Nothing prevents someone from suing you.
Them winning, is dependent on the facts of their case against you.
An example - you own a pool, you have a no diving sign, you allow the water to become murky, someone dives in and busts their head, you might be liable because they couldn’t judge the depth due to poor water clarity.
Or, you own property, crossing your property is the closest way to get to the river, there are well worn tire tracks from many people using the shortcut across your property, you know this and don’t put up a fence or other method of blocking the traffic. You’re out shooting one day on your property and hit someone taking the shortcut. You might be liable.
Or, you own an apartment building, you have signs in the parking lot that say ‘property under surveillance’ you have a camera but it is not monitored, an occupant of your complex is mugged in the parking lot, you gave them a false sense of security, you might be liable.
Reasonable care needs to be used in most cases
