LONDON -- The number of elderly people who will die in car accidents is set to rise dramatically over the next 30 years, researchers are warning, IRNA quoted.

Doctors in the U.S. have predicted that one in four fatal road crashes will involve drivers over the age of 65 by 2030, reports the BBC News On-line.

The projections are based on the fact that the general population is ageing and more people are continuing to drive when they get older.

The doctors have called for changes to car designs and clearer road signs in an attempt to reduce the predicted rise in deaths.
