Heads up lads…there is now active average speed cameras from the 2 donuts on the broadway walsall ringroad up to jcn 7 of the m6…30mph…stay alert.
Also white merc unit 67 plate with recording equipment catching other offences. 
But if your a professional driver and therefore don’t speed you’ve nothing to worry about even if they put average speed cameras on every single road in the UK. Oh hang on a minute silly me I’m forgetting a lot of professional drivers do ignore speed limits so this will actually be relevant to them. My bad.
