Final answer:
Drivers should signal for at least 100 feet before turning or stopping. Signaling helps with pedestrian safety and managing vehicle speeds. Signals must be turned off after the turn is complete to avoid confusion on the road.
Step-by-step explanation:
The question pertains to the rules of the road, specifically how long a driver should signal before making a turn or coming to a stop. Although the exact distance required can vary by state or country, it is often required to signal at least 100 feet before turning or stopping to allow other drivers and pedestrians ample warning of your intentions. Turning off your signal lights after the turn is complete is also essential to avoid confusion among other road users.
Factors such as pedestrian safety and vehicle speed can impact when and how signals are used. For instance, traffic signals can provide structured crossing times, thereby reducing the need for pedestrians to dodge traffic. Additionally, the presence of a traffic signal can help moderate vehicle speed, especially in areas where vehicles tend to disobey the speed limit.
