How should you perform a proper lane change in a commercial vehicle?

• A. Do not signal when changing lanes.
• B. Check mirrors, signal, check blind spots, and execute the lane change smoothly.
• C. Signal after completing the lane change.
• D. Check blind spots only after the lane change.

Answer: (B)

When you change lanes in a commercial vehicle, you must communicate your intent, verify there’s a safe gap, and move smoothly. Start by checking your mirrors to see traffic in and behind the lane you want to enter. Then give a clear signal well before you move so other drivers know what you’re planning. Do a quick shoulder or head turn to check the blind spots, because large trucks have big areas that mirrors can’t fully cover. If the lane is clear, steer gently into the new lane and maintain a steady speed so the maneuver is smooth and predictable for other drivers and for your own stability, especially since a heavy vehicle needs more space to compensate for wind, road conditions, and momentum. Not signaling or signaling too late deprives others of warning, increasing the risk of a sudden or misjudged move. Waiting to check blind spots until after you’ve begun the lane change means you could enter a space that isn’t actually clear.
