Final answer:
True, drivers must stop at a green light if there is not enough space on the other side of the intersection to prevent blockages. Traffic signals help manage traffic flow and enhance pedestrian safety.
Step-by-step explanation:
The statement is true. Traffic laws stipulate that at a green light, drivers must ensure that there is enough space on the other side of the intersection before entering. This is to avoid getting trapped in the intersection if the light changes to red, which could obstruct cross traffic and create gridlock.
Pedestrian safety is also a crucial consideration at intersections. Installation of traffic signals at busy intersections helps in managing the flow of vehicular traffic and provides pedestrians with safe crossing opportunities, as signals clearly demarcate when it's appropriate to cross.
