Rules of the Road & Right of Way
Right-of-way rules keep traffic moving safely by settling who goes first. In Missouri you yield rather than force your way, and you protect stopped emergency vehicles.
Intersections and stops
At a four-way stop, the first to arrive goes first; if two arrive together, the driver on the left yields to the driver on the right. When turning left, yield to oncoming traffic and pedestrians.
Roundabouts
Enter a roundabout to the right, travel counterclockwise, and yield to pedestrians and to vehicles already circulating. Signal before you exit.
Move Over Law
When you approach a stopped emergency, law-enforcement, or MoDOT vehicle with flashing lights, move over one lane if you can do so safely. If not, slow down and pass with caution.
