Human: How can I tell if my car is being towed? Assistant: 
Tell if Your Car Is Being Towed
1.  Listen for the sound of a tow truck engine and see if you hear it coming up behind you.
2.  Look out your rear window and try to spot the tow truck's flashing lights or other warning signs.
3.  If you're in traffic, look for police cars that are following the tow truck.
