What Does a Construction Speed Zone Cost?
What construction zone? I didn't see any construction speed signs back there! This irate motorist was very definite expressing what she thought about the traffic ticket I was issuing her for speeding in a construction zone. I suggested that once we were done I would be happy to help her make a U-turn so that she could go back and check on the signs.

Question: I was stopped by a motorcycle officer over a 60 kph bridge. I was going over the posted limit and unaware of the excessive speed consequences. The officer said that he was pacing me and I was "pulling away from" him. I was asked initially how fast I thought I was going and ignorantly and mistakenly guessed 110.
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.
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?
