Final answer:
True, lights and signals rules must be observed in any weather to maintain safety. These rules are essential for controlling vehicle speed at intersections and protecting pedestrian crossings.
Step-by-step explanation:
True, lights and signals rules must be followed in all weather conditions. These rules are in place to ensure that vehicles can navigate intersections safely and effectively. When vehicles disregard the set speed limits and signals, it increases the chances of accidents and jeopardizes pedestrian safety. For example, the presence of a traffic signal ensures that vehicles slow down in time and stop when necessary, reducing the likelihood of speeding through an intersection. It also allows pedestrians to cross at designated times rather than having to dodge traffic. There are special emergency scenarios where breaking a signal rule may be considered, such as when a pregnant woman needs urgent transport to a hospital, but these are exceptions.
