Why does my car shake when I am behind a tractor trailer?

The only time my car shakes is when behind a big truck.

If you are directly behind a tractor trailer moving at a high speed on the highway, your vehicle is in the airflow turbulence zone caused by the big rig. That can shake your car if you are at a certain distance.

Due to the huge size of tractor trailers and traveling at high speeds, the wind is pushed around it. Then there is the space between the back of the truck and your car causing a gap/lull in wind pressure which allows the wind to slam into your car.
