Final answer:
The required minimum distance to safely pass from an intersection, RR crossing, bridge, or tunnel is calculated based on speed limits, vehicle lengths, and required crossing distances. A pedestrian needs to be able to walk at least 4 meters before an oncoming vehicle reaches them, and drivers should maintain multiple car lengths distance from road hazards for safety. Laws regarding passing distances vary by area.
Step-by-step explanation:
The minimum distance one should maintain from an intersection, railroad crossing, bridge, or tunnel to pass safely depends on various factors such as speed limit, visibility, and road conditions. When considering a scenario with a speed limit of 60 km/h as in towns and cities, calculations for safe crossing distances can be based on car lengths. An average car length is approximately 3.5 meters. To cross safely, a pedestrian should have enough time to walk at least 4 meters (2 meters further than the width of an average car), before the oncoming vehicle reaches the pedestrian's path.
If you're traveling by car and planning to execute a maneuver such as overtaking or crossing, it's essential to ensure you are far enough from any of the mentioned road features to have the required visibility and time to react to any potential hazards. As a rule of thumb, it's often recommended to maintain several car lengths worth of distance, although specific laws might dictate the exact required distances, which can greatly vary by jurisdiction.
