Just that frequency at that location.
The only problem you can run into is if a LEO is at that location on the same frequency or very close to that frequency.
There was one video where a leo was locked out on the freeway when vortex was testing and he couldn’t figure out how that happened.
Lockouts aren’t perfect. Some LEOs will sit under a k source to mask their presence.
Still need to be aware of your surroundings.
