Flashing Truvelo?

[billlees]

On my way to work this morning I went through the local speed trap on A18 (Carr House Rd Doncaster)

This is on a dual carriageway and forward facing. It uses road sensors and has just two lines across the road. I know the trap, and had slowed down to 35 in a 40, as I approached.

I was overtaken by another car, he went through the trap, No flash.

I changed to the outside lane as I wanted to turn right at the next turn. Just as I crossed the lines the camera flashed, even though I was only doing 35!

1. I thought truvellos of this type were infra red and did not flash, but identified the driver, hence the reason for forward facing cameras.

2. I know for certain I never exceeded 35

Anyone got any thoughts on this?

Perhaps it wasn't a truvelo and was a regular gatso facing the opposite direction?

Truvelos do flash but they are in the infra-red range. You can still see them flash but only when its quite dark.

GATSO's can apparently flash you going head on, but I think there should be some serious health and safety problems...

I have seen a Truvelo flash with a standard white light. It was on the A505 going in to Luton and is in a 40 zone, and a Merc shot past me at probably about 70mph plus.

Maybe a standard flash gets tripped above a more excessive speed to warn other drivers that yes, the thing is active?

The pair on the A1 at beeston (I think) flash pink after dark.

I saw one hitting a peugot that was only just crawling past me.

I was doing the limit but stamped on the anchors anyway!

What's the blue flash? 50'ish over the top of A14 in Nasty Northants, 50mph... 40mph... make up your minds for God's sake! Target Euro 550 no sound did it make. Anyone enlighten me? Must remember to keep Tuscan in 1st when in Northants.
