What do double solid lines in the center of the road indicate?

Double solid lines in the center of the road convey a clear message regarding vehicle movement: they indicate that no passing is allowed. This design is used to enhance safety by preventing drivers from overtaking other vehicles in areas where visibility is limited or where conditions may not properly allow for the safe execution of a passing maneuver. The presence of these lines signals to drivers that they should remain in their lane and not attempt to cross the lines to pass another vehicle.

The regulation is particularly important in locations where hazards are present, such as curves, intersections, or near pedestrian areas, ensuring that all drivers maintain safe distances and can react appropriately to any unexpected circumstances. Adhering to this rule contributes significantly to road safety and reduces the likelihood of accidents resulting from unsafe passing attempts.
