What is a common safety measure during rainy conditions?

Using headlights as necessary during rainy conditions is an important safety measure because it enhances visibility for both the driver and other vehicles on the road. Rain can create hazards such as reduced visibility due to water on the windshield, glare from other vehicles, and the presence of mist or fog. By turning on the headlights, drivers can ensure that they can see the road and any obstacles clearly, as well as be more visible to other drivers. This practice is not only a good safety habit but is often legally mandated in many areas when visibility is poor due to weather conditions.

In contrast, decreasing the use of headlights, driving with high beams on, or avoiding the use of windshield wipers are counterproductive in rainy conditions. Each of these alternatives fails to address the primary concern of visibility, which can lead to dangerous driving situations. Using headlights appropriately helps mitigate these risks and is crucial for safe driving in adverse weather.
