Final Answer:
A motorist should increase the following distance (make the space cushion bigger) behind vehicles that are larger, carrying heavy loads, or have limited visibility, such as trucks and buses.
Step-by-step explanation:
The concept of following distance is a fundamental element of safe driving practices. The general guideline is to maintain a safe distance from the vehicle in front to allow for reaction time and sufficient space in case of sudden stops or emergencies. This principle becomes even more critical when driving behind larger vehicles, such as trucks and buses. Larger vehicles often require more time and distance to come to a complete stop due to their weight and momentum.
Increasing the following distance behind larger vehicles is essential for several reasons. First, larger vehicles may have longer stopping distances, and allowing a greater space cushion provides the necessary time for a motorist to react to sudden stops. Second, larger vehicles may have limited visibility, creating potential blind spots for the driver. By maintaining a larger following distance, a motorist ensures they have a clear line of sight and can anticipate the movements of the larger vehicle.
In summary, the decision to increase the following distance behind larger vehicles is rooted in the principles of safety and anticipatory driving. It accounts for the unique characteristics of larger vehicles, providing a safety buffer that allows for proper reaction time and visibility. Adhering to this practice contributes to overall road safety and reduces the risk of accidents, particularly in situations where larger vehicles may pose additional challenges to following drivers.
