3 Reasons Why Left Turn Lanes are More Dangerous
1
Left turns are taken at a wider radius, leading to higher speeds, cutting corners too closely and greater pedestrian exposure.
2
The driver's visibility is partially obscured by the vehicle's A-pillar and parked cars.
3
Left turns are more complicated than right turns and require more mental and physical effort.
