Insurance incentives and seat belt use.

In 1983, Nationwide Insurance Company increased compensation payments for its clients injured or killed in a motor vehicle crash while using a seat belt. A survey of belt use was undertaken in the month after all those so insured had been informed of the change. Belt use by drivers insured by Nationwide was not significantly different from that of drivers insured by other companies. The incentive appears to have had no apparent effect on belt use.
