Q&A - Stopping in the middle of a lane change
I notice a habit of Vancouver drivers is that when they are turning right, and the right hand lane is used for parking and/or cycling, they will casually pull halfway into the right-hand lane and then stop (either for a red light, or to yield to a crosswalk).
Even the 3rd or 4th car in a lineup waiting to turn right will do this: stopping on the dashed line.

The case of R v Kafka involves a crash between a pickup truck and truck tractor that was making a wide left turn. The pickup driver passed the heavy truck over a double solid line thinking that the truck was moving right to park at the side of the road.
Question: I often have to use a complex intersection to get to where I am going in Nanaimo. It's at the junctions of the Old Island Highway, Jingle Pot and Shenton Roads. I use the right hand turn lane on Shenton to join the traffic on Jingle Pot and move over a lane to be able to turn left at the traffic lights onto the Old Island Highway.
Nicola Varga was late for an Epicure party and was using her iPhone's GPS app to navigate westbound on the Lougheed Highway from the Golden Ears Bridge in Pitt Meadows. She needed to make a left turn at the Park Road intersection so she began to make her way from the acceleration lane across three lanes of traffic to the left turn lane for the intersection. As she crossed from the center through lane to the left through lane she was hit from behind by a delivery truck driven by Bryan Kondola.
Currently in BC, motorcycles are required to sit in traffic like any other automobile is expected to, but this is very dangerous for motorcyclists! The solution is 'lane filtering', a practice vilified by the general driving public in much of North America.
