The device used on some highways to direct drivers into the proper lanes for turning is white arrows painted in the middle of the lanes on the pavement.

What the question is asking

This is a classic driver’s license / permit-test style question that refers to pavement markings used to show which lane you must be in to turn right, left, or go straight.

  • These markings appear directly on the road surface.
  • They typically show arrows pointing left, right, straight, or a combination (e.g., left-and-straight).

Why the answer is white arrows

  • Pavement arrows indicate the allowed direction of travel from that lane, such as “left turn only” or “right turn or straight.”
  • DMV-style practice questions that use the wording “are used on some highways to direct drivers into the proper lanes for turning” give the correct choice as “white arrows in the middle of the lanes.”

How these arrows help drivers

  • They guide you early so you can get into the correct lane before reaching the intersection.
  • They reduce confusion and sudden lane changes , which helps prevent crashes at busy junctions and highway exits.

TL;DR: When you see this exact phrasing on a test, choose “white arrows in the middle of the lanes.”
