A draft document published yesterday by the Welsh assembly contains stern proposals to cut road accidents, including encouraging firms to ban workers from drinking alcohol and to fit speed limiters to company cars.

Other ideas being considered by the assembly's environment and transport minister, Sue Essex, are a hotline to shop dangerous drivers, and more cameras and speed limits. The government has set targets for 2010 of a 40% cut in adult road deaths and serious injuries, and a 50% cut for children. In Wales 169 people were killed on the roads last year, compared with 322 in 1976. The document states: "We know we can reduce road casualties further."

Prohibition of drink during the work day is policy for some firms; the assembly could not oblige others to follow suit, but could put pressure on them to do so voluntarily.

"Home zones" could give pedestrians priority and make vehicles travel at little more than walking pace. The idea is being piloted in a village in Monmouthshire. An assembly spokesman said: "These are possible solutions for consultation. Some will be goers, others won't."
