Why should you avoid making quick, last-second lane changes when driving a combination vehicle?

Pick an answer

1. Lane changes only affect fuel economy, not safety, for a combination vehicle
2. Quick lane changes save the most time and are preferred once traffic allows it
3. The trailer automatically corrects its position regardless of how quickly or slowly the lane change is made
4. The trailer needs the full width of the new lane and more time to complete the move safely behind the tractor
