Final answer:
Drivers are prohibited from passing on either side of a solid centerline. Traffic signals enhance pedestrian safety and help regulate vehicle speed at intersections, creating a safer environment for all road users.
Step-by-step explanation:
Drivers may not pass from either side of a solid centerline. The purpose of solid centerlines is to indicate zones where passing or crossing to the opposite lane is deemed unsafe due to visibility, traffic conditions, or road configurations. These lines are an essential component of road safety, guiding drivers to navigate the roads while considering the safety of all road users, including pedestrians and cyclists.
Pedestrian Safety:
Pedestrian safety is a significant concern at busy intersections, especially where high traffic volumes and speed can jeopardize the welfare of individuals crossing the street. A traffic signal at such intersections allows pedestrians to cross safely by giving them the right of way at specific times, and also makes vehicles slow down, adhering to speed limits and preventing them from speeding through the signal.
Vehicle Speed Regulation:
Many vehicles tend to ignore posted speed limits, which can lead to hazardous conditions at intersections. By implementing traffic control measures, such as traffic signals or other speed-reducing mechanisms, authorities can help in regulating vehicle speed to maintain safety for all road users.
