Where should the solid yellow line be located for a driver?

The solid yellow line should be located on the driver's left. This marking is used to indicate lanes of traffic that flow in opposite directions. When a driver sees a solid yellow line on their left side, it signifies that they are traveling in a lane where passing is prohibited. This is particularly important for maintaining safety on the road. The presence of the solid yellow line serves as a visual cue to drivers that they should remain in their lane and not overtake other vehicles, as doing so could lead to a head-on collision. Understanding the correct placement and significance of lane markings is crucial for safe driving practices.
