Before hitting the road with your car trailer, make sure it's attached properly to your towing vehicle and that the brake lights and turn signals are working. Ensure that the car on the trailer is secured and won't move around. Towing anything, especially car trailers (because of their weight), requires skill and a little practice. You should drive at about half of your normal speed and provide plenty of room to brake. You'll have to make wide turns at every intersection to ensure your trailer does not cut into the other lane or hit obstacles.
