What is a consequence of driving with a full load?

1. Increased stability

2. Improved acceleration

3. Longer stopping distance

4. Better fuel economy

The correct answer is: Longer stopping distance

When driving with a full load, one significant consequence is the longer stopping distance. A full load adds extra weight to the vehicle, which in turn increases the momentum of the vehicle. As a result, it requires more time and distance for the vehicle to come to a complete stop. This is due to the increased kinetic energy that needs to be dissipated when braking. Drivers must therefore anticipate this longer stopping distance, especially in situations where quick braking is necessary, such as in emergencies or when approaching traffic signals. Increased stability can be a factor with the right conditions and vehicle design, but it is not universally guaranteed with a full load. Similarly, while some vehicles may improve their fuel economy under certain conditions when loaded, this is not a general rule and often depends on several external factors. Improved acceleration is typically hindered by a full load as the extra weight requires more power to achieve the same speed, countering any benefits that might arise from a vehicle's design for heavier loads. Hence, longer stopping distance accurately reflects a fundamental consequence of driving with a full load.
