Final answer:
The minimum safe distance to leave between a vehicle and a biker is 3 feet. This distance is important for the safety of cyclists. The exact safe distance to wait before crossing in front of a moving car can vary but might be around 5-6 car lengths at suburban road speeds.
Step-by-step explanation:
The distance that must be left between a vehicle and a biker is 3 feet. This is the minimum safe distance that many states and regions have adopted by law to prevent collisions and ensure the safety of cyclists. When a car is overtaking a bicycle, it's essential to provide adequate space to allow for any unexpected movements by the cyclist or potential road hazards. While the safety distance might vary slightly depending on local laws, 3 feet is generally accepted as the standard safe passing distance. Understanding and adhering to this rule as a driver is crucial for the safety of all road users. Note that in situations where road conditions are less than ideal, such as when it's wet, icy, or visibility is poor, giving even more space when passing cyclists can be a prudent decision. As for g, related to how far away a car should be before it's safe to cross, this depends on various factors such as the speed of the vehicle, the conditions of the road, and the pedestrian's assessment of the situation. A rule of thumb is to ensure the vehicle is far enough away that you can cross safely without rush. This can vary, but some sources suggest waiting for a gap equivalent to about 5-6 car lengths when the vehicle is moving at a suburban road speed.
