What does a solid double yellow line indicate?

A solid double yellow line indicates that no passing is allowed for vehicles traveling in either direction. This marking is placed on the road to ensure safety and is commonly used in areas where visibility is limited or where passing could create unsafe conditions, such as on hills or curves. Because of this, drivers must remain in their lanes and cannot cross the double yellow line to overtake another vehicle. Understanding this road marking is essential for maintaining proper safe driving practices and adhering to traffic regulations.
