Towing hook edit
Towing hook (also known as tow loop, bar, eye, hitch, bracket, ring) is a device attached to the chassis of a vehicle for towing, or a towbar to an aircraft nose gear, or paired main gears. Almost all cars have front and rear towing loops (unfortunately, some American models don’t have welded or screw hooks). In older cars they are visible under the bumper, while in newer vehicles, they are recessed and covered with a plastic lid in order to camouflage them with the vehicle's body. This also avoids additional aerodynamic drag, and noise.
Welding towing hooks edit
Towing hooks are welded to the cars body elements, but stitches, especially if they are corroded, sometimes can fail to hold the hitch in place when starting to move. Screw loops are similar. For some cars, towing hooks were designed like for a gentle level ground towing. Any stronger twitch on higher angle, can bent or even break the hook. One of the reasons why loops where produced with weak structure, is that it would be hard to break the car's body geometry. So in this case, designers would prefer the hook to bend, because it is inexpensive and easily replaced.
Notice! edit
Snap cables are not designed to be attached to any other car parts. Doing so, could damage the chassis geometry or even tear off the bottom of the bumper.
Advice edit
For a successful tow, that doesn't result in reparing both vehicles, experienced drivers advise that both parties should agree on car signals to use during the towed journey. For example: The driver in the lead car can briefly press the brake pedal lightly to "flash" the brake lights to warn of imminent braking. If the driver in the towed vehicle would like to stop, they could similarly push their break a few times gently. Alternatively, other signals like lights flashing, indicators, light beeps of the horn could be employed to allow basic communication for the towed journey. A higher tech approach would involve both drivers establishing a hands-free mobile call to keep in verbal contact.
