Wannabe about ready to go big time!

I am a wannabe about to attend trucking and Heavy equipment operator school in LA at College of Instrument Technology in Bellflower. I have recieved funding for the $8K school and will not have to pay back a dime due to funding and being laidoff from my last job and Veteran status. After the 2 & 1/2 month program I will have class A CDL, OSHA Certifications, Forklift, Backhoe & Forklift Certified, Tie down certified, & Hazmat testing and spill cleanup, OSHA Confined space. The program is 240 hours minimum. My question is "Will I be experienced enough with this school Certifications to Jump right into a Long Haul Cross country driving job straight out of school?" I want to drive routes up and down west coast to Alaska from Los Angeles and also Los Angeles to Dallas where I have family. Do you think this will be a quick possibilty? I appreciate any info you may have for me. I am 48 and looking forward to making this my career for the remainder of my working life if I don't move into management with a trucking company before retirement age. Any opinions or advice? Thanks Much Wannabe about to go big time!
