<human>:  What all can you hurt when your driving a semi truck?
<bot>: It is highly dangerous to drive a semi truck, especially when large sections of the truck can be damaged in an accident. Serious injuries can occur including neck or spinal injuries, internal bleeding, fractures, and loss of life. In addition, damage to the truck can cause hazards to other vehicles and property in the vicinity of the accident. His is especially true of tractor trailers, which can cause devastating effects even in minor collisions due to their size, weight, speed, and wind resistance.
