I was thinking about this the other day after an article in CM about a hijacking, and came across this http://www.askthe.police.uk/content/Q587.htm on the national police website. Might be of some help.
Edit: Link fixed.
Excellent advice from the link, thank you.

I could be wrong on this but I seem to remember that if an unmarked police vehicle wants you to stop and you are not happy with that then you can follow it to the nearest police station… I await an expert on this matter… SHREK
- where are you…
Here I am…
Don’t worry Phil, the pigs can’t stop you in an unmarked car…the constable must be “in uniform” and that means the motor has to be marked too. You don’t have to stop for them.
I like the idea of carrying a card to show the nice officers though…Mine would say “[zb] Off Copper! You’ll never Take Me Alive, I’m innocent and make no mistake”
As far as killing an intruder in the cab goes…well, as long as you can justify it, then you can use as much force as is reasonable to defend yourself (Section 3, Criminal Law Act), although to be honest mate, you’d struggle to justify actually killing someone…which makes me wonder how the Govt are getting away with killing our industry, could we use reasonable force to stop 'em doing that? NO, it’s one rule for them and another for everyone else.
Your answer from plod (if you get one at all) will be political correctness gone mad wrapped up in a lovely warm jacket of management-speak. PLEASE post it up if you get a reply!
Sorry, but even ex-coppers have to stick to the rules. L.

Not so i’m afraid… The offence is failing to stop for an officer in uniform, thats it nothing relates to the vehicle. especially if it has lights and siren.
I pointed out that they sometimes get in to the cab with keys cut by RDC staff while they are loading your trailer.
is this a new phenomenom?
i’ve never heard this one in over 25 years on the road.
they’d have to be bloody quick to take a mould, copy a key and have it in the hands of the hijackers by the time you leave, or do they have key cutting machines in the book in offices of RDCs these days.
That’s absolute carp that you don’t have to stop for an unmarked car, what a load of cobblers. See you on the next episode of road wars when they tpac you for failing to stop! Holding up a sign saying I will go to nearest police station is acceptable I would say.
I must agree with shrek. after all he knows about this stuff as he has a past.
Trouble is, I have a past too, Just like many others on here.
I know what i’m capable of.
You get arrested and sent to prison here for the same thing they give you a medal for when your not here.

On this issue, I’d agree with Greg. Whilst ‘over the pond’ they have offences such as ‘unlawlful flight’ (which has nothing to do with flying 
) or ‘evading arrest’, such offences do not exist in the U.K.
Getting back to the original question, there is a vast difference between being ‘pulled over’ on a busy stretch of the M6 on a Friday afternoon and the ‘wild and woolly’ expanses of the M50 in the early hours of the morning. Each situation would have to be judged on its merits. After all, when VOSA have the ‘pull in’ signs out on the M6 above Stafford, who would choose to ignore them on the basis that they were carrying a ‘valuable load’?
The best advice would always be to, if in doubt, seek to keep moving, and quote the VRM of the vehicle over the 9’s.
This reminds me of tale. 
Driver ‘trunking’ engines between car assembly plants. Not exactly ‘trunking’ as he would be doing two or three trips a night. He spots a Transit van pulling up gradually alongside him. He has already ‘clocked’ two in the front and a third occupant behind the seats.
Passenger in the Transit starts pointing and signalling for him to stop. At which point he is ‘nodding his head’ to the passenger, whilst at the same time dialling the 9’s.
9’s Op isn’t too interested until the question of the value of the load is discussed, whereupon he enlightens them to the fact that it is probably in the region of £ quarter million.
Following the shocked silence, the next question from the 9’s Op was regarding the noise that they had just heard. “They pulled in front of me and braked, so I rammed them.” Came the reply.
Hence the stakes were “Up’d”
At a subsequent junction, ‘blue lights’ were on the carriageway, which caused the aspiring offenders to take the exit slip which, in turn, was blocked. 
Whilst I’ve never able to validate the tale, I have no reason to doubt its authenticity.

Take it you never seen police camera action then or all the other programs whereby unmarked police cars chase vehicles 
In my high value load training, we were taught to flash the card, and automatically hit the 9’s, give the vrm and any other details and ask the operator to radio the car in question with the fact your high value, or funky ADR, as this will be recorded so the officers don’t screw you for failing to stop. The operator can then also advise where the nearest station is.
This saves any confusion and stops and copper who got out of bed the wrong side that morning from nailing your ■■■■ to the wall, or putting nice holes in your bosses brand new re-treads.
Well since the police these days can flash up ‘follow me’ etc in the back window - would a scheme work whereby their car would flash up a code immediately, just a few numbers/letters, which would be generated at random and linked to their main computer, and you could then check with 999?
