Is it legal to tow dolly a car backwards?

yes you can dolly a car backwards but you should follow these guides. 1) The car has a steering lock and it is engaged. 2) There is no one in the vehicle whilst being towed. 3) You have a towing light bar so that people can tell the vehicle is going backwards. 4) The handbrake is on if it is a manual vehicle. 5) The drive selector is in "N" for automatic vehicles This should be a good rule of thumb no matter what type of vehicle you are towing.
