Under what condition may you turn left at a red traffic light from a one-way street onto another one-way street?

Turning left at a red traffic light from a one-way street onto another one-way street is generally permitted when local laws allow it, provided there are no signs indicating that such a turn is prohibited. This regulation is in place because it facilitates the flow of traffic in situations where left turns would otherwise be allowed at a standard intersection and is safe to do so.

For this maneuver, the driver must also ensure that they yield to any oncoming traffic, cyclists, or pedestrians before making the turn. If there are no posted signs restricting this action, it indicates that it is lawful and permissible under those conditions. Therefore, understanding the specific signage and regulations in place at an intersection is crucial for safe driving practices.
