Wrong 50 small speed limit sign in 40 zone

[Lgfst]

Good morning, a few weeks ago I was travelling along a stretch of road which dropped to 40 with large 40 signs.

A short distance later there was a small 50 repeater sign on a lamp post in the central reservation.

Went through the tunnel and then there were large 50 signs the other side.

The limit was supposed to be 40 all the way through the tunnel but where would you stand legally (say there was a camera in the tunnel) for doing 50? I didn't notice other 40mph repeater signs either.

I saved the footage on the dash cam, just because it intrigued me a little. And I wasnt speeding anyway.

The road sign reader on the car also picked up the 50 sign

Here's the footage. The small sign can be seen about 16/17 seconds in on the central lamp post

Yup. A 50 repeater that was probably forgotten. In that case, you couldn't be nicked for 46 (or whatever) until the next 40 sign.

Thanks, I thought as much but wasn't sure.
