Drivers who are short on time may drive in an aggressive, reckless, or otherwise unsafe manner. Because a truck is so much bigger than a passenger vehicle, truck drivers may tend to drive more aggressively. Some examples of aggressive driving include exceeding the speed limit (making it almost impossible to stop quickly), tailgating smaller vehicles or other trucks, changing lanes in a dangerous manner, or passing due to impatience, failing to adapt driving to adverse weather conditions, or “ganging up” on passenger car drivers with other truck drivers.
