When approaching an intersection with a steady green traffic light, yield to pedestrians in the crosswalk and vehicles still in the intersection.

You may not pass another vehicle on a hill or in a curve because you cannot see oncoming traffic and may cause a collision. Never pass another vehicle by driving onto the shoulder of a highway. Passing another vehicle by driving over a solid yellow line is prohibited.
