Final answer:
It is legal to make a left turn on a red light from a one-way street to another one-way street after stopping and yielding. Traffic laws may be broken in emergencies to prevent harm. Traffic signals are essential for safety in high-risk intersections.
Step-by-step explanation:
In the United States, it is typically legal to make a left turn on a red light only from a one-way street onto another one-way street, provided that you come to a complete stop first and yield to all other traffic and pedestrians. The legality of this maneuver can vary by jurisdiction, so it is essential to be aware of the specific traffic laws where you are driving. In emergency situations, like when a pregnant woman is about to deliver, laws such as these may be broken if doing so prevents greater harm. With pedestrian and vehicular safety at stake, the installation of a traffic signal is important in high-risk intersections to regulate traffic flow and reduce the number of accidents.
