Advanced stop line

An advanced stop line (ASL), also called advanced stop box or bike box, are road markings at signalised road junctions allowing certain types of vehicle a head start when the traffic signal changes from red to green. Advanced stop lines are implemented widely in the United Kingdom, Denmark, and other European countries.
