That’s not true I’ve met several people who killed someone while driving a truck and they are just fine.
1) Driver finishes his 10 hour break, pretrips the truck and then walks into the truck stop to use the bathroom. Comes back, checks the mirrors and then pulls out. As he’s leaving the truck stop he sees people flagging him down so he stops.
A mentally retarded worker (not a joke, actually retarded) was cleaning the parking lot and crawled down by his tandems to pick up trash and was killed. The D.A. looked at it but declined to prosecute. When the D.A. didn’t prosecute, the company decided not to punish the driver either.
2) Flash rainstorm and a motorcyclist driving beside a truck in the passing lane lost control and went under the tandem wheels of the driver I knew. Same story. D.A. declined to prosecute and the company didn’t punish him either.
