Stress is simply a reaction to a stimulus that disturbs our physical or mental balance. In other words, it is a natural part of life. As a truck driver, you deal with stress day in and day out.
Trucking is stressful! You have to deal with time commitments, traffic, difficult customers and drivers that think they own the road - even though they are in a smaller vehicle than you. It happens all the time, and there is no way of avoiding it. But you can manage it.
