad crossing (Section 4.18) |
| Fire station driveway | 75 ft on the opposite side of the street. Also no parking within 5 ft of any driveway, alley, or private road (Section 4.18) |
| Driveway entrance (public or private) | Not in front of — always prohibited |
| Accessible (handicapped) space | Never without valid placard/plate — keep the white striped access aisle clear; don't hang the placard from the rearview mirror while driving (Section 4.18) |
| Inside an intersection or on a crosswalk | Never — always illegal |
| Bridge, overpass, or tunnel | Never — also no parking on a freeway shoulder unless you have an emergency (Section 4.18) |
| No Stopping zone | Never stop here, for any reason |
| No Parking zone | No parking — may stop to load/unload |
The rule: always turn wheels so that if the car rolls, it rolls away from traffic or is caught by the curb.
| Situation | Turn Wheels | Why |
|---|---|---|
| Facing DOWNHILL, WITH curb | RIGHT (into curb) | Car rolls into curb and stops |
| Facing DOWNHILL, NO curb | RIGHT (away from road) | Car rolls away from traffic |
| Facing UPHILL, WITH curb | LEFT (away from curb) | Car rolls back, caught by curb |
| Facing UPHILL, NO curb | RIGHT (away from road) | Car rolls away from traffic |
GDL questions appear on many tests. Know Washington's Graduated Driver Licensing program, the restrictions in each phase, and the specific ages, hold periods, and curfew hours.
| Equipment | Requirement |
|---|---|
| Headlights (on) | Required from 30 min after sunset to 30 min before sunrise, and any time it's dark, rainy, snowy, foggy, or smoky. Daytime running lights aren't as bright as headlights and don't activate taillights (Section 2.5). |
| High beams (dim) | Switch back to regular headlights when 500 ft in front of an oncoming vehicle, and 300 ft when following another vehicle. Use low beams in fog, heavy rain, sleet, snow, or dust (Section 2.5). |
| Horn | Use when needed to prevent a crash. Do NOT use to express anger, greet friends, or encourage others to move. Avoid around blind pedestrians and animal-drawn vehicles. |
| Turn signals | Signal at least 100 feet before you make your move. Make sure your signal stops blinking after the turn (Section 2.5). |
| Tinted windows | Tinting must not obstruct the driver's view. Don't hang things from the mirror or clutter windows with decals or items that block your view (Section 2.5). |
| TVs / video screens visible to driver | Prohibited while vehicle is in motion (navigation is typically excepted — confirm against Washington manual). |
| Muffler | Must prevent excessive or unusual noise |
| Brakes | Vehicles must have working service brakes capable of stopping under control. Parking brake required. Test brakes lightly after driving through deep water to dry them out. |
| Wipers | Must adequately clean the windshield when used |
| Tail lights / rear reflector | Tail lights and rear reflectors are required equipment on all vehicles. Keep lenses clean for night-driving visibility. |
| Tires | Tire condition and tread composition directly affect stopping distance. Proper inflation and good tread are critical. |
| Hazard lights | For use when parked/stopped in an emergency — not while driving normally |
| Seat belts & child restraints | Every person in a moving vehicle must wear a seat belt or be in an approved child restraint (RCW 46.61.687, RCW 46.61.688). Children up to age 2: rear-facing. Ages 2-4: harness car seat. Ages 4+: booster until lap-and-shoulder belt fits (typically 4'9"). Children under 13 should not ride in the front (Section 2.6). |
