Whenever you want to change lanes, you must check for traffic ______.

• A. In front of the vehicle
• B. Directly behind the vehicle
• C. Behind and to the side of the vehicle
• D. To the rear of the vehicle

Answer: (C)

When you want to change lanes, you must check for traffic behind and to the side of your vehicle. This ensures there are no vehicles in your blind spots or approaching from behind in the adjacent lane, which could lead to a collision if you merge. Relying only on what’s in front or directly behind misses cars in the next lane or in your side view, so you’ll want to glance over your shoulder toward the lane you intend to enter after checking your mirrors and signaling. This combination of checks gives you a safe gap to move into.
