The "distancia amigo" or 3-second rule is primarily used to prevent what type of incidents?

The "distancia amigo" or 3-second rule is crucial for maintaining a safe following distance, which specifically aims to reduce rear end crashes. This rule encourages drivers to stay at least three seconds behind the vehicle in front of them under normal driving conditions. By doing so, drivers allow enough time to react to sudden stops or slowdowns of the vehicle ahead.

In the event that the car in front brakes abruptly, having sufficient distance provides the driver with the necessary time to respond appropriately, minimizing the risk of crashing into the rear of that vehicle. This technique is particularly important because rear end collisions are common, and many of these incidents occur due to insufficient stopping distance when a driver is too close to the vehicle in front.

While the other options describe other types of accidents, they are not directly related to the primary function of the 3-second rule. It specifically addresses the danger posed by following too closely, thereby acting as a preventive measure against collisions that occur when the lead vehicle comes to an unexpected stop.
