Passing a Long Vehicle Turning Right
The driver of this car may not have noticed the flashing right turn signal on the bus, but learned the hard way that it was worth paying attention to. Passing a long vehicle turning right is obviously a dangerous thing to do and should be avoided.

Dixon Ormiston fell from his bicycle and sustained serious injury after being forced against a concrete abutment by a vehicle that veered into his path while he was passing it on the right side. Of interest in deciding the liability in this case is the examination of passing on the right, both by a vehicle driver and a cyclist.

Cyclists are entitled to their share of the highway, just as motor vehicle drivers are. When they are overtaken by a motor vehicle, it is the driver's responsibility to pass the cyclist safely. It is not the cyclists responsibility to get out of the way of the driver if the cyclist is legally occupying the lane.
I was returning to Calgary from Seattle through Trans Canada 1 west of Golden. The road conditions were poor, with a few inches of fresh snow, and visibility was poor due to blowing snow. Traffic had slowed to around 50 km/h. I watched other drivers pass semis behind me which were moving at around 30 km/hm due to the extremely poor visibility from driving behind them.
