Right-of-way is given, not taken

In Missouri, as in every state, "right-of-way" describes who is legally required to YIELD — not who is allowed to go. The MO DOR handbook is explicit: even when the law gives you the right-of-way, you can still be cited for failure to avoid a crash if the other driver is plainly not yielding. The defensive interpretation, which is what the Missouri permit test rewards, is to give up the right-of-way whenever doing so prevents a collision.

Four-way stops and uncontrolled intersections

At a four-way stop in Missouri, the first vehicle to come to a complete stop proceeds first. If two vehicles stop simultaneously, the driver on the LEFT yields to the driver on the RIGHT. At an intersection with no signs or signals, the same rule applies — but you must also yield to any vehicle already inside the intersection. Eye contact and a small wave are not legal substitutes for these rules; the test asks the rule, not the etiquette.

Pedestrians, cyclists, and crosswalks

Missouri requires drivers to yield to pedestrians in any marked or unmarked crosswalk at an intersection. A pedestrian outside a crosswalk must yield to vehicles, but the driver still has a duty to avoid hitting them. Cyclists in Missouri have the same rights and duties as drivers when riding in the road, which means you yield to them the way you would yield to another car in the same position.

Roundabouts and merging

Modern Missouri roundabouts are entered by yielding to traffic already in the circle, then merging when there is a safe gap. You travel counter-clockwise around the central island and signal right before exiting. On freeway on-ramps, the merging vehicle yields to traffic already in the through lane — adjust speed to find the gap rather than expecting traffic to brake for you.

Emergency vehicles and funeral processions

When an authorized emergency vehicle approaches with lights and siren, Missouri law requires you to pull to the right edge of the road and stop until it has passed — including from the opposite direction on an undivided road. Funeral processions in Missouri are treated as a single legal unit; once the lead car has lawfully entered an intersection, the rest of the procession may follow even on red, and you must yield to the procession unless directed otherwise by an officer.
