Drag racing  is a in which vehicles compete to be the to cross a set finish line, from a standing start, and in a line. First gaining in the USA after World War II, the sport grew in popularity and spread the globe. By 2009, there hundreds of dragstrips  in operation, in developed countries.

each race (also as a pass), each driver is to perform a burnout. which the tires and lays rubber at the beginning of the track, improving Each driver then up (or stages) at the starting line. drag races can be started by any including flag-waving and arm-dropping.

methods are more likely to be in an unorganized setting, being popular with illegal racing. Sanctioned races are electronically, with a series of lights known as a Christmas or just tree. The Christmas consists of a column of lights for driver/lane. In each column, the top two are small amber lights to light beams on the track, when broken by the vehicle’s tire(s) indicate that the has pre-staged (approximately 7 inches mm) from the starting line) and staged (at the starting line). [ 2 ]

Below the staging lights are large amber lights, a light, and a red light. When drivers are staged, the tree is to start the race, which the three large amber to illuminate, followed by the green There are two standard light either the three amber flash simultaneously, followed .4 later by the green light (a Pro or the ambers light in sequence top to bottom.

5 seconds apart, followed .5 later by the green light (a tree, or full tree). If the breaks the starting line before the green light the red light for that driver’s illuminates instead, indicating (unless a more serious occurs).

Some cars on traction bars  to prevent the from twisting the axles heavy acceleration, [ 3 ]  transferring the onto the whole body. some cars rely bars  to keep the front end lifting off the pavement and wasting that would otherwise the car forward. On front-wheel-drive cars, are used not to prevent wheelstanding, but to more weight onto the wheels, increasing traction.

measurements are taken for each reaction time, elapsed and speed. Reaction time is the from the green light to the vehicle leaving the starting Elapsed time is the time the vehicle leaving the starting to crossing the finish line.

Speed is measured through trap  near the finish indicating the approximate maximum of the vehicle during the run. Top Dragsters and Funny Cars are now 310 mph (500 km/h) in a [1,000-foot (300 m)] race.

The is the first vehicle to cross the line (and therefore the with the lowest total time + elapsed time) breaking out (going faster a dial-in) or redlighting. The elapsed is a measure of performance only; it not,  per se . determine the winner. elapsed time does not reaction time, a car with a elapsed time can actually

In practice, it is advantageous for the driver to the car during the split-second interval when the yellow light out and the green light goes on. a driver commits a red-light the other driver can also a foul start by leaving the too early but still win, left later. A driver who a substantial lead at the start is to have gotten a holeshot.

A win where a driver wins a with a higher elapsed but lower reaction time is as a holeshot win.

It is also for a driver to be disqualified for other depending on the rules of the race, crossing the centerline between touching a wall, striking a fixture, failing to stage, a tech inspection, or running than expected/allowed for the assigned In boundary line violations, if the driver has made a clean and the red-light driver does not the violation unless forced by the car for safety reasons, the driver who a red-light foul wins.

In the common Eliminator racing the losing vehicle and driver are from the contest, while the goes on to race other until only one is left. In where a driver has no opponent for a the driver makes a solo or bye run (in order to at least partially the advantage that would come from the engine one less run on it) to advance to the next In most Eliminator formats, the bye take place only in the round.

On bye runs, some may choose to drive slowly so as not to the car unduly, though choice of in the each round is often by time in the previous round, this strategy possibly Unlike the NHRA, many events feature a consolation where the losers of the semifinal race for third place, the spot on the podium, and standings

During drag racing vehicles are classified by various that take into the extent of modifications to the car. criteria include engine configuration of cylinders, frame vehicle construction materials, horsepower (or displacement) to weight number of cylinders, whether or not adding equipment (turbocharger or nitrous oxide ) is employed, type (such as car, or motorcycle), or even make and for limited entry fields. The divisions are in place to ensure are evenly matched during the Not all of these apply at once.)
