Which driving conditions require greater following distances?

Greater following distances are essential in poor weather conditions, heavy traffic, or when driving at higher speeds because these factors significantly affect a driver's ability to react to sudden stops and unforeseen obstacles. In adverse weather, such as rain, snow, or fog, roads can be slick, visibility can be limited, and vehicles may take longer to stop due to reduced traction. Similarly, heavy traffic can lead to abrupt changes in speed and direction from nearby vehicles, requiring drivers to maintain a safe buffer zone for reaction time. Increased speeds also shorten the time available to respond to hazards, necessitating a more substantial following distance to ensure safety. This strategy enhances the likelihood of preventing collisions by allowing ample time to react appropriately to any driving changes ahead.
