What does a solid yellow line indicate?

A solid yellow line on the roadway indicates that the area is a no passing zone. This marking is specifically used to signal drivers that overtaking another vehicle is prohibited in this section of the road. The purpose of this rule is to enhance safety by preventing passing in locations where visibility may be limited or where it's dangerous to do so, such as on curves, hills, or near intersections.

In contrast, passing is not allowed over solid yellow lines due to the increased risk of collisions and accidents. It is important for drivers to heed these markings to ensure the safety of everyone on the road and to comply with traffic regulations. Other markings, like a broken yellow line, would allow for passing when safe, but the solid line clearly restricts this action. Knowing these rules helps promote safer driving practices and reduces the likelihood of accidents.
