Sign shapes — Maryland Permit Test
Sign shapes on the Maryland permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
An octagon (eight-sided) sign always means stop: come to a complete stop at the stop line, before the crosswalk, or before entering the intersection.
A rolling stop hides what a full stop reveals: cross traffic and pedestrians you cannot properly see while still moving.
A downward-pointing triangle means yield: slow down and give the right-of-way to traffic and pedestrians.
Yield asks you to fit into the other road's traffic rather than interrupt it, so you may have to stop but often will not.
A pennant-shaped sign on the left side of the road marks the beginning of a no-passing zone.
The pennant sits on the left because that is the side you would pull into, and it marks where passing stops being legal.
A pentagon (five-sided) sign marks a school zone or school crossing.
The shape is unique to schools so it reads as children even before you can make out the picture.
A round sign warns of a railroad crossing ahead.
The advance sign gives you distance to slow down before the crossing itself, which may be around a bend.
A crossbuck (X-shaped) sign marks the railroad crossing itself and requires drivers to yield to trains.
A crossbuck marks the crossing itself; trains cannot stop or steer, so the duty to yield is always yours.
Diamond-shaped yellow signs warn of hazards or changes in road conditions ahead, such as curves, intersections, or merges.
Diamond and yellow together mean the road is about to do something you cannot yet see.
On the test
What does this sign mean?
stop completely at the line, crosswalk, or intersection. A rolling stop hides what a full stop reveals: cross traffic and pedestrians you cannot properly see while still moving.
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.
