Insurers see risk in some odd occupations.My wife's jewellery insurance had a clause excluding people in the film, theatre and entertainment business,, and jockeys! Quite what jewellery the likes of Kieron Fallon would be wearing was not obvious, nor why they were at greater risk of losing it.
But similar assessments of risk apply to driving. Motor traders and entertainers do more miles for one thing, entertainers often at night between gigs, and one broker said that the risk of passengers claiming a lot in damages in an accident caused by the insured could sometimes be a consideration; the old joke that the most expensive accident is colliding with a bus load of bookies on their way to Ascot, comes to mind; some occupations carry more expensive passengers than others (loss of earnings etc) Entertainers may fall into that category.
