Displayed in each section of the start line, this flag signals a delayed start of the race. Displayed waving over a row of the starting line, this flag indicates that the rider in that row is having trouble. Displayed at the flag marshal position, this flag means that there is a danger ahead of the track. Two yellow flags on the marshal’s column signify that there is a risk, either ahead or partly or entirely, of blocking the track. The riders need to calm down and be prepared to stop.
Any breach of this provision during the practice session would result in the cancelation of the lap time during which the violation happened. In the case of an infringement of this law during the race, the rider must return to the place number determined by the Race Route.
Red flags, red lights
A red flag will be waved at each marshal’s position if a race or practice is interrupted, and the red light will be turned on around the track. The riders must slowly return to the hole. When the exit of the pit-lane is blocked, the flag will be permanently displayed at the exit of the pit-lane and the light will be on. Drivers are not permitted to leave the road.
If two-thirds of the race distance in Moto2 or Moto3 or three-quarters of the race distance in MotoGP (rounded to the nearest maximum number of laps) has been completed by the race leader and all riders. In the same race leader, the race will be declared completed and full points will be awarded.
There’s a race going. The red light will be on the start line for around two to five seconds to start each race. “So the lights are off” is the commentator’s preferred term to say that the race has ended, as this is a warning to the riders that the race has started. At the conclusion of each practice session and the warm-up, there will be a red light on the finish line.
