Driving HGV in Los Angeles

Wg2:
So I’m HGV class one driver in the UK, i’m looking to migrate to Los Angeles because of my wife.

Just a question for example I do understand I have to pass a test in the USA to drive HGV Lorry’s. However do need to pass a car test first ? As I think a UK car license can work in the USA not sure.

Thats the cheapest way to get into it i know. but other will know different ways.
