Yellow lines are used as left-edge lines on one-way roadways and divided roadways. (On a divided roadway, the "left edge" is between the leftmost lane and the divider.)
Do not block an intersection, even if an emergency vehicle is approaching. If you are in an intersection when you hear or see an emergency vehicle approaching, continue through the intersection. Then pull over to the right as soon as you can and stop.
Vehicles such as buses and post office vans make frequent stops. And every stop represents a hazard. When following one of these vehicles, you should maintain a greater following distance than usual.
Always park in a designated area if possible. If you must park on a roadway, park your vehicle as far away from traffic as possible. If there is a curb, park as close to it as you can.
