A unique weather study by Norwich Union has found thatBritain’s reputation for rainy weather is unfounded.
Research by the UK’s largest insurer grouped motor claims andaccident information according to weather conditions for 2004 and2005. Contrary to popular belief, the research showed that, onaverage, it only rains 6.2% of the time across the UK at anyone time – although it is cloudy an additional 66% of thetime, which is probably not much of a surprise to anyone.
Weekends are the best time to get out for a drive, as there arefewer cars on the road – resulting in an increase in trafficspeed by 11%. Although the higher speed also means that collisionsare slightly more serious with repair costs on average about 10%more than for crashes on weekdays.
Julian Beardsworth, director of underwriting (personal lines),Norwich Union, said of the research: “Our research is theclearest indication yet of the extent to which bad and extremeweather impacts our driving performance. With the Met Officepredicting the coldest winter in a decade, motorists shouldremember that a little preparation before setting out on a journeycan avoid a breakdown or accident.”
The recent short-lived cold snap over the holidays is untypical ofrecent British winter weather: it is below freezing only 2-3% ofthe time – just 11 days a year. However, accidents increasemore than 50% when there has been a severe frost.
Julian says: “Frost and ice affect the vehicle’sability to grip the road properly. We also see a lot of accidentswhere drivers admit they had visibility problems. If there has beena frost, drivers need to allow enough time to defrost and scrapeall windows on their vehicle so that they can see properly. A cleanwindscreen – inside and out – is essential to clearvision. We’ve even heard of accidents where the driver hasliterally had his or her head out the window because theycouldn’t see through their own windscreenproperly!”
Although it’s not surprising that wet days result in moreaccidents than dry days, by just how much was a surprise. Accidentson the wettest days increase by 40% - a clear indication that evenin the rain, motorists are not taking proper precautions. The roadsare more congested in the rain as well, as people are 10% morelikely to drive when it’s raining.
Julian said: “Our research shows that drivers only slow downby 3–4% when it’s raining. We would urge drivers toslow down and allow extra stopping space between their vehicle andthe car in front of them, as stopping distances increase in wetweather. It is commonly acknowledged by road safety organisationsthat in dry conditions, drivers should allow two seconds’time between their vehicle and the vehicle ahead of them whentravelling at speed. This distance should be increased in wetconditions, and drivers should slow down accordingly.
“Accidents in wet conditions cost an average of 27% more thanaccidents on dry days – this is down to the greater impactspeed resulting from slick road conditions. That cost is not justdamage to the car, but also personal injury – so drivers needto beware that especially in the wet, speed kills.”
Finally, the report finds that extreme weather conditions of anytype tend to increase the number of accidents on the roads, soaringtemperatures add 40% while days with local thunderstorms or extremewindspeeds have 10% more crashes than wet days.
