Violator Towing

[packerr]

In some no-parking zones, the signs read:

"Violator Will Be Towed At Owner's Expense"

Does 'violator' refer to the illegally parked vehicle, or the vehicle owner? Most dictionaries claim that a violator must be a human. Yet, a human violator is normally not towed, because it would kill that human. So, could the signs be poorly written?

You understand that the car will be towed.

"Violators of the law will have their vehicles towed at owner's expense" is long sign.
