Drivers could be risking their car insurance by speeding even when they do not mean to, according to a survey by the Institute of Advanced Motorists (IAM).
Out of the 3,000 motorists polled, 90 per cent said they want to comply with speed restrictions, but 60 per cent admitted that they find it hard to stay within the limit.
Meanwhile, 40 per cent said they were encouraged to be on their best behaviour in the presence of a police car, but only ten per cent were bothered by speed cameras, even though speeding tickets can impact car insurance.
"There is a discrepancy between drivers' perception of the correct speed and the posted limits imposed by authorities ... if we can get the limits right it is clear that many more drivers will stick to them," commented Neil Greig, director of policy and research at the IAM.
Another study by the institute revealed recently that one-third of motorists experience road rage so badly that it affects their driving ability.
