Why is it essential to plan your exit ahead on an expressway?

Planning your exit ahead on an expressway is essential primarily to avoid sudden stops and lane changes. When drivers are aware of their upcoming exit well in advance, they can make smoother transitions and adjustments, reducing the risk of abrupt movements that can lead to accidents. Being prepared allows you to signal your intentions early, merge safely into the appropriate lane, and encounter less stressful driving conditions.

This foresight contributes to overall traffic safety, as it minimizes the likelihood of creating hazards for yourself and other drivers. It also helps maintain a steady flow of traffic on the expressway, which is vital for both safety and efficiency. The other options do not prioritize safety and traffic flow in the same way, making them less relevant to the core objective of safe expressway driving.
