M3

The M3 motorway in the UK was opened in 1971 and runs from Sunbury-on-Thames in Surrey to Southampton in Hampshire. It is an important route linking London to the west coast of the United Kingdom and is part of the larger E3 European route. It is 109 miles (175 km) long and consists of two lanes in either direction for most of its length, with the western section of the route dual carriageway.

Safety on the M3 has improved in recent years, with the number of fatalities falling from 26 in 2011 to only 7 in 2019. This is in part due to the introduction of various measures such as improved signage, reduced speed limits and real-time traffic warnings. Additionally, regular patrols are carried out to ensure that drivers are adhering to the rules.
