Why do semis pass each other so slowly?

Why do truckers flash their lights at me?

When a trucker flashes his lights at you, it’s not for nothing. Truckers usually communicate with you using headlights, turn signals and trailer lights. You can quickly flash your headlights when his trailer clears your car, letting him know there is room to move into the other lane.
