Summarize the following:
Pull your trailer onto a flat, level patch of ground. For safety, do not use slanted areas like driveways. Then, put the vehicle you used to tow the trailer in park and activate its emergency brake. For extra security, place wheel chocks in front of and behind each tire. If you’re using a trailer made specifically for towing cars, it should come with 2 heavy duty ramps. To use these ramps, simply pull them out of the vehicle’s rear body and make sure they’re parallel and secure.  If your trailer doesn’t have built-in ramps, you can purchase a metal ramp from an auto supply store and connect it yourself by following the manufacturer’s included instructions. Do not try to create a makeshift ramp. Doing so is extremely dangerous and can result in major damage to you or your vehicles. Once you’ve parked the trailer, pull your car up behind it. Make sure to line your wheels up with the trailer’s metal ramps. Do not back your car up to the trailer as towing your car with the tail end first can cause problems like whipping or swaying. Put your car in drive and slowly accelerate up the ramp and onto the trailer. As you drive, the front of the car will raise up slightly, then return back down and distribute its weight over the surface of the trailer.  Keep the steering wheel straight so you don’t drive on crooked. If you’re unsure whether or not you’re driving straight, ask a friend to help direct you. Keep driving until you’re centered on the trailer. Then, put the car in park, turn it off, and activate its parking brake. Finally, hop out of the vehicle and double check the car’s alignment.  If you’d like, ask a friend to stand off to the side of the vehicle so they can check the alignment while you’re driving it. If you have a manual car, put it in first gear, turn off the motor, and set the handbrake.
Park the trailer on flat ground. Extend the trailer’s rear ramps. Line your car up behind the trailer. Drive onto the trailer slowly. Park the car and check its placement.
