Where are no passing zone signs typically found?

No passing zone signs are typically located on the left side of the road. This placement is strategic because it ensures that drivers can easily spot the sign as they approach an area where passing is not allowed, particularly on two-lane roads where visibility may be limited. The sign serves to alert drivers to the specific stretch of roadway where passing is prohibited due to factors like curves, hills, or other potentially hazardous conditions. This positioning helps reinforce safe driving behavior and keeps both drivers and pedestrians safer.

While no passing zones could theoretically be more significant near intersections or pedestrian crossings, the primary intention of these signs is to address sections of road where the passing of vehicles poses a unique risk, making their placement on the left side appropriate.
