Why should a tanker driver maintain a greater following distance?

A tanker driver should maintain a greater following distance primarily to account for longer stopping distances and the need for maneuvering, particularly when transporting liquid cargo. Tankers carry large volumes of fluid, which can shift and affect the vehicle's stability and braking characteristics. When the tank is full, the stopping distance increases significantly due to the weight and momentum of the liquid. Additionally, if the driver needs to react quickly to a changing situation on the road, having a larger buffer zone allows for safer maneuvering without risking a collision, especially in emergencies. This increased following distance is essential for ensuring not only the driver's safety but also the safety of others on the road as the dynamics of driving a tanker are different from driving a standard vehicle.
