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?

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.
