When passing a truck, do not pull back in front of it until you can see

Explanation

Trucks require a much longer stopping distance. Do not enter a roadway directly in front of a large vehicle. When passing a large vehicle such as a bus or truck, do not pull back in front of it until you can see the vehicle's cab in your rear-view mirror. Don't make sudden stops directly in front of large vehicles. If you pull right in front of a large vehicle and then slow down or stop suddenly, you might get rear-ended by the large vehicle.
