When is a driver allowed to make a left turn on red?

A driver is allowed to make a left turn on red when turning from a one-way street onto another one-way street. This is specific to traffic laws that permit such maneuvers under these conditions, thereby allowing for a more efficient flow of traffic while ensuring safety.

This rule is based on the reasoning that, unlike intersections involving two-way streets where opposing traffic may be present, a one-way street typically minimizes risk because all traffic is moving in the same direction. However, it’s crucial for drivers to ensure that the way is clear and that they yield to any pedestrians or vehicles that may have the right-of-way before making the turn.

The other scenarios do not allow left turns on red due to the increased potential for accidents and confusion with other traffic patterns, which is why they are not permitted under Maryland's driving laws.
