A "normal" license is an Operator License. That is, with an Operator License, you can drive all the normal cars that you would normally drive out of your friendly Toyota dealer's show lot.* 

With that Operator License, you can also drive pretty much any vehicle that's less than 26,000 pounds, as long as you're not transporting hazardous materials or towing a trailer with a gross weight of over 10,000 pounds. You also can't drive a bus if it's designed to transport more than 15 people including the driver. 

So, what types of driving does that cover?

• A recreational vehicle that is less than 26,000 pounds
• A giant van or mini bus that seats between 10 and 15 people
• Mopeds
• A golf ball
• Your parents crazy

Note that farmers and drivers of authorized emergency vehicles who are exempt from obtaining a commercial driver's license are still required to obtain a Operator license.

Also, you're allowed to tow another vehicle, but you can't tow more than one vehicle at a time. That's just nonsensical.

Other License Classes

So, the Operator License is the biggie. It's the license most people have. But there are a ton of that you can get. Check 'em out on Michigan's Secretary of State website.

• Commercial Class A (CDL-A)
• Commercial Class B (CDL-B)
• Commercial Class C (CDL-C)
• Chauffeur—If you want to drive a bus, taxi, or limousine, and get paid for it, which is kinda the point, then you're going to need a Chauffeur license.
• Motorcycle Endorsement
