Turns, Lanes, Passing & MergingStandalone practice
You drive in the left lane of a four-lane highway and want to move into the right lane. Your mirrors show that the right lane is clear. What should you do before you move over?
A travels in the left lane of a four-lane highway. The adjacent right lane appears empty, and no lane-change path is selected.
Correct answer: Signal, turn your head to check the blind spot, then move only if clear.
Why
On a road with marked lanes, keep your vehicle within one lane. Leave it only after you have checked your mirrors, signaled and looked over your shoulder toward the lane you want. Check quickly and look ahead again, because traffic in front of you can stop while you look to the side.
