Signal indications — Maryland Permit Test
Signal indications on the Maryland permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A steady red light means stop before the stop line, crosswalk, or intersection and remain stopped, except for a turn on red that is permitted after a complete stop.
Stopping before the line keeps the crosswalk clear and lets cross traffic see you; you stay there until the light changes or you make a turn red allows.
A steady yellow light warns that the signal is about to turn red; stop if you can do so safely.
Yellow is time to clear the intersection or stop, not time to accelerate — most intersection crashes start with someone deciding to beat it.
A steady green light means you may proceed after yielding to vehicles and pedestrians already in the intersection.
Pedestrians and vehicles caught in the intersection when the light changed have nowhere to go, so they clear first.
A green arrow means you may proceed with caution in the direction of the arrow, after yielding to any pedestrians and vehicles already in the intersection.
The arrow tells you which movement is now allowed; it does not empty the intersection of whoever is already inside it.
A steady red arrow means traffic turning in the direction of the arrow must stop.
A red arrow stops one movement while others continue, so it must be obeyed like any red.
On the test
A steady yellow traffic light means...
the light is about to turn red — stop if you safely can. Yellow is time to clear the intersection or stop, not time to accelerate — most intersection crashes start with someone deciding to beat it.
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.
