State Route 342 near Autoroute 20 Westbound
The speed limit is 50 km/h as it is an urban boulevard, and then it changes to 100 km/h maximum and 60 km/h minimum (not a typo) about 300 m after the intersection with Route 342. They can be anywhere from Avenue Ranger (where the McDonalds is) until the 100 km/h sign, on one occasion they were right besides that sign and were ticketing starting at 60 km/h! Enforcement is semi-frequent and can happen literally anytime. There used to be a speed trap going East in that area, but it appears to no longer be in operation, they gave so many tickets over the last 10-15 years that no-one except the odd non-local driver goes over the limit there.
