Strange Signage?

[Trooperone]

I saw this at Stockport Manchester. So which way do you go here no cars can go right or left?

[Ruperts Trooper]

Surely that signage means that cars/HGVs must turn left while buses, taxis and cycles can turn left or right.

Those are both conveying the same message, are they not?

Yes, "must turn left" and "must not turn right" mean very much the same thing if the only options are left or right, which appears to be the case here. The exceptions agree, so I don't see any scope for confusion.

It is classic Stockport to mix signs like that though, the correct sign to use here would have been a blue turn left arrow to match the road marking.
