Simply, by offering challenges, not rewards you will most likely attract truck drivers who drive with ambition, not the ones that are looking forward to easy tasks.
Once you effectively write a great truck driver job ad you will be in the position where the response from the candidates will be boosted in a quality manner!
Also, if you have already any experience with writing a great truck driver job ad, please feel free to share it with us in the comment box (altogether with the results it brought to the trucking company).
So good luck with your hiring process!
