British drivers regularly commit speeding and other driving offences, according to a survey carried out by online insurance company swiftcover.com.The most striking result relates to speeding, where four out of five (79 per cent) of the 500 British drivers polled admitted to have exceeded the speed limit on motorways. 71 per cent admitted to have exceeded speed limits on A/B roads; 61 per cent have done so in towns. Interestingly, the proliferation of speed cameras on roads today, together with satellite navigation systems which alert drivers to upcoming cameras, are having a detrimental effect on peoples' driving habits. Two thirds (68 per cent) of drivers said they had slammed on their brakes when approaching a speed camera and 72 per cent said they had increased their speed as soon as they had passed a speed trap. The illegal use of mobile phones whilst driving showed itself to still be high on the list of offences - 66 per cent of those surveyed admitted to using a hand-held mobile phone whilst driving their car. Forget ‘Amber Gamblers', 18 per cent of drivers admitted to have driven through a red light. 42 per cent regularly forget to indicate, whilst remarkably one fifth of drivers (19.6 per cent) said they deliberately didn't indicate. It's not just moving violations; two fifths (40 per cent) of drivers admitted to parking on a double yellow line to collect something from a shop. Road rage is also a cause of high levels of driving offences. Those drivers who continually hog the middle lane on the motorway have caused more than half (57per cent) of respondents to undertake the car in front. Sometimes it is the fact that cars are not going fast enough which causes a problem - nearly one in three (31 per cent) drivers admitted to tailgating a slower car ahead of them.Despite the relatively high levels of traffic violations, 84 per cent of the survey participants had a clean driving licence, with only 3 per cent ever having received a driving ban. More interestingly the majority of drivers did not realise that traffic violations had any impact on their car insurance. 65.4 per cent did not realise that traffic violations could invalidate your car insurance, and 82.7per cent would not think to check their car insurance policy with regard to this matter before buying car insurance.Craig Staniland, underwriting director of swiftcover.com, said: 'While there are numerous measures and campaigns to improve driving standards, many people still take liberties while driving. The fact that a high proportion of drivers don't know this affects their insurance is a major concern. At swiftcover.com our experience shows that drivers with one speeding conviction are just as safe as those with none, so we do not charge those unfortunate enough to have been caught once. However, we would encourage all drivers to check their policy before purchasing their car insurance so there are no hidden surprises.'On a more positive note, most drivers (84 per cent) said they were in favour of turning areas with a high volume of pedestrian traffic, near schools for example, into restricted 20 mile an hour zones. Hopefully the rules will be adhered to in these areas.
