Moving Over For Stopped Vehicles

In Missouri, a driver approaching a stationary vehicle showing lighted red, red and blue, amber, or amber and white lights proceeds with caution and, on a road with at least four lanes and two going the same way, changes into a lane not next to it if that can be done safely. If changing lanes would be unsafe or impossible, the driver proceeds with due caution and slows to a safe speed.
