A best practices in the United Kingdom to prevent road traffic injuries is speed cameras according to Paul Pilkington in the Journal of Epidemiology and Public Heath Medicine. In the United Kingdom there have been speed cameras set up on major roads in hopes of preventing and reducing road traffic injuries. This started in 2006 and seems to be saving lives. They decide to do this because of the high amount of traffic accidents and fatalities due to speed related accidents.
This is a best practice because the speed cameras are seen as a detergent for fast drivers. This also applies to people who do not come to complete stop at stop signs and traffic lights. This device allows the police to catch violators and ticket them for breaking the law. This device can be seen as a nuisance to drivers as well as a high cost for the United Kingdom. The key drivers and influences would be the police force as well as injury prevention team in regards to traffic accidents.
