There's no excuse. As nearly every UK motorist knows, you have to wear a seat belt in a moving car if there's one fitted.
But take a trip on a coach or minibus and all commonsense fails, with many passengers believing they don't have to clunk click.
A new survey of the nation's motorists shows that 40 per cent of male drivers and 39 per cent of female drivers are convinced that you don't have to wear a seat belt in a minibus or coach.
But that isn't necessarily true, says breakdown service Autonational Rescue who undertook the research.
Spokesman Ronan Hart says: "For a start, the driver of any vehicle, including minibuses and coaches, must always wear a seat belt where one is fitted.
"But when it comes down to the rules for bus passengers, the law is confusing.
"For example, passengers in small minibuses, that weigh less than 2,540kgs unladen, must wear seat belts where fitted.
"But passengers of larger, heavier minibuses and coaches don't have to! Though the Department of Transport recommends they are used where fitted."
The survey of UK motorists -by Research Surveys of Great Britain - showed that 52 per cent of all motorists believe that you have to wear a seat belt on coaches and minibuses.
