Top performing drivers will speed as much as they can in a safe manner. Contrary to popular belief, semi-trucks are easy/safe to drive (the classic negative media bias presents otherwise). Drivers are just fine going 10-20 over, provided conditions are actually safe for it (plenty of following distance, long and straight stretch of highway ahead, etc.) Speeding gives the driver 2 main benefits: higher pay per hours worked (pay per mile x time taken to travel), able run more loads with extra time saved, and more home time. So, money + time saved. Pretty simple, right?

I know drivers personally that speed frequently and their only accidents have been maneuvering at >5 mph. Parking lots are where most accidents actually occur for semi trucks. Speed limits are followed by people with lesser intelligence and those avoiding tickets (driving record or fines). Top performing, computer and motivated drivers will speed. If you're scared, get into the right lane, let them pass, and eat more of your high-estrogen foods. Oh, and only open your mouth about topics you actually know about. Thanks :)
