In a construction site yesterday (Sunday, so not a single worker was present), the speed is 60 km/h. This is normally an 80 km/h stretch of 4 lane divided. I was doing 60 on my motorcycle and I got a K band alert from my Redline-O. Sure enough, there was a red Dodge Ram parked in the 60 zone with a guy in the driver’s seat and the truck all decked out with photo radar hardware. I didn’t get much advance notice, pretty much line of sight and barely enough to slow down had I been speeding but still sufficient warning I would suspect. Still, I was surprised the Redline alerted me at all; I thought all Winnipeg mobile photo radar was either laser or undetectable K band? My Redline is remote mounted on my bike so I couldn’t see the frequency.
