Maryland Traffic Law and Rules of the Road
Learn the scene, not just the citation
Maryland rules questions come from Title 21 of the Transportation Article, but they are written as scenes. A candidate must be fluent in right-of-way at uncontrolled intersections, four-way stops, and left turns; in yielding when entering a roadway from a driveway, alley, or parking lot (you yield to everyone already on it); in signal timing (at least 100 feet before a turn or lane change); in reading pavement markings, including the two-way left-turn lane; and in when passing on the right is lawful (generally when the vehicle ahead is turning left, or on a roadway wide enough for two lanes each way).
Speed: posted limits always control. The statutory defaults most often tested are 30 mph in business and residential districts and 15 mph in alleys. Know Maryland's Move Over law - change lanes or slow down for stopped emergency, tow, and roadside vehicles with lights flashing - and the requirement to leave at least 3 feet when passing a bicycle.
Traps: right turn on red requires a full stop and is void where posted; a school bus with flashing reds requires a stop on undivided roads, but opposing traffic on a divided highway with a physical median does not stop; "yield" means be ready to stop, not ease off; the left-turning driver yields to oncoming traffic going straight or right.
Worked example - four-way stop: two drivers arrive at the same moment. The one going straight proceeds first; the one turning left waits, because a left turn crosses the other's path. If arrival order differs, the first to stop goes first, and a tie always resolves to the vehicle on the right. Arrival order grants right-of-way; it never cancels the duty to avoid a crash.
