What do double yellow lines indicate on the road?

Double yellow lines on the road indicate that no passing is allowed in either direction. This marking is used to enhance safety by clearly signaling to drivers that they should not cross these lines for the purpose of overtaking another vehicle. The presence of double yellow lines typically suggests a no-passing zone, often due to limited visibility, changing road conditions, or high traffic areas where passing could lead to dangerous situations.

This road marking helps maintain order on the roadway and protect both drivers and pedestrians. Understanding this rule is crucial for safe driving, as attempting to pass in such zones can result in fines and increased risks of accidents. Other road markings, such as single yellow lines or dotted lines, convey different rules regarding passing, but double yellow lines specifically enforce that overtaking is prohibited in both directions.
