Okay, no - not all truck drivers look like this... because some of them are women. That wasn't very nice, and I only say it because I'm tired of sitting behind truck drivers who pass each other going uphill on the freeway at half the speed limit. Just so you truckers know, though 32 miles an hour is wrecklessly fast in a school zone, it's probably not fast enough to require you to block the freeway's passing lane for ten minutes while you gently sneak by the guy who's going 30.
Driving a truck would be one of the worst jobs I can imagine. I experience plenty of road rage just driving to work... if driving was work, the rage would never subside. That giant mug is based on my own 64-ouncer that I used to fill with Cherry Coke at least once a day. I switched to water when I realized I was beginning to look like this gentleman.
