What does a solid yellow line indicate when riding a motorcycle?

A solid yellow line indicates that no passing is allowed for vehicles, including motorcycles. This marking serves as a warning to riders that the road conditions may not be safe for overtaking other vehicles. The presence of a solid yellow line often signifies that visibility is limited or that the roadway has specific characteristics such as curves or hills that could make passing dangerous.

Riders should adhere to this marking because attempting to pass in such situations could lead to accidents or hazardous encounters with oncoming traffic. It's essential for motorcycle operators to recognize these road markings to make safe and informed decisions while riding.
