When must headlights be used according to Maryland law?

Headlights must be used in adverse weather conditions, regardless of the time of day, to ensure maximum visibility and safety on the road. This includes situations such as rain, snow, fog, and anything else that creates reduced visibility. Maryland law emphasizes the importance of using headlights to help not only the driver see better but also to make the vehicle more visible to other drivers and pedestrians.

This requirement is particularly significant because adverse weather conditions can significantly impair visibility, increasing the likelihood of accidents if proper precautions are not taken. Using headlights in these situations helps to enhance safety for all road users.

While headlights are typically associated with nighttime driving, they are also crucial in daylight during poor weather conditions, hence the necessity for their use in those situations.
