Wish I knew more about crude oil transport. I did look up some information. From what I see this type of job pays more like $50,000 per year. One company that has Crude oil Transport jobs in Texas available is Sentinal Transportation. copy this web address nd paste it in the window to go to their employment page. http://www.sentineltrans.com/employment/
I am pretty sure you will need some truck driving experience first before they let you haul crude oil though. Hopefully someone familiar with crude oil transport will come on the site and respond with a more insight reply.
Meanwhile copy the text after this paragraph and put it in the search box on the ask a trucker page to get the search results for other crude oil transporter jobs. Give them a call and ask them about requirements.
