The amount of crashes involving lane changes on the motorway is on the rise, with the total going up by almost half in the last two years.

The potentially high-speed accidents account for more than six percent of UK crashes, and create vehicle damage that costs as much as £437m a year.

Research by Accident Exchange has revealed that there are more than 152,000 blind-spot crashes each year, with each one costing on average £2,876 to repair.

The most common cause, according to the accident management company, was drivers changing lanes without checking their blind spot and without indicating. In the majority of cases the driver was moving from right to left – from the fast to the slow lane on a motorway for example.

The rise in accidents comes despite more vehicles now offering technology that will alert the driver to the presence of another car in the area that is not covered by the rear-view and door mirrors.

Experts have attributed the rise partly to an increase in safety requirements from the EU, which have increased the size of modern cars' pillars, in turn reducing in-car visibility.

"Today's cars are packed with 'active' safety equipment, but for some vehicles strengthened frames can mean reduced visibility and larger blind-spots," said Lee Woodley of Accident Exchange.

"Older cars tend to have slimmer pillars which don't obscure the driver's view to the side or rear as much."

However, we would take the increased safety of modern cars, over the tin-box construction of our dad's first car any day.
