Congestion charging is being introduced into central London on 17 February in an attempt to cut traffic levels and help ease severely clogged roads. The scheme will also raise money to re-invest in the capital's transport system
The area in which charges apply is a zone measuring eight square miles (21 square kilometres) within the Inner Ring Road - the most central and heavily congested part of London.
Charges will apply between 7am and 6.30pm from Monday to Friday, excluding public holidays.
Motorists driving into the charging zone have to pay a flat fee of £5, either in advance or on the day of travel. Those who do not pay are liable for fines of up to £120.
