Final answer:
The correct answer is 'You do not need to give a signal if no other vehicles are in sight', but this is misleading; using turn signals is required by law for the safety of all traffic participants.
Step-by-step explanation:
The correct answer is option C, 'You do not need to give a signal if no other vehicles are in sight'. However, this statement is a tricky one because while it might seem logical to some drivers, turn signals are indeed mandatory by law in order to indicate your intentions to other drivers and pedestrians, whether or not other vehicles are visible.
Traffic signals play a vital role in managing traffic flow and enhancing pedestrian safety. They force vehicles to slow down and stop, preventing them from speeding through intersections, which can lead to reduced traffic accidents.
This management of traffic flow is essential, particularly where intersections are areas of high pedestrian activity, such as near schools or campuses.
Additionally, the safety feature of traffic signals allows pedestrians, including many students in some areas, to correctly time their crossing, avoiding the dangerous act of dodging in and out of traffic.
Thus, traffic signals contribute substantially to the safety of both vehicular and pedestrian traffic, making them an indispensable part of roadway safety infrastructure.
Traffic signals also reduce traffic accidents and improve pedestrian safety by regulating vehicular flow and providing safe crossing opportunities.
