Left Turns Are Dangerous on City Streets, A Case to Restrict Them.

Left turns in city streets are dangerous and slow down traffic, according to a professor. Left turns are responsible for a significant number of traffic crashes at intersections. While there are different methods to handle left turns, such as waiting for an opening or using a left-turn arrow, both methods have drawbacks. The professor suggests banning or heavily restricting left turns in downtown areas to improve safety and reduce delays. This approach requires no infrastructure changes and has been implemented in several cities already. [Extracted from the article]
