3 Reasons Why Left Turns are Dangerous


Left turns are taken at a wider radius, leading to higher speeds, cutting corners closely and greater pedestrian and cyclist exposure.


The driver’s visibility is partially obscured by the vehicle’s A-pillar and/or parked cars.


Left turns are more complicated than right turns and require more mental and physical effort than other aspects of driving.
