I offer my sympathies to any one who has suffered an injury or loss through a road incident. It's never a desirable thing to happen, and we should all be doing more to prevent such incidents.
I am always anoyed when we see the media interest in road incidents when a caravan is involved, it blows the number of caravan related incidents out of all proportion, especially when the number of incidents involving caravans is a fraction of a percent of all road incidents. It gives the perception that caravanner's are a major problem.
In 99.9% of all road incidents speed is the biggest factor. All drivers should drive in accordance with the prevailing conditions and not exceed the speed limits for the road, but so many drivers habitually speed, and some take such false pride in choosing to break the limits at almost every opportunity.
I frequently use a stretch of the A5 where in a two mile stretch of dual carriage way there are 5 speed cameras set to 40, and 6 sets of traffic lights. It amazes me the number of drivers who hammer on at 50 or more, and then have to brake hard when they approach a camera, or a red light then accelerate hard until next feature. The brake dust and fuel usage must be costing them so much more, not to mention the emisions affecting the air quality.
Plan your journeys properly and allow time to keep your speed in check.
