Do Not Pass
The DO NOT PASS traffic sign tells you where passing is not permitted. Passing areas are based on how far you can see ahead. They consider unseen hazards such as hills and curves, intersections, driveways, and other places where a vehicle may enter the roadway. These signs, along with pavement markings, indicate where you can pass another vehicle, the beginning and ending of a passing zone, or where you may not pass. Where it is permitted to pass, you may do so only if it is safe. Be aware of road conditions and other vehicles. Also look for double solid lines on the highway.
