What should you do if you see a solid white line while riding a motorcycle?

Seeing a solid white line while riding a motorcycle indicates that you should not change lanes. Solid white lines are used to signify lane boundaries and convey that crossing these lines is prohibited, which helps maintain safe traffic flow and reduce the risk of accidents. This rule applies to all types of vehicles, including motorcycles, as it ensures that riders stay in their designated lane, making it easier for other drivers to predict movements on the road. Adhering to this guideline promotes safer riding conditions and helps avoid potential conflicts with other vehicles.

The other choices do not align with safe riding practices: passing where it is not allowed can lead to dangerous situations, ignoring the line could result in unintended lane changes that jeopardize safety, and increasing speed while crossing a line can decrease control and the ability to react to obstacles or other road users.
