I scanned through ICBC's site not long ago, and haven't found much that would apply directly to us (yet). The one that caught my eye most was related to stopping distance, 10m (29.5') from 30 kph (18mph). I have a couple of marks painted in the lane behind the house to tune brakes now.
The three times I've passed officers (out of vehicle at the roadside) I've ridden past at low rpm, smiled and waved, and they smiled and waved back. I try not to be too crazy when there's definately police in the area.
