HC Deb 21 March 1979 vol 964 c619W
Mr. Wiggin

asked the Secretary of State for Transport what is his most recent estimate of the number of lives that can be saved annually if 100 per cent. of all front seat passengers and drivers wore their seat belts and if 75 per cent., 50 per cent., and 25 per cent., respectively, did so.

Mr. William Rodgers

As the current seat belt wearing rate for drivers and front seat passengers of cars and light vans is estimated to be around 25 per cent.—over an average 24 hour period, the rate during daylight hours being around 30 per cent.—no additional savings are given for the 25 per cent. rate. The other latest estimates are set out below:

All hours seat belt wearing rate Potential savings
Killed Seriously injured
100 per cent 1,000 10,000
75 per cent 650 6,500
50 per cent 300 3,000
