Can I park to rest for 6 hours? Thanks

I don't believe there is a time limit. A lot of truckers sleep there overnight so I don't see an issue

You can sleep there. You cant live there though! Lol

I've done it many times

Yes. There's no time limit unless you abandon the car lol

Yes

Officially, you're not allowed to park for longer than three hours. However, I've never seen that rule enforced.

There are no postings that would stop this.

Yes you can its open 24 hours and 3 miles south is a Dixie truck stop its also open 24 hours
