Could a single lane road have a median?

Yes, a single lane road can have a median, although it is less common. Medians are typically used to separate opposing lanes of traffic for safety and can also aid in pedestrian crossings or provide space for landscaping. In some cases, a single lane road might feature a narrow median to enhance visibility or reduce the risk of head-on collisions. However, the width and design of the road must accommodate the median without compromising the road's functionality.
