Les Cedres, Quebec Speed Traps
There are 2 places 1 is just after exit 26 toward the canal there is normally a cop sitting waiting to hit speeders and the second one is after the canal road near St-Sophie in the 50 zone.
There is an unmarked car hiding behind the overpass after the exit of les cedres and there is 2 cops further ahead to tell you to stop if you have been caught. The thing is they shift direction on the highways. So if you’re heading east or west on the 20 they might be hiding being the overpasses. With the laser radar they only need a second to get your speed.
