As for police advice, it's very specific (as part of a long list of
things they don't expect you to do):

"We do NOT expect you to put yourself in danger by crossing red
traffic lights to make way for us."

http://www.met.police.uk/mpds/advice.htm

That sounds like a clever way of saying "we would like you get out of our
way at traffic lights if it is safe but if you have an accident we will not
accept any responsibility and probably charge you"

Except when you look at the page as a whole, when it's clear that's not
the hidden meaning.
