There is no doubt that excessive speed kills. The question as to applying local speed limits on a time basis complicates the issue further. Flashing amber lights in school approaches during school hours is one practise adopted by some authorities with a reduction to 20 mph. Outside these hours the speed limit is as for the rest of the road. Really, as one senior policeman has just discovered, we are all tempted to speed when the road is clear - however that can lead to points on the licence - or worse, an accident caused in part or in full by our own actions. I suggest we keep speed for the track and obey the law - though there is no reason why everyone shouldn't campaign to have the limits changed where they seem redundant or incorrect. Clear markings would also help as having to count the distance between lamposts only detracts from driving.
