Final answer:
The statement 'You may not enter an intersection unless there is enough space to allow passage of other vehicles' is true, reflecting a basic traffic rule designed to prevent congestion and promote road safety. Traffic signals play a key role in controlling vehicle speeds and ensuring pedestrian safety, especially in high traffic areas.
Step-by-step explanation:
The question pertains to road safety and traffic laws, focusing on the right-of-way rules at intersections. The statement in the question implies that a driver should not enter an intersection unless there is sufficient space to cross it without obstructing other vehicles. This is essential to prevent traffic congestion and accidents. The answer to the question is true, as it is a fundamental rule of the road that ensures all vehicles can pass safely and efficiently.
When vehicles speed through intersections, they put pedestrians and other motorists at risk. The introduction of a traffic signal can force vehicles to slow down, adhering to the speed limit and creating a safer environment for all road users, including pedestrians who need to cross. Vehicle speed management and pedestrian safety are crucial components of traffic engineering and urban planning to minimize the chances of collisions and improve overall safety.
Furthermore, proper adherence to traffic signals aids in the smooth flow of traffic and allows for safer pedestrian crossings. In areas with high foot traffic, such as near schools or campuses, the importance of traffic signals is even more pronounced. Pedestrians rely on these controls to navigate the roads without having to 'dodge' vehicles, significantly decreasing the risk of accidents.
