What if it was forbidden to turn left?
Urban design plays a crucial role in shaping the liveability of cities. With increasing population density and traffic congestion, cities are facing major mobility challenges that can lead to traffic accidents, increased pollution and a general reduction in the quality of life for residents. One potential solution to this problem is the ban on left turns.

What if it was forbidden to turn left?
Urban design plays a crucial role in shaping the liveability of cities. With increasing population density and traffic congestion, cities are facing major mobility challenges that can lead to traffic accidents, increased pollution and a general reduction in the quality of life for residents. One potential solution to this problem is the ban on left turns.
Is it really a problem to turn left?
Left turns are a common cause of traffic accidents, as they require drivers to cross multiple lanes of traffic and often result in collisions. In many cities, up to 40% of traffic accidents involve left turns. By banning left turns, cities can help to reduce the number of traffic accidents and improve road safety for all road users.
A way to improve traffic flow (UPS)
Reducing left-turns improves traffic flow, reduces travel times, and leads to cleaner cities. UPS's change in delivery routes, reducing left-turns, saves fuel and reduces carbon emissions, increasing package delivery. This modest change saves 40 million liters of fuel, reduces 20,000 tons of carbon emissions and allows for the delivery of 350,000 additional packages annually.
The alternatives? Design safer intersections
To address this problem, the San Francisco Municipal Transportation Agency (SFMTA) has launched the Safer Intersections Project to address issues of traffic safety and intersection design. The project involves testing innovative approaches to intersection design and a public education campaign funded by a $2 million grant. The goal of this campaign is to reduce unsafe driving practices. This initiative is part of the city's Vision Zero plan, which aims to eliminate all traffic fatalities.
The consequences are good for cities and the environment
In addition to these benefits, a ban on left turns can also encourage more sustainable forms of transportation, such as walking, cycling, and public transportation. By reducing the number of cars on the road, cities can create more space for these alternative modes of transportation, making it easier and safer for people to choose them over driving.
Implementing a ban on left turns in cities has benefits in reducing traffic accidents, improving traffic flow, and reducing air pollution. However, there are challenges in implementation such as potential negative impact on local businesses and the need for re-education of drivers. Despite these challenges, the benefits make a ban on left turns a worthy consideration for cities.
