Tailgating in driving refers to the practice of following another vehicle too closely, often within a distance that does not allow for safe stopping. This behavior can lead to accidents, as it reduces the time a driver has to react if the vehicle in front suddenly slows down or stops. Many drivers tailgate due to impatience or frustration, especially in heavy traffic. However, it is important to maintain a safe following distance, typically recommended as at least three seconds behind the vehicle ahead, to ensure adequate reaction time and promote road safety.
