Dissecting the dragstrip
While at first glance drag racing may seem like a fairly uncomplicated sport, it does have it's fair share of insider info and jargon. When you’re at the track, you wanna know more than where the grandstand, the food and the dunnies are? For all the novices and those that all too easily forget, here’s whats where and what does what...

Burnout Area
Commonly there are small depressions in the track surface just before the starting line. These are designated for vehicles to do burnouts and are sprayed down with water before a vehicle enters. The driver pulls up until the rear tyres are just at the edge of the water and then does a burnout to warm up the tyres and get rid of any foreign objects lodged in the tread.

The Tree
Located just forward of the start line. The tree (commonly known as the Christmas Tree) is the set of vertical lights that let the driver know when it is time to race.

60-Foot Timer
When you hear the commentator talk about the 60-foot time, you’ll now know that he means the time that it takes the car to go from the start line past an optical trigger that measures the time. This time gives an indication of how well a car is launching. Usually a quick street car will record around two seconds, while purpose-built drag cars such as Rotormaster’s have recorded times as low as 1.2 seconds.

660-Foot Timer
As a 1/4-mile track is 1320 feet, the 660 mark is exactly half way down the track and has a sensor to measure your 1/2 track or 1/8th mile ET. Some tracks also have timers at 330 and 1000-foot intervals.

Mile Per Hour Timer (terminal speed indicator)
Usually known as the speed trap, the terminal speed indicator is located 66 feet before the finish line and records the car’s average speed between it and the finish line. The result is normally found at the bottom of the time slip listed as MPH.

Finish Line
When a vehicle crosses the beam at the end of the quarter-mile, the ET clock is stopped. The ET on the time slip is the time it takes from when the vehicle leaves the start line to when it crosses the finish line beam.

Shutdown Area
After the finish line is the shutdown area. This area is often another 1/4 mile (or more) in length and is allocated for vehicles to slow down safely before they head to the return road to pick up their time slip.
