<pedant> Not forgetting the other pedantic point - what speed is the National Speed Limit on any road? The answer is, it depends. Motorways - HGVs and buses are limited (and of course it is only a two lane road for them) to 60 but in fact recent lorries have a de facto speed limit of 56mph due to speed limiter legislation. Dual carriageways: 70mph for cars, 60 for vans (yes, even Mercedes Sprinters but not Fiesta and similar vans which are both derived from cars and also have a maximum laden weight of less than 2 tonnes who are allowed to do the same as cars), 50 for HGVs. Single carriageways: 60 mph for cars, 50 for vans (ditto Sprinters!), 40mph for HGVs. It is also worth considering that if at some point in the future there is a change in legislation, marking the limits explicitly becomes a big problem because they cannot be distinguished from actual limits. For the wrinklies amongst us, remember the 70s where the national speed limit was reduced to 50mph on single carriageway, and 60 on dual carriageways, was it 60 or 70 on motorways (not that there were that many then). They then raised them in two stages, leaving motorists of a certain age always slightly confused as to the speed limit on a dual carriageway. Spenny |
