You are driving in urban traffic on a dry roadway in a stream of traffic travelling at a speed of 50 km/h. What is the minimum safe distance you must keep from the vehicle in front?

In urban traffic at a speed of 50 km/h, the general rule for maintaining a safe following distance is to keep approximately 1 meter for every kilometer of speed, which translates to at least 50 meters under ideal conditions. However, in certain scenarios, such as heavy traffic or variable conditions, other factors can come into play.

The answer choices provided are simplified estimations. A safe distance can vary based on factors like vehicle type, road conditions, and weather. For urban traffic, a distance of about 15 meters (approximately 3 car lengths) is a good rule of thumb to provide enough braking distance and reaction time.

In practice, always ensure you adjust your following distance as needed based on the situation. This helps prevent accidents and ensures safety for yourself and others on the road. Proper distance also allows for the unexpected actions of the vehicle in front.
