Before each race (also known as a pass), each driver is allowed to perform a burnout, which heats the driving tires and lays rubber down at the beginning of the track, improving traction. Each driver then lines up (or stages) at the starting line. Races are started electronically by a system known as a Christmas tree. The Christmas tree consists of a column of lights for each driver/lane, one blue, then three amber, one green, and one red, connected to light beams on the track. The first, a split blue open circle, is split into two halves. When the first light beam is broken by the vehicle's front tire(s) indicate that the driver has pre-staged (approximately 7 inches (180 mm) from the starting line), lights the first half of the blue circle, and then staged (at the starting line), which lights up the second half of the blue circle, and also the corresponding bar in the middle of that circle.
