Emergency Vehicle/Red Light Question

[Robbie8666]

I've read a lot over the years about people moving into bus lanes to let emergency vehicles pass, then they've received a ticket in the post with a fine.
Bit harsh I reckon, as it is an emergency situation and is not done for your own gain.

I have been told that even blue light drivers if they go through a red light with a camera fitted have to prove they were on a 999 call via logs etc otherwise the driver can get fined!
(normally sorted out at a higher level than the driver themselves!)
