Evidence demonstrating the advantages of seat belts in improving safet
y of road travel is overwhelming and has resulted in government legisl
ation. This study was performed to investigate compliance with this le
gislation by fast-moving traffic on British motorways, for which no pr
evious data exists. Analysis of seat belt use by 2564 travellers in 15
26 cars in October 1992 revealed the following rates of use: drivers 9
8%; front passengers 96%; rear seat passengers with available belts 53
%. The overall low rate of rear seat restraint use was seen in all age
groups except babies. When the study was repeated 8 months later, the
rates of restraint amongst 3910 travellers in 1881 cars had not incre
ased. In view of the continuing heavy death toll on British motorways
and roads, there is an obvious need for measures to improve rear selt
belt use. This would be most appropriately achieved by both enforcing
and publicizing the current legislation.
