For many drivers traffic in Birmingham is slow enough. However, the speed limit will be cut to 20mph on about a third of the city's roads by next March under a new pilot scheme announced today.
Imran Sajjad, from the Road Residents Association, welcomed today's announcement but is not confident it will make a difference.
Birmingham already has some 20mph zones. Similar schemes in Bristol, Portsmouth and Warrington are credited with decreasing accidents by up to 25%.
Councillor James McKay, from Birmingham City Council, says lowering the speed limit in some places should encourage more people to walk and cycle.
Main A and B roads will not be affected by today's announcement.
The council says 400 people are killed or injured on the city's roads every year. It is hoped bringing the speed down will bring that number down, too.
