I have a friend without a driver’s license but he wants to buy a car but is that legal in Illinois?. What’s The Illinois Law For Buying A Vehicle Without A Driver’s License?. I couldn’t wait until I turned sixteen so I could get my driver’s license. Of course, you can’t get behind the wheel of a car without one. So my question is, can you buy a vehicle when you don’t have a license? That’s an interesting question and I found the answer.
