What do slanted stripes on the road indicate?

Slanted stripes on the road indicate areas where vehicles should not change lanes, serving as a visual guide to restrict lane changes in potentially hazardous situations. These markings are typically used to indicate that lane changes are discouraged or prohibited, such as in areas near intersections, on highway entrances and exits, or in places where visibility is limited. This helps maintain safety on the road by preventing conflicts between vehicles and enabling smoother traffic flow.

While the other options mention various traffic indicators, they do not accurately describe the primary function of slanted stripes. Safe lane change areas would have different markings, pedestrian crossings are usually marked with symbols or lines that are distinctly different from slanted stripes, and speed limit zones are indicated through posted signs rather than road markings. Understanding the significance of road markings enhances a driver's ability to navigate safely and responsibly.
