They did the same here. 30mph zone, going into NSL single carriageway on a STRAIGHT section of road, back into a 30mph zone. Thing is the STRAIGHT section of road had a crap road surface and was very bouncy and was awful to drive and 2accidents occured over about 5 years.

What did they do? RESURFACED the road so it was all smooth and was a pleasure to drive on...then dropped it to a 40mph limit. And since that limit has been imposed there has STILL been 2 more accidents WITHIN 18 MONTHS, one of which a Citroen Xsara came off the road and crashed into a toilet block. Can't tell me that the speed limit reduction has helped eh?

Edit: And just to add, straight section of road where you can see EVERYTHING ahead, yes people just belt past those doing 40mph at WAY above 60!
