Trucking is a dangerous industry. Tractor-trailer drivers have the highest number of nonfatal injuries and illnesses that require days off from work across all occupations. Many people think that trucker safety is only about preventing crashes. But there are other dangers that are mostly invisible.

No one thinks of a truck cab as having plenty of space. With the push to make vehicles more fuel efficient, trucks are getting even smaller. This means cramped quarters for drivers. Taller-than-average drivers can suffer musculoskeletal injuries from being forced to stoop in constrained spaces.

Technology has led to big increases in productivity across the trucking industry. But it also causes repetitive-use injuries. Drivers must input data using small keyboards or touch screens without enough space or wrist support. This has led to a rise in carpal tunnel syndrome in drivers, even though most people only associate the condition with office workers.

There are some things drivers can do to protect themselves. Changing your seat position at least once an hour can prevent injuries. So can moving your hands frequently. Seat suspension also makes a difference. If it’s too soft, your spine can be damaged if the seat hits the floor on a bad road.
