When must you dim your high beams in Washington, and how far away does an oncoming car need to be? Washington law specifies exact distances for dimming, and the 500/300-foot rule is one of the most tested questions on the exam.
| Rule | Detail |
|---|---|
| When to use headlights | From sunset to sunrise, and any time visibility is less than 500 feet due to rain, fog, snow, or dust |
| When conditions require headlights | Washington: use headlights when it is dark, rainy, snowy, foggy, or smoky, the manual lists all these specifically |
| High beams, when to use | On open roads with no oncoming traffic and no vehicle directly ahead; increases visibility up to 500 feet |
| Dim to low beams, oncoming traffic | Switch to low beams when within 500 feet of an oncoming vehicle |
| Dim to low beams, following | Switch to low beams when within 300 feet of a vehicle you are following |
| Low beams in fog | Always use low beams in fog, high beams reflect off fog and reduce your visibility |
| Parking lights only | Not a substitute for headlights, illegal to drive using parking lights only |
Key test point: The 500-foot / 300-foot rule is a classic exam question. Oncoming = 500 feet. Following = 300 feet. Dim accordingly.
What does "overdriving your headlights" mean in Washington, and why is it dangerous? Driving at night significantly increases crash risk; these rules cover visibility, speed, and wildlife hazards specific to Washington roads.
| Rule | Detail |
|---|---|
| Stopping distance at night | Washingtons manual states: at 55 mph it takes 450 feet to stop, well beyond typical low-beam range. Reduce speed at night and in poor visibility. Dim within 300 feet of vehicles you are following. |
| Reduce speed at night | Even at the posted limit, reduced visibility means you need more time to react, slow down |
| Increase following distance | Use a minimum 4-second following distance at night instead of the standard 3 seconds |
| Watch for pedestrians & cyclists | They are much harder to see at night, especially away from lit areas |
| Avoid looking directly at oncoming lights | Look toward the right edge of the road to avoid being blinded by oncoming high beams |
| Wildlife in Washington | Deer and elk are active along US-2, US-12, SR-20, and eastern Washington highways especially at dawn and dusk in fall. The Columbia Basin (I-90 east of the Cascades) has open range, animals can wander onto the highway. Reduce speed when animal crossing signs are posted. |
| Keep windshield clean | A dirty windshield causes glare at night and significantly reduces visibility |
Is it legal to use your phone while driving in Washington, and can a cop pull you over just for texting? Washington has specific primary-enforcement laws targeting handheld device use, with stricter rules for permit and intermediate license holders.
| Rule | Detail |
|---|---|
| Complete handheld ban | Washington: cannot hold any electronic device while driving, all drivers, all ages; fines doubled after first violation |
| Handheld cell phone use | Illegal for drivers with a learners permit or intermediate license (under 18). Adults 18+ may use handheld devices but texting remains banned. |
| School zones, cell phones | All handheld cell phone use is prohibited in active school zones regardless of driver age |
| Penalty, first offense | Fine up to $250 |
| Penalty, subsequent offenses | Fine up to $500 |
| Other distractions | Eating, grooming, adjusting GPS, or anything that takes your eyes off the road can be cited as inattentive driving |
| Hands-free use | Bluetooth and hands-free devices are legal and recommended for all drivers |
Key test point: Texting while driving is a primary offense in Washington, police do not need another reason to pull you over. This distinction frequently appears on the knowledge exam.
How far from the tracks must you stop at a railroad crossing in Washington, and what vehicles must always stop even when no train is coming? Railroad crossing rules are tested on the Washington knowledge exam; know exactly when to stop and how far back.
| Rule | Detail |
|---|---|
| When to stop | Stop when lights are flashing, gates are lowering or down, a train is visible or audible, or a flagman signals you to stop |
| How far back to stop | At least 15 feet from the nearest rail, never stop on the tracks |
| When to proceed | Only after the train has completely passed, lights have stopped flashing, and gates are fully raised |
| Multiple tracks | After one train passes, check for a second train on adjacent tracks before proceeding |
| Never race a train | Trains cannot stop quickly, a freight train at 55 mph takes over a mile to stop. Never try to beat a train. |
| Stalled vehicle on tracks | Get everyone out immediately and move away from the tracks at an angle in the direction the train is coming from |
| Parking near crossings | Do not park within 50 feet of a railroad crossing |
Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.
Washington has been adding roundabouts across the state, particularly in Spokane, the Eastside suburbs of Seattle, Bellingham, and along SR-16 and US-12 upgrades. The DOL test covers them. Entering traffic yields to vehicles already circulating inside.
| Rule | Detail |
|---|---|
| Who has right-of-way | Vehicles already inside the roundabout always have right-of-way. Entering drivers must yield. |
| Direction of travel | Always travel counterclockwise (to the right) around the central island |
| Entering a roundabout | Slow down, yield to circulating traffic, and enter when there is a safe gap |
| Lane selection, single lane | Follow the directional signs and road markings for your intended exit |
| Lane selection, multi-lane | Choose your lane before entering based on your exit: right lane for right/straight exits, left lane for left turns or U-turns |
| Do not stop inside | Never stop inside a roundabout unless to avoid a collision, keep moving at a slow, steady speed |
| Large vehicles | Trucks and buses may use the mountable apron (raised inner ring) to navigate, give them extra space |
| Pedestrians & cyclists | Yield to pedestrians in crosswalks when entering and exiting. Watch for cyclists who may ride through the roundabout. |
Key test point: The most common wrong answer on roundabout questions is thinking you have right-of-way when entering. You never do, yield to traffic already inside.
"The AI mock tests were surprisingly realistic. The explanations for road signs helped me understand the logic, not just memorize. Passed my permit test on the first try!"
