Licensed taxis and private hire cars will be allowed to stop on red routes, the Mayor of London has announced.
From 10pm to 6am any passenger needing to withdraw money to pay for their journey can ask their driver to stop near a cash machine on red routes for up to five minutes.
The scheme, requiring drivers to display a sign showing their participation, will be piloted for six months.
Transport for London will then consult drivers, passengers and local authorities to consider the overall effect of the policy.
Boris Johnson has also asked TfL to consider improving card payment arrangements for taxis.
He said: "As Mayor I want to make life easier for Londoners, and this is just one of the ways that I will be doing so."
If the pilot is successful, TfL will decide whether exemptions from stopping restrictions can be extended.
