Does anybody know what this strange thing is for? I’ve seen a few around the motorways but I can’t find out what they do. Two grey pincers in front of a black body (but no poisoned stinger).
This is M25 jct4 anti-clockwise exit slip road

Can anyone help cure my bafflement?
I`ve seen some thing simlar on road side weather stations, to measure visability? for fog warning, speed signs on matrix boards would be my guess.

So why does the ‘FOG’ warning still come on during bright blue days?
