Which type of weather condition is likely to require a driver to change their route?

Heavy rain or snow are significant weather conditions that can greatly impact driving safety and road conditions. Such weather can lead to decreased visibility, slower speeds, and the potential for dangerous situations like hydroplaning or poor traction on icy surfaces. In these conditions, roads may become hazardous or even impassable. Drivers often need to adjust their routes to avoid areas that could pose a risk, such as those prone to flooding or heavy snow accumulation. Therefore, altering a route can be a necessary precaution to ensure the safety of the driver and others on the road during severe weather events.
