Final answer:
Large vehicles should activate their blinker before reaching the intersection to ensure the safety of all road users, enhance pedestrian safety, and prevent accidents.
Step-by-step explanation:
At an intersection, large vehicles should activate their blinker well before they reach the point of turning to allow other drivers, pedestrians, and cyclists ample time to be aware of their intent to turn.
This is particularly important as large vehicles require more distance to slow down and make a turn safely. Activating the blinker early helps ensure the safety of all road users and contributes to the smooth flow of traffic.
Pedestrian safety is greatly enhanced by vehicles signaling their turns because it alerts those on foot to changes in traffic patterns, allowing them to cross at safer times.
Furthermore, the use of blinkers can prevent accidents, an issue that becomes even more significant in areas with a high rate of traffic incidents or where traffic has increased due to new businesses or changes in traffic routing, such as around a college campus on game days.
