Final answer:
Wide white lane lines indicate that changing lanes is hazardous, and one should cross them with caution. Pedestrians must calculate the necessary safe distance before crossing, considering car speeds and lane width. Public safety is paramount, especially at busy intersections, and compliance with traffic signals is crucial to pedestrian safety.
Step-by-step explanation:
White lines on the road indicate traffic lanes and provide important information about lane usage and vehicle positioning. When the white lines are wide, it suggests that lane changes are hazardous.
To determine whether it is safe to cross multiple lanes of traffic, such as for a pedestrian or a car entering a roadway, one must assess the speed and distance of oncoming traffic. For example, in towns and cities where the speed limit is generally 60 km/h, the distance needed to safely cross in front of an oncoming vehicle will be greater than in slower speed areas. One must ensure they can cover a distance greater than the width of the car (at least 4 meters) before the car reaches their position.
Pedestrian safety is a critical issue, and at busy intersections near campuses or other areas with heavy foot traffic, it is vital to observe traffic signals and crosswalks to ensure safe crossing. Factors like vehicles speeding or not adhering to traffic signals make crossing more dangerous, so pedestrians must be vigilant.
