Thompson Trucking has been using the services of NTA for many years. There customer service is beyond measure. I can call at a moments notice and get immediate assistance. There services as an MRO for drug testing is excellent. I have my reconciled list sent each quarter exactly on time. NTA has the staff and knowledge to answer any issue that may come up. If audited, they are able to provide ALL necessary documents to produce to DOT. I strongly recommend NTA
