In a big city like Toronto, or anywhere for that matter, bicycle accidents are commonly caused by a number of things. This includes dooring incidents, drivers changing lanes without signalling, drivers pulling out of a junction, and poor roadway maintenance.
Dooring occurs when a driver or passenger opens a motor vehicle door into the direct path of a cyclist. Secondly, changing lanes without signalling is extremely dangerous since bicyclists aren’t warned about a driver’s next intentions, causing collisions to occur. A driver pulling out of a junction without fully observing their immediate surroundings is also a common cause of Toronto bicycle accidents. Poor roadway maintenance, such as potholes or otherwise defected tarmac, can also cause a bicyclist to lose traction and flip over.
Elsewhere, driver speeding, traffic weaving, running red lights, failure to yield, impaired driving and driver fatigue all contribute towards Toronto bicycle accidents too.
