Explanation
When passing a large vehicle such as a truck, don't merge back in front of the vehicle until you can see its headlights in your rear-view mirror. (Some authorities recommend waiting until you can see the entire front of the vehicle in your rear-view mirror.) Large vehicles have long stopping distances. If you merge back directly in front of a large vehicle and then suddenly slow down or stop for some reason, you might get rear-ended by the large vehicle.
