Towing On Motorway

I bought a car and it needs towing house, am I aloud to tow on a highway with a tow bar (no rope)

Yes.
Make sure, however, that the lights are working on two vehicles, the registration number of the towing vehicle is clearly marked on the vehicle towed, a "yellow light" warning lights are NOT used and the speed limit MSP 60 is observed. It would be preferable to use a Larger Size / semi-trailer and roads instead of a highway is preferred.

OK as you have a game board tail lights with license plate on her car first.

No, you can exit a highway towing is not on it, you need a recovery of some sort of vehicle with at least the front wheels resting on the ground
