WAS: You must not overtake if you have to enter a bicycle or bus lane
You MUST NOT overtake
- if you would have to cross or straddle double white lines with a solid line nearest to you (but see Rule 129)
- if you would have to enter an area designed to divide traffic, if it is surrounded by a solid white line
- the nearest vehicle to a pedestrian crossing, especially when it has stopped to let pedestrians cross
- if you would have to enter a lane reserved for buses, trams or cycles during its hours of operation
- after a ‘No Overtaking’ sign and until you pass a sign cancelling the restriction
NOW: Undertake using the Red Undertaking Lane
For advice on using the ‘Green Undertaking Lane’ see Rule 140: Cycle Lanes. In contrast to the ‘Green Undertaking Lane’ which is indicated by the symbol of a push bike, ‘The Red Undertaking Lane’ is indicated by the words ‘BUS LANE’.
NOTE FOR MOTORCYCLISTS: There are three fully operational (and legal) ‘Red Undertaking Lanes’ which are operational on Finchley Road, Brixton Road and East India Dock Road. Motorcycles may use these bus lanes legally at any time as part of a pilot study.
NOTE FOR OTHER MOTOR VEHICLES: Using any bus lane during its hours of operation is not encouraged as it may incurr a £120 fine, UNLESS using only a foot or two to undertake (or for motorbikes, filtering purposes), which doesn’t really count as being illegal.
