Loading a car onto a proper trailer will be perfectly fine, as the vehicle wouldn't even be on the road. There is no law against towing on the motorway as long as it is done safely and within the 60 mph speed limit for cars and trailers. Just remember, you are not permitted to use the right-hand lane at any time, unless instructed to do so by overhead matrix signs, or passing a wide load which has an escort vehicle. Remember to obey your vehicle's towing weight restrictions, and what your driving license permits you to drive, as trailers over a certain weight require a different class.
