Wayne,
I would still get pics of where he was sitting, and try to get it at the same time of day, and in the same light conditions.

You were following other cars and being passed by the truck - sounds like at least a two lane road? How closely were you following the other cars - would you have ended up in their back seat if they were going the speed limit and you were speeding? And were you in the 'slow' lane behind the other cars?

What colour was the other truck, and what colour is your Explorer? Could the officer confuse the two, especially at the time of day you were pulled over? I would take a picture of your car from the front, and a dualie that is the same colour as the one that passed you, and shrink each to about 2cm square. This is what he might see in his mirror - and at the same time he is looking up to see what the speed display on the radar says.

I would also prepare a simple set of pictures - show the road with all lanes, show where you were, and where the cars in front of you were, and where the truck was, as well as where the cruiser was. The second pic should show the truck accelerating past you and pulling in front of you, and the last pic should show the cop pulling in behind you probably thinking you were the dualie, and the other cars in front of you.

What Trularin said about line-of-sight is very 'tru' - his line of sight is limited - possibly to just his mirror, and radar may be somewhat compromised also. It sounds like his car was pointed in the same direction you were traveling. Ask him where he parked his car, and how he was angled. Ask if he was hidden behind anything.

Ask him what he was doing while he waited for speeders to set off the alarm. If he says he was looking in the mirror the whole time, follow up with a question about him being sure he didn't answer radio calls, drink coffee, shift in his seat, or anything that may cause him to take his eyes away from the mirror for even a split-second.

70kph is around 65 feet per second - that is a fair bit of travel, but 115kph is around 105fps or so. Easy enough for a guy going that fast to pass you and pull in front of you in a couple of seconds.

You said you were cited for the speed limit in the construction zone - this is good. If you are asked if you were speeding you can truthfully say that you were slowing down to comply with the change in speed limit because of the construction, and this also helps back up anything about construction equipment being present.

Not sure what the rules are in Canada, but in the US I would send a registered letter to the officer requesting the serial number, model, and calibration info of the radar gun. It helps you if he does not provide it, and it may show him you are serious about pursuing this enough for him to drop it. Course, it could also piss him off.

Hope that helps. I fought a red light ticket recently (won it), but it still cost me $75 in hearing costs (in MA you do not get those costs back even if you win).
