When is it allowed to make a left turn at a red light?

Making a left turn at a red light is permitted when turning from a one-way street onto another one-way street, provided there are no signs prohibiting such a turn. This rule is designed to facilitate traffic flow in urban areas where one-way streets are common, allowing drivers to make efficient turns without having to stop for a red light, which serves to minimize delays and congestion.

The rationale behind this regulation is that if the road you are turning onto is also a one-way street, the likelihood of conflicting traffic is reduced. Drivers are still expected to yield to pedestrians and other vehicles already in the intersection before completing the turn, ensuring safety throughout the maneuver.

This option is distinct from turning left from a two-way street, where a turn at a red light is not permitted. Furthermore, signage indicating specific hours or restrictions applies to other scenarios but does not affect the general rule regarding left turns from one-way streets.
