Final answer:
At an intersection with no signs or signals, you must yield to vehicles already present or when entering a busier road. Traffic signals are essential for controlling vehicle speeds and ensuring pedestrian safety, and their absence can lead to unsafe conditions and increased accidents.
Step-by-step explanation:
When you come to an intersection that has no traffic signs or signals, you must yield the right of way if there are vehicles already in the intersection or if you're entering a more congested roadway. It's critical to understand the importance of traffic safety and the role traffic signals play in maintaining order and preventing accidents.
Vehicle speed at intersections can often exceed the posted speed limit, creating hazards for other drivers and pedestrians. A traffic signal forces vehicles to slow down, making it safer for everyone. Specifically, in areas heavily trafficked by pedestrians, like near a campus, traffic signals can assist in managing safe crossings.
In cases where the safety of pedestrians and drivers has been compromised, as seen with the increased number of accidents in recent reports, the installation of a traffic signal becomes a compelling necessity. Not only do traffic signals help manage vehicle speeds and pedestrian crossings, but they also significantly reduce the likelihood of accidents, some of which may be fatal.
