Your state’s trucking industry is struggling.

Not only is there a years-long driver shortage, the candidates who do come forward are failing the written exam at an alarming rate. In fact, over 50% of people fail their CDL knowledge test.

Then, when candidates finally pass the written exam after several tries, they are faced with the dreaded pre-trip inspection. Candidates show up overwhelmed & unprepared, giving the pre-trip inspection an even higher failure rate.

This black hole is a dangerous place for CDL candidates and leaves little hope for states to get more truck drivers on the road.
