There are no age restrictions for owner-operators. But there are a few things you need to consider before diving in. You should be at least 21 years old and have a clean driving record, according to the FMCSA. It also requires that you have at least one year of experience if you’re going to drive with an interstate license. You can get this by driving as an employee or as an independent contractor. The FMCSA also requires 60 days of driving experience with your state’s intrastate license before applying for an interstate license.
