What does a double yellow line on the road signify?

A double yellow line on the road indicates that no stopping or parking is allowed at any time. This road marking is a clear instruction to drivers that they must not halt their vehicles in that area, ensuring the roadway remains clear for traffic flow and safety. The presence of double yellow lines typically signifies important regulations about road use, especially in places where the stopping of vehicles could lead to safety hazards, congestion, or obstruction.

In contrast, double yellow lines do not imply that parking is permitted during specific times, allow for overtaking, or indicate single lane traffic. These functions are addressed by other types of road markings or signage. Therefore, understanding the meaning of a double yellow line is crucial for all drivers, as it helps maintain order and safety on the roads.
