When is it permissible to turn left on red?

It is permissible to turn left on red when you are on a one-way street and you are turning onto another one-way street. This rule is in place to allow for greater traffic flow in specific situations where it is safe to do so. When making this turn, drivers must ensure that there are no oncoming traffic and that it is safe to proceed, essentially treating the left turn on red similarly to a right turn on red at a stoplight.

In contrast, turning left on red is not allowed in all circumstances, such as from a two-way street or where signs explicitly prohibit it. Always ensuring that the intersection is clear before making the turn is crucial for safety.
