How can i obtain a nascar racing liscense[Camping world truck series]?

Hi, how do you obtain a racing liscense for the NASCAR Camping world truck series?I cant find any information on the internet and want to know what the cost is and if i have to get a series of liscenses?any info or site recommendations would be appreciated.|||You need a "National Touring Series License", with an endorsement for tracks of two, and a half miles, or more.. The same license you need in Cup, or Nationwide.. You need to work your way through a couple of other licenses to get there..
