The unanticipated cost of the London congestion charge.

When the London congestion charge was introduced in 2003, operational ambulance personnel were among a group of ‘‘key workers’’ who were refused an exemption. With the charge at £8 per day and public transport options that do not meet the needs of shift workers, many staff have sought alternatives such as motorcycling, which carries an increased risk of involvement in a road traffic collision (RTC) and a greater risk of injury when this happens. https://emj.bmj.com/content/23/12/e68 This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial. http://creativecommons.org/licenses/by-nc/4.0/ http://dx.doi.org/10.1136/emj.2006.04157
