California Driver License (DMV) Written Practice Test

When can you turn left at a red traffic light?

1. When turning from a one-way street onto another one-way street.

2. When there is a sign permitting left turns on red.

3. When the way is clear and there is no oncoming traffic.

4. Left turns are never allowed on a red light.

The correct answer is: When turning from a one-way street onto another one-way street.

Turning left at a red traffic light is permitted under specific conditions, and one of those conditions is when turning from a one-way street onto another one-way street. This rule helps facilitate the flow of traffic and minimizes unnecessary stops when it is safe to make such a maneuver. When making this turn, it is still essential to ensure that the way is clear, meaning you must check for oncoming traffic and pedestrians, ensuring that you follow all the same safety protocols as you would at any intersection. This specific regulation acknowledges the context of urban driving where one-way streets are common, allowing drivers to navigate more efficiently while maintaining safety. Other options might suggest situations where left turns are allowed or discuss general traffic conditions, but these do not fit the established legal conditions under which a left turn on red is permissible.
