When driving on the right side of a roadway with four or more lanes and two-way traffic, which action is prohibited?

Driving left of the center in a roadway with four or more lanes and two-way traffic is prohibited because it violates traffic laws designed to ensure safety and proper vehicle flow. In a typical configuration for such roadways, the left lane is reserved for vehicles traveling in the opposite direction and for passing. Therefore, vehicles should always remain on their designated side, respecting the center line. Crossing this line can lead to collisions, as it indicates an intrusion into the opposing lane of traffic.

In addition to safety considerations, maintaining compliance with these traffic rules helps facilitate smoother traffic flow and prevents confusion among drivers. While driving in the left lane, stopping in it, or certain maneuvers might be permissible under certain conditions, driving left of the center is inherently dangerous and explicitly against the rules established for the roadway.
