What is the recommended spacing rule to follow when driving a bus at higher speeds?

The recommended spacing rule of four seconds for every 10 mph is based on the need for ample following distance, especially when driving larger vehicles like buses. Buses take longer to stop due to their size and weight, and maintaining a four-second following distance allows for sufficient reaction time in the event of an emergency. This rule supports safe driving by giving the driver enough time to assess and respond to the situation ahead, helping to prevent collisions.

Furthermore, this spacing guideline takes into account factors such as the speed of traffic, road conditions, and the capabilities of the bus itself. A four-second buffer is considered a safe practice that can accommodate various driving conditions while ensuring passenger safety in the event of abrupt stops or slowdowns. This approach emphasizes defensive driving, allowing a driver to adjust their speed and position in response to the vehicle ahead, which is especially crucial when carrying passengers.
