Why are there speed limits on roundabouts that are on a dual carriageway?
Point in question, A46 M6 to Coventry (though there are plenty of others), national speed limit to the island then 40 signs for 20 yards on the island then NSL on the dual again.
What’s the zb point? You’ve gotta slow for the island anyway so why post superfluous signs and limits?
How much does it cost a local council in these times of austerity to change a speed limit? I’m talking lawyers fees and advertising in the local press?
What a waste of time and (your, mine, our) money
