Will a sr22 bond stop you from getting a cdl license?

Getting a CDL won't be so much of a problem... finding employment as a CDL driver, on the other hand, is going to be. Basically, if you have more than three points on your license within the previous three years, they're not going to want you. Depending on what you're on an SR22 for, they may expect an even longer time period before they'll even consider you.
I'd recommend you call some prospective employers and see what they tell you before you commit to the expense of a CDL program, especially if you're expecting post-employment reimbursement of that expense.
