Signs by picture — Maryland Permit Test
Signs by picture on the Maryland permit test — 12 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The sign that tells a driver they are not allowed to enter a road is one of the rectangular regulatory signs, which regulate traffic and must be obeyed.
The paper shows you the signs and asks you to pick; the words on the card are not on the test.
Do Not Enter
The sign that tells a driver they are traveling against traffic is one of the rectangular regulatory signs, which regulate traffic and must be obeyed.
You will see it a moment after missing the first warning, so it has to be known by sight.
Wrong Way
The sign posted on a one-way road means traffic can only go in the direction of the arrow.
Turning onto a one-way street the wrong way puts you head-on with everyone on it.
Traffic can only go in the direction of the arrow.
The sign that tells a driver to stay to the right of a median is one of the rectangular regulatory signs, which regulate traffic and must be obeyed.
The median is coming either way; the sign settles which side of it you pass.
Stay to the Right of Median
The sign that forbids turning around to go back the way you came is one of the rectangular regulatory signs, which regulate traffic and must be obeyed.
A U-turn where one is banned is made across traffic that has no reason to expect it.
No U-Turn
The sign that forbids turning at a red light, where a turn on red would otherwise be allowed, is one of the rectangular regulatory signs.
It is posted where the corner is blind or busy enough that a turn on red would meet someone.
No Turn on Red
A driver must make a complete stop at the stop line at the sign that requires a stop, and if there is no stop line, before entering a crosswalk.
It is the one sign the paper will always show, and the one shape used for nothing else.
You must make a complete stop at the stop line. • If there is no stop line, stop before entering a crosswalk.
At the sign that means yield, a driver slows down, looks to the left and the right, and yields to pedestrians, bicycles, and vehicles.
Yielding is deciding early that the other driver goes first, which is what stops two of you deciding at once.
Slow down as you come to a yield sign. Look to the left and the right. Yield to pedestrians, bicycles, and vehicles.
The sign that warns of two roads merging is a warning sign, which gives notice of a situation that might not be readily apparent.
Merging traffic arrives from the side you are not looking at, which is why the warning comes first.
Two Roads Merging
The sign that warns the road is slippery when wet is a warning sign, which gives notice of a situation that might not be readily apparent.
The road looks the same wet or dry; the sign is how you know before the car tells you.
Slippery When Wet
The round railroad warning sign is used to warn that there is a railroad crossing ahead.
The train cannot stop for you, so the warning has to reach you well before the tracks.
Round: Railroad Warning Used to warn that there is a railroad crossing ahead.
The five-sided pentagon shape warns you of school zones and marks school crossings.
Children step off a curb without looking; the shape tells you to be the one who is looking.
Pentagon: School Zone and School Crossing The pentagon (five-sided) shape warns you of school zones and marks school crossings.
On the test
Which of these signs tells a driver they are not allowed to enter?
The DO NOT ENTER sign. The paper shows you the signs and asks you to pick; the words on the card are not on the test. Maryland Driver's Manual, p.21: “Do Not Enter”
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.
