Drivers could be at risk of invalidating motor insurance by not declaring their car is fitted with a common feature that hundreds of thousands of vehicles have. Auto Express said it had been contacted by a motorist who was left with a six-figure bill when his insurer refused to pay out on a claim and cancelled his policy because he had not listed his car's tow bar as a 'modification' when running a quote via comparison website Money Super Market. Auto Express is warning drivers that their motor insurance could be invalid if they have failed to declare their car has a tow bar fitted. It found that comparison websites fail to list a tow bar as a modification that could impact their policy 'We were contacted by a desperate driver after his insurer, Allianz-owned Flow, cancelled his policy following an accident on the grounds that he had failed to list his car's tow bar as a modification when purchasing cover,' explains Chris Rosamond, current affairs editor at Auto Express told us. It's unclear how many cars in the UK have a tow bar fitted, though it is likely in the hundreds of thousands Rosamond says some comparison websites do not provide easy or obvious routes to information about whether a tow bar is a relevant modification to a car's original specification.
