What does driving on the wrong side of a two-way highway signify?

Driving on the wrong side of a two-way highway signifies endangering other drivers. This action not only violates traffic laws but also creates a hazardous situation for both the driver in violation and other road users. Two-way highways are designed to have clearly defined lanes for vehicles traveling in opposite directions. By driving against the flow of traffic, a driver increases the risk of head-on collisions and other dangerous encounters, making it a significant threat to safety.

The other options are not applicable in this instance. Following traffic rules and obeying local speed limits pertain to responsible driving practices that contribute to safety, whereas driving on the wrong side directly contradicts those principles. Facilitating emergency vehicle passage typically requires driving in a designated manner to clear the road, which is also not applicable when one is driving against traffic.
