The Bill seeks to reduce the default speed limit on restricted roads, generally residential streets and minor roads in urban areas, from 30mph to 20mph.
The briefing sets out the definition of a restricted road, outlines public opinion research into 20mph speed limits and summarises research into the effectiveness of sign-only 20mph limit schemes implemented across Great Britain over the last few years in:
Reducing average vehicle speeds
Improving road safety
Reducing local air pollution
Increasing levels of walking and cycling
It goes on to outline the provisions in the Bill, its financial implications and consultation undertaken by Mark Ruskell MSP prior to its introduction.
