It varied from state to state. I live in Maryland, and there was maybe a 2 week period last spring where you weren't allowed to drive anywhere except to get groceries and medicine, or if you were an essential employee for a business that was allowed to stay open. Outside of that two week period, the only travel restriction I know of was a mandatory quarantine period for people traveling in from other states.

Ah, for comparison we had a 6-week period of similar restrictions last spring. Followed by another 4-week period in September, and a 3 month period at the start of this year.

Outside of those times there were restrictions on meeting indoors (at times max 6 people, at other no meeting indoors at all) pretty much continuously since last April.

I think most of the US had much less strict "lockdowns". I think the most restrictive it ever got in my area was that gatherings of 10 or more people were not allowed, and to actually get it enforced, you probably had to go way over 10.

Also, in the USA there were a lot of things that were on paper "not allowed" but it didn't matter because it wasn't enforced at all. Mask wearing, social distancing, stay-at-home orders, did people actually get cited for violating? I know, at the height of the pandemic, I could easily drive out of my region, eat at a restaurant indoors, gather somewhere unmasked, and there was zero chance I'd be fined. Even for things like mass-gatherings, usually it was just the business owner who got fined, and the 1,000 people caught gathering got off scott free.

I remember a period last spring and early summer when parties and gatherings were getting "busted", but I don't think the enforcement of restrictions on private gatherings has been meaningful for the majority of the pandemic.
