A quick 180 degree moving turn in a car. With skill it can be done on a two-lane road. Bootlegger turns are easiest if done with an automatic transmission and a hand emergency brake. Make sure the tires are fully inflated, and realize you'll be scraping a fair amount of tire life away - a rental car is a good way to practice this. If you have hubcaps, they probably won't stay on. Preparations aside, the actual steps are fairly easy.

1. Keep the car straight and at around 30-40 mph
2. Taking your foot off the gas pedal, start frantically turning the steering wheel for about a quarter to a half of a complete turn while using the emergency brake hard. (Manual transmission drivers: Depress the clutch at the same time.)
3. When the car rotates about 90 degrees, release the emergency brake, hit the gas and then turn the remainder of the way. (Manual drivers: Let the clutch out as you take off)

The turn was originally perfected by moonshiners fleeing liquor revenue agents, hence the name "bootlegger turn." It's perfect for evading pursuit or escaping from roadblocks. It's possible to do this in reverse. This is called a moonshiner turn, and the steps are essentially the same.

It is worth noting that in front-wheel-drive cars, one doesn't even need to come off the gas pedal (or on the clutch) to perform this manouver, although it can be a good idea, to minimise the likelihood of understeer.

In all cases (no matter which wheels are driven), in a manual car, make sure to change down to first gear just before you yank the handbrake. If you do not it is very likely you will stall the car. If you jump back on the gas just before you finish turning (in a RWD car) you'll exit the turn with your wheels spinning in a very stylish manner indeed, and get moving again as fast as possible. This is a real crowd-pleaser at motorkhanas.

Also worth noting is that this WILL NOT WORK if your car has a handbrake that operates on the front wheels. If attempted, you will go into a massive understeer slide, and NOT look 'all cool like the Dukes of Hazzard'.
