Final answer:
It is unsafe to pass other vehicles during adverse weather conditions due to reduced visibility and traction. Always keep headlights on, maintain a safe distance, and be prepared to react to pedestrians and changes in the road environment.
Step-by-step explanation:
We should avoid passing other vehicles in rain, snow, or other dangerous weather conditions because these environments can significantly reduce visibility and traction, making it difficult to react to unexpected situations. In heavy rain, for instance, the roads become slippery, and the distance required to stop your vehicle increases. During snowfall, besides reducing grip, snow can obscure lane markings and create unexpected obstacles.
It is important to maintain a safe following distance and keep your headlights on during such conditions to improve visibility. Observing the behavior of others on the road is also critical; for example, if you see a woman pushing a baby stroller down the street, it is essential to slow down and ensure you have the time to react safely to any potential hazard. When it comes to rivers swollen from heavy rain, as another example, it is important to wait until the water subsides before attempting to ford it. Rapid currents and unseen debris can pose serious risks to safety.
