Final answer:
The question pertains to road safety, highlighting that except on multi-lane roads, passing in certain areas such as hills, curves, intersections, or railroad crossings is unsafe and illegal. Traffic signals help regulate vehicle speed and facilitate pedestrian crossing in high-risk areas.
Step-by-step explanation:
Understanding the rules of the road is essential for ensuring both safe driving practices and pedestrian safety. The statement you've encountered rightly suggests that with exception of roads with multiple lanes, passing on hills, curves, at intersections or railroad crossings is typically both unlawful and unsafe. These traffic regulations are put in place to reduce the risk of accidents and enhance safety for all road users.
Intersections, in particular, are hotspots for potential traffic hazards. To manage traffic flow and improve safety, traffic signals are often installed. These signals force drivers to slow down and can regulate the crossing of pedestrians, thereby reducing the likelihood of accidents. Pedestrians, especially in busy areas such as school zones or campus crossings, benefit significantly from the presence of traffic signals, which allow them to cross roads without having to dodge incoming vehicles.
Driving behavior like speeding can be mitigated by these signals, as drivers are aware that they could be held at a red light, which discourages excessive speed. Pedestrian and driver educational programs also emphasize the importance of following set speed limits, especially in urban areas where pedestrian crossings are common. For road safety, both drivers and pedestrians are reminded of the need to be aware of their surroundings and comply with road regulations.
