On a multi-lane highway, under normal circumstances, which lane should slower traffic use?

• The left-most lane
• The travel lane furthest to the right
  Explanation:

  "On a multi-lane highway, slower traffic should use the travel lane furthest to the right unless preparing for a left turn. This helps maintain smooth traffic flow and prevents congestion in faster lanes."
• Any lane you want to travel in
• The lane you are already traveling in
