When are you required to use headlights in Ohio?

Answer: B — From sunset to sunrise and in conditions of poor visibility

In Ohio, the requirement to use headlights is based on visibility conditions and the time of day. Headlights must be used from sunset to sunrise, which ensures that vehicles are visible to others during nighttime driving. Additionally, headlights are also mandated to be in use during conditions of poor visibility, such as rain, fog, or snow, regardless of the time of day. This is crucial for safety, as good visibility can significantly reduce the risk of accidents. Using headlights in these specific conditions helps other drivers see your vehicle, making it easier for them to react appropriately. Therefore, the combination of night driving and reduced visibility due to weather conditions is why this choice is correct and reflects Ohio law on the use of headlights.
