Warning signs — Washington Permit Test
Warning signs on the Washington permit test — 14 rules, each with the reason behind it and a question on it while it is fresh.
The rules
This sign recommends a speed change for a hazard or road condition ahead, often a curve or a turn.
The number is what the bend was measured at, and it assumes nothing has made the surface worse.
These signs indicate that a speed change is recommended for a potential hazard or road condition (often a curve or turn).
This sign marks the entrance to a roundabout, which can also carry yield, pedestrian warning, and directional arrow signs.
Knowing one is coming is what lets you pick a lane before you are already in it.
These signs mark the entrance to a roundabout. Roundabouts can also have yield, pedestrian warning, and directional arrow signs.
This sign warns of a place where animals cross the road.
One animal crossing usually means more behind it, so slowing down matters after the first has gone.
Deer crossing
This sign warns that the surface ahead loses grip when it is wet.
Bridges and painted surfaces give up their grip before the rest of the road does.
Slippery when wet
This sign warns that a traffic signal is coming, often where you cannot see it in time.
It is posted on fast roads and over crests, where the light appears too late to stop for.
Signal ahead
This sign warns that the road ahead carries traffic in both directions.
It appears where a divided road ends, and the lane beside you stops being yours.
Two-way traffic
This sign marks a place where schoolchildren cross the road.
Children misjudge how fast a car is coming, and they are short enough to disappear behind a parked van.
School crossing
This sign marks a place where people on foot cross the road.
It is placed where somebody steps out between intersections, which is where a driver is least ready.
Pedestrian crossing
This sign warns of a sharp turn in the road ahead.
A sharp turn is the one a driver carries too much speed into, and the sign comes before the point of no return.
Sharp turn
This sign warns of a steep grade in the road ahead.
A long grade is where a loaded truck crawls and where brakes get hot enough to stop working.
Hill
This sign warns that traffic is about to join from another lane.
Both lanes keep going, so neither driver is required to stop, and that is what makes it awkward.
Merge
This sign warns that a road crosses the one you are on.
It is the warning that a vehicle can come from either side, at a place with nothing else controlling it.
Cross road
This sign marks the start of a stretch where passing is not allowed.
It is posted where the road ahead hides whatever is coming, and passing there is a bet on an empty lane.
No passing zone
This sign warns that a stop is coming before you can see it.
It is placed where the stop is hidden by a crest or a bend, so you can slow before you find it.
Stop ahead
On the test
What does this sign tell a driver about the road ahead?
A speed change is advised for what is coming. The number is what the bend was measured at, and it assumes nothing has made the surface worse. Washington State Driver Guide, p.115: “These signs indicate that a speed change is recommended for a potential hazard or road condition (often a curve or turn).”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
What it costs
- One payment, once — not a subscription. Nothing renews and there is nothing to cancel, for an exam you sit one time.
- Free to start: a 10-question test and the first section of cards. No sign-up and no account.
- Paying opens the rest of the cards, unlimited full-length practice tests, and retests built from exactly the questions you got wrong.
- Every level up to Prepared — 3 tests passed in a row.
- Do the work, fail the real exam, and we refund you.
