Why do you think that truck drivers aren't risking their life for us like the firefighters and police men are doing? We live in a society where most jobs are needed. If it wasn't for them it would be hard for millions of people to get their food in the stores every day.

Edit: to clarify even more, even the truck driver knows thst he's got a probability to die during his work, which seems to be higher than most other jobs. Most drivers know this.
