Final answer:
Safe overtaking requires leaving at least one to 1.5 meters of space between a car and a biker, considering reaction times, braking distances, and road conditions. Drivers should adjust this distance according to speed and environmental factors to ensure safety.
Step-by-step explanation:
When passing a biker on the road, it is crucial for the safety of the biker and the car occupants to maintain an appropriate distance. While the specific distance can vary by jurisdiction, a common guideline is to leave a minimum of one meter or about three feet of space between the car and the biker. In some places, the law may require more distance, such as 1.5 meters or five feet. When considering stopping distances, a car traveling at 60 km/hr will cover more distance than just the length of the car itself, due to reaction time and braking distance. Road conditions, such as wet or dry pavement, also significantly affect the required distance to stop safely.
The distance for safe overtaking should accommodate these factors and ensure that the car can pass without posing a risk to the biker. Drivers should also consider the speed at which they are traveling and the potential for sudden movements from the biker. As passing involves changing lanes and possibly encountering other vehicles, driver reaction time and the ability to judge distances and speeds accurately are essential for a safe maneuver.
