36% of all traffic accidents occur in intersections during a left-hand turn according to the National Highway Traffic Administration.
Left-hand turns account for more than twice as many pedestrian and bicyclist fatalities as right-hand turns and over three
times as many serious injuries.
of All Traffic Accidents Occur in Intersections During a Left-Hand Turn

Left turns are taken at a wider radius, leading to higher speeds, cutting corners too closely and greater pedestrian exposure.
The driver's visibility is partially obscured by the vehicle's A-pillar and parked cars.
Left turns are more complicated than right turns and require more mental and physical effort.
