TORONTO — IndyCar will debut standing starts this weekend for the first race of the Toronto doubleheader.
Standings starts will also be used for the first race of the Houston doubleheader in October. Series officials spent time in the Friday morning meeting with team managers going over the start procedures.
_COUNTDOWN: The safety car will lead the formation lap and drivers will follow single-file in starting order.
_FORMATION LAP: During the formation lap, drivers will remain in starting order with no overtaking. The speed of the formation lap will be set by the safety car.
_GRID: At the end of the formation lap, drivers will take their starting positions with the front wheels of the car remaining within its designated orange grid line.
A five-second declaration will be made via radio by the race director prior to the start of the light sequence. The starting sequence will begin when the first two rows of red lights on the lighting panel illuminate. The red lights will continue to fill from the bottom of the light panel two rows at a time, for a total of 12 rows.
Once the panel is filled with red lights, there will be a delay between 0.5 and 3 seconds and the panel will switch to all green lights and the race will begin.
_FALSE START: A false start shall be declared when a car moves forward or is out of its assigned position before completion of the light sequence. A penalty will be imposed for a false start.
_ABORTED START: The race director can declare an aborted start before the final row of red lights is illuminated on the lighting panel. If the start is aborted, the full-course caution lights will be turned on.
In the event of an aborted start, a rolling start will be implemented. Any competitors whose actions result in an aborted start will move to the rear of the field.
IndyCar required teams to practice at least one standing start during Friday morning's practice session. There was a practice box at the exit of pit road with the lights system manned by an IndyCar official.
