43. Bike box

A bike box, also called an advanced stop area, is a marked space at a signal-controlled intersection where cyclists can wait ahead of motor vehicles while the traffic light is red. It is usually positioned between two stop lines and may display a bicycle symbol.

A bike box helps increase cyclist visibility and allows cyclists to position themselves clearly before traffic starts moving. The exact users, markings and traffic-light rules vary between countries.

Where should a car wait when a marked bike box has a red light in the United Kingdom?

Under UK Highway Code Rule 178, motorists must stop at the first white line reached on red or amber. If already across it when the signal changes, stop as soon as possible and no later than the second line; do not reverse to clear the box.

Does a bike box let cyclists ignore a red signal in the United Kingdom?

No. A bike box is a positioning facility, not a general exemption from red traffic lights. Cyclists must obey their applicable lights and any specially authorised turn indications. Turning drivers must check for cyclists moving off when signals change.
