What are they?
Advanced limit lines are solid white lines extending across all approach lanes to indicate where vehicles must stop in compliance with a stop sign or signal.
How do they work?
Advanced limit lines provide extra space between stopping vehicles and pedestrians in the crosswalk, while also increasing visibility between pedestrians and motorists. By indicating drivers to stop before an intersection, advanced limit lines reduce collisions and close calls between vehicles and people crossing the street.
