This case is an appeal of a traffic court conviction where the officer who issued the ticket used a visual observation of vehicle speed to base the ticket on. The estimation was 90 km/h in the posted 60 km/h zone on the Lougheed Highway near the North Road intersection.

May 2025 is a busy month for road safety campaigns in British Columbia. ICBC is holding a speeding campaign and the BC Association of Chiefs of Police are running motorcycle safety and high risk driving campaigns.
The left lane is so popular lately that when I keep right I often find myself behind fewer vehicles at the next red traffic light. In fact, at one particular intersection on my commute many times I can be first in line. Everyone else seems stuck in the left lane trying to get ahead, fuming, following too closely and making sudden lane changes.
Question: For a few months now I have been trying to locate specific information on the rules of the road pertaining to back alleys. Simply trying to get a concrete source on the speed limit of back lanes, especially those running along school zones, has been incredibly difficult.
Can you please tell me what would be a safe speed to set speed limiters on our delivery drivers vans owned by the company? Is there a need to set speed limiters higher in order for the driver to be able to pass?
When approaching a speed limit change along the highway as indicated by appropriate signage, where is the actual speed zone boundary? Am I expected to change my speed once the sign becomes visible to me so that I have reached the new limit by the time I reach the sign, or do I maintain my speed and then increase or reduce it only after I have reached the sign?
