Warning signs — Maryland Permit Test
Warning signs on the Maryland permit test — 17 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A stop sign is ahead, often hidden by a curve or a hill. Slow down and be ready to stop.
A hidden stop sign is the one people run, so the warning arrives while there is still distance to slow.
A traffic signal is ahead, often where you cannot see it in time. Slow down and be ready to stop.
A signal after a curve or a hill gives no warning of its own, so the sign does it instead.
Traffic from another roadway merges with yours ahead. Adjust your speed and position to let it in.
Merging traffic has to join at speed, and knowing it is coming lets you make the gap before they need it.
The right lane ends ahead. Merge into the through lane before it does.
Lanes end at a fixed point whether or not anyone has merged, so the sign is the cue to do it early.
A roundabout is ahead. Slow down and prepare to yield to traffic already circulating.
A roundabout reverses the usual priority — traffic already circling goes first — so it is worth knowing before you arrive.
A crossroad intersection is ahead. Watch for traffic entering from either side.
A crossroad means traffic can appear from both sides at once, which is a different scan from a T-intersection.
A sharp turn in the direction shown is ahead. Slow down before you reach it.
A sharp turn is one you cannot take at road speed, so the warning exists to make you slow before the geometry does it for you.
The bridge ahead is narrower than the road. Slow down and watch for oncoming traffic.
A narrow bridge removes the margin either side, so two vehicles that would pass easily on the road may not on it.
A divided highway begins ahead. Keep to the right of the median.
A divided highway begins where the oncoming lanes move away, and the sign marks the point you must be on the right of the median.
The road ahead carries traffic in both directions. Do not pass where you cannot see far enough ahead.
Coming off a one-way or divided stretch, the lane beside you stops being yours — and the sign is the warning that it has.
A steep downgrade is ahead. Shift to a lower gear and do not ride the brakes.
The sign warns of a descent long enough to cook brakes that are ridden all the way down, so you can pick a lower gear before it starts.
A bump or rough patch is in the road ahead. Slow down.
A bump at speed can lift a wheel off the road, which costs you both steering and braking.
The road ahead is slippery when wet. Slow down and avoid sudden braking or steering.
A road that is fine when dry can be treacherous when wet, and the sign marks where that difference is greatest.
Bicyclists may be riding in or crossing the road ahead. Slow down and give them room.
Cyclists here are crossing or joining your path, and they are small enough to be missed in a routine glance.
Deer regularly cross the road here. Slow down, especially at dawn and dusk.
Deer travel in groups, so the one that crossed in front of you is rarely the last.
An advisory speed is the safe speed for the condition ahead, such as a curve or a ramp. It is a recommendation, not the posted limit.
The advisory speed is the engineer's estimate for the curve or ramp ahead, which is usually well below the posted limit.
Road work is ahead. Slow down, expect workers and equipment, and obey work-zone speed limits.
Work zones change layout without warning, so the sign buys the distance to read what has changed.
On the test
What does this sign mean?
A stop sign is ahead. A hidden stop sign is the one people run, so the warning arrives while there is still distance to slow.
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.
Where these come from
Every rule here is checked against Maryland Driver's Manual, published by the Maryland Department of Transportation Motor Vehicle Administration, and against the state code itself. Last checked 2026-08-29.
