Final answer:
Road signs are critical to road safety. With increased traffic due to factors like nearby businesses or events, it is important to be vigilant and understand the need for traffic signals for safe crossing, especially in situations where pedestrian safety is a concern.
Step-by-step explanation:
Interpreting road signs is a crucial part of ensuring safety on the roads. When another road enters the one you are traveling on, it is important to watch for traffic from the new direction. Increased traffic at an intersection, such as from a nearby manufacturing plant or due to events like football games, necessitates additional caution and potentially the installation of a traffic signal. Failure to observe and comply with signage can lead to accidents, especially when pedestrian safety is at risk and the volume of traffic has increased significantly.
As a rule of thumb, assessing whether it is safe to cross a road should be based on the speed and distance of oncoming vehicles. If a car is 28 meters away, which is about the length of eight cars, one must consider the speed at which it is traveling before deciding to walk across the road.
