What do yellow lane markings indicate?

Yellow lane markings serve a crucial function in traffic management and safety. They indicate that traffic is traveling in opposite directions, which is essential for maintaining safe separation between vehicles moving towards each other. This distinctive coloration helps drivers understand the flow of traffic and stay in their respective lanes, ultimately reducing the potential for head-on collisions.

In areas where yellow lines are present, such as in the middle of a two-way street, they provide visual cues that designate which lane is intended for which direction. This can be particularly important at intersections or on roads shared by various types of vehicles.

While the other options relate to important aspects of road use—like traffic moving in the same direction represented by white lane markings, parking regulations denoted by clear signs or painted curb markings, and road work zones typically marked with cones or barriers—yellow lane markings specifically highlight the necessity for caution when navigating oncoming traffic. Understanding this can significantly enhance driving safety and compliance with road rules.
