London's congestion charge will be put on hold between Christmas and New Year to help boost business.
The £5-a-day toll will be suspended on the three working days between 25 December and 3 January.
London mayor Ken Livingstone said it would benefit shoppers, businesses and residents at the start of the sales.
Residents and businesses were consulted on the move following a study of traffic congestion in the charging zones over Christmas last year.
"The suspension of the congestion charge, coupled with the post Christmas sales, will benefit visitors and businesses over the period," Mr Livingstone said.
"I promised to suspend the charge between Christmas and New Year and having listened to the views of Londoners and businesses, I can now confirm that this will happen."
