Traffic Officer 4x4s

[cymtriks]

I've recently seen a lot of these going up and down the M5 between Bristol and Gloucester. Most drivers treat them as police cars and overtake them at circa 72 while the TOs are doing 69. They have orange chevrons on the back.

What are they? Police? SCPs? road works crews?

I've seen two or three every day for a few weeks now.

Curious.

Edited to add-
I saw one of these with twinkling lights on J14 bridge yesterday. Possible mobile SCP site?
