When a large commercial truck makes a right-hand turn, the truck must swing out far to the left in order to negotiate the turn. If the trucker does not see a vehicle in the blind zone on the left side, the passenger vehicle could be squeezed between the truck and the curb, resulting in a serious accident. Passenger vehicles who pass a truck should do so quickly and safely, lingering in the trucker’s blind zone for the least amount of time possible.
