Since you're actually asking(maybe?)

In the US, and I think Canada, but also other countries have equivalent systems, we have non-commercial driver's licenses and commercial driver's licenses (CDL, you often see).

Non-commercial is your normal person license to drive normal sized, relatively light vehicles legally. Usually it's denoted on your license as Class C. Class M is for motorcycle typically. You can also hold non-commercial Class A and B, but those are less common, typically found with retired drivers only.

Class A CDL is the big trucks over 26,001lbs (from memory, been years, might be wrong). There's some length limit too and people can google that if they care because, like I said, it's been years

Class B CDL is big, heavy vehicles but not the big rigs. Typically busses, although some trucks can qualify. I think cement trucks is an example from memory. Heavy trucks that aren't towing a lot.

Class C is for like normal sized vehicles that have passengers. I believe school vans are in this group as an example.

There's also endorsements (that's what they're called) that are required to drive certain vehicles. For example, air brakes, that all the big tractor trailers have, is a requirement along with a class A CDL to legally operate a tractor trailer. The person's license gets additional letters (depending on the state but it's pretty uniform now days). Like in PA I think, from memory, air brakes is indicated with the letter L under endorsements. There's a bunch of others like H for hazardous materials handling. P for passengers is what the OP got and probably one or two others (they test them all simultaneously or consecutively usually. Just one big test)

If you have a US license you can see your own endorsements and restrictions (like medical devices required. Glasses being the most common). For most drivers there will be no endorsements and probably no restrictions either besides glasses. Some people can get restrictions like they need special mirrors to drive safely and stuff like that. I only ever saw glasses and some restrictions specific to CDLs (like the drivers not being allowed to drive manual transmission tractors- only automatic. This is caused if they tested in an automatic. Makes sense)
