I can tell you now the 200 yard taper and 200 yard safety feels very short when you’re working on these roads, fast travelling traffic getting over well before the final 200 yard plates is safer for those working,heavier traffic naturally slows and nobody wants an idiot crossing several lanes at the the the last minute .
It’s better to be behind a car for 800 yards than kill a roadworker.
Ps had a very scary time once when an ambulance with blues came through and an idiot swooped out of its way in front of our crash cushion while I was installing,Nearly hit me .It’s nice to allow emergency services through but remember that big lorry is protecting workers in the road
