How does a heavy load affect braking distance?

A heavy load increases the required braking distance because the overall weight of the vehicle impacts its momentum. When a vehicle is loaded heavily, it becomes more difficult to stop due to the increased inertia. The greater mass means that more force is needed to reduce the vehicle's speed or bring it to a complete stop. Additionally, the braking system has to work harder against the larger weight, causing the brakes to take more time to effectively slow down or stop the vehicle. This is why it is essential for drivers of combination vehicles, especially those carrying heavy loads, to maintain greater following distances and anticipate stopping distances more carefully. Properly accounting for this increased braking distance can enhance safety for the driver and others on the road.
