Ambulance services may be private for-profit enterprises, private non-profit entities, municipally run or volunteer services.
A commercial driver's license (CDL) allows you to operate a commercial vehicle in Virginia and possibly other states, depending on your qualifications. To obtain a CDL or commercial learner's permit (CLP) in Virginia, you must meet all requirements for a Virginia driver's license. You may hold either a driver's license or a CDL, but not both. You must apply for your CDL or CLP in person at a DMV customer service center. For additional information about CDL licensing, please refer to CDL classifications, endorsements and restrictions. Age Requirements. You must be at least at 18 to obtain an intrastate CDL and age 21 to obtain a CDL. Identification and Residency Requirements If you apply for a CDL or commercial learner's permit and DMV records show you have not held a Virginia driver's license or ID card in the past, you must present documents proving your eligibility.
