Final answer:
In traffic, left-turning vehicles must yield the right-of-way to vehicles going straight and should only proceed when safe or wait for a protected signal.
Step-by-step explanation:
When vehicles are turning left, they must yield to vehicles going straight. This means they do not have the right-of-way and should either stop and wait for a protected signal or proceed with caution only when it is safe to do so. Vehicles speeding through an intersection may pose a danger to both other vehicles and pedestrians. The installation of a traffic signal can help regulate vehicle speeds and create safer conditions for pedestrians to cross, reducing the need to dodge traffic. Left-turning vehicles should be especially mindful of pedestrian safety.
