英语翻译
Motorways are,no doubt,the safest roads in Britain.Mile for mile,vehicle for vehicle,you are much less likely to be killed or seriously injured than on an ordinary road.On the other hand,if you do have a serious accident on a motorway,fatalities are much more likely to occur than in a comparable accident elsewhere on the roads.
Motorways have no sharp bends,no roundabouts or traffic lights and thus speeds are much greater than on other roads.Though the 70 m.p.h.limit is still in force,it is often treated with the contempt that most drivers have for the 30 m.p.h.limit applying in built up areas in Britain.Added to this is the fact that motorway drivers seem to like traveling in groups with perhaps barely ten metres between each vehicle.The resulting horrific pile-ups when one vehicle stops for some reason--mechanical failure,driver error and so on--have become all too familiar through pictures in newspapers or on television.How many of these drivers realize that it takes a car about one hundred metres to brake to a stop from 70 m.p.h.Drivers also seem to think that motorway driving gives them complete protection from the changing weather.However wet the road,whatever the visibility in mist or fog,they plough at ridiculous speeds oblivious of police warnings or speed restrictions until their journey comes to a conclusion.
