The survey was conducted by observing the behaviour of several motorists at sites in the Dublin area, as part of the firm's 'Pass it on!' courtesy campaign.
The survey reveals that men aged between 40 and 50 were the most likely to give other drivers a helping hand, whereas women below 30 tended to be the most courteous to other drivers.
Drivers of luxury cars were less likely to let someone in than the general motoring population according to the survey. On a positive note, 77 percent of drivers signal their appreciation when a fellow motorist has done them a good turn.
