In which situation should you lower your speed?

Lowering your speed in adverse weather conditions is crucial for maintaining safety while driving. Weather conditions such as rain, snow, fog, or ice can significantly affect road traction and visibility, making it harder to control your vehicle. Reduced speed allows for better reaction time to unexpected changes, such as skidding or suddenly needing to stop. Additionally, lower speeds can help you maintain control over your vehicle, decreasing the likelihood of accidents.

In contrast, entering a highway typically requires increasing speed to match the flow of traffic, whereas open roads with little to no traffic may allow for maintaining a normal speed. Driving past a filling station, while it may necessitate some vigilance due to potential pedestrian traffic, does not inherently require reducing speed in the same way that adverse weather demands caution and a controlled approach. Thus, the correct focus is on adjusting speed in response to adverse driving conditions for optimal safety.
