Is it permissible to turn from a Two-way Street onto a One-way street?

Turning from a two-way street onto a one-way street is permissible and is a common maneuver that drivers often execute. When making this turn, it is important to ensure that the driver is aware of the traffic and any pedestrians in the area, and that they turn in the direction of the traffic flow of the one-way street. This allows for a safe and efficient transition onto the one-way street without disrupting other vehicles or pedestrians.

Other options suggesting that the turn is not allowed at all, or only permitted under specific conditions or with permission, are not accurate. The act of turning onto a one-way street from a two-way street is straightforward, provided that all traffic laws are followed, thus making it permissible as long as it is done safely.
