What should you do when following a truck on the freeway?

Answer: A — Follow at a safe distance

It is important to follow at a safe distance behind trucks on the freeway in order to avoid potential hazards. Tailgating or driving too closely behind a truck can increase the likelihood of a collision, especially if the truck needs to make a sudden stop. Changing lanes more often or driving closer than other vehicles is also not recommended as it can disrupt the flow of traffic and increase the risk of accidents. Therefore, the best option is to maintain a safe distance behind the truck at all times.
