This is the conundrum of smart motorways: they’re an excellent idea, and the stepchange in available road space really does help manage congestion. I’m all in favour of them – but people need to be taught how to use them, and this is where the Department for Transport has failed.
Because now, it’s almost an assumption that if a motorway is smart, the hard shoulder can be used all the time. And, sooner or later, I fear this is going to cause a big accident. If, indeed, it hasn’t already.
The simple solution is obvious: if the lane is closed, permanently display a big red ‘X’ in that lane. This would make it blindingly obvious to all road users. Oh, and maybe set the speed cameras to capture motorists who drive past a red ‘X’ (or at least tell people that’s what you’re planning to do).
Motorists are still getting used to smart motorways, and an apparent lack of information means many just don’t understand it. So, DfT, until you get your education campaign fully into gear, turn on the crosses. It may just save lives.
