Drivers are being reminded to follow the Highway Code in a Transport for London (TfL) road safety campaign.
Leaflets, posters and adverts will remind people of regulations and penalties for civil traffic offences.
Rules about using bus lanes, red routes, yellow lines, box junctions and other controls will be explained.
David Brown, director of TfL surface transport, said: "If drivers follow road and parking regulations correctly, there are benefits to all road users."
He added: "We have seen real improvements on London's roads, for example, average bus speeds are going up and journey times are going down."
Following a similar TfL campaign last year, 75% of people questioned said it made them reconsider how they should drive.
