To be sure a lane is clear before moving into it, you should:

• A. Look in the rear view mirror
• B. All of the above
• C. Look in the left side mirror
• D. Use your mirrors, turn your head and look in the lane you want to enter

Answer: (B)

Before moving into another lane, you should confirm the lane is clear by doing a full around-the-vehicle check. Start with your mirrors to scan for vehicles in the adjacent lanes and in your blind spots, then turn your head to shoulder-check and look directly into the lane you want to enter. Only merge when you’ve verified there’s enough space and no vehicle in that lane. This combination is the safest because mirrors help you see most traffic, but blind spots aren’t visible in them; a quick head turn confirms the lane is truly open.
