1499:. A driver may be black-flagged for failing to maintain a reasonable minimum speed, even if no apparent damage or mechanical failure is present. In almost all cases, the team is given a chance to make repairs to the car and get it up to an acceptable condition. If the driver still cannot maintain minimum speed in relation to the leaders after repairs, the driver may be required to park for the remainder of the race. For example, NASCAR requires that a driver run at or above 115 percent of the fastest lap time by any driver in the final practice. (This can be converted to an average speed-limit based on the length of the course, which for oval tracks will be close to the actual speed limit at any given time.) IndyCar has a 105 percent rule, most notably used when officials parked

This practice, while giving lapped drivers a better chance to make their lap back, was at times highly dangerous in that it encouraged drivers to engage in pitched battles with major safety hazards on track. Safety workers were not able to respond to accidents until the cars were under control of the pace car, which markedly slowed their response times to potentially injured drivers. To compensate for the elimination of the race back to the caution, NASCAR and some other motorsports series, both road racing and short oval, have implemented the

As such, it is often referred to as the "courtesy flag". In other series, drivers get severely penalized for not yielding or for interfering with the leaders, including getting sent to the pits for the rest of the race. In

Supercars, a race that is suspended after 75% of the laps have been completed may be declared complete at the race director's discretion, such as happened in Supercars forerunner

Twin yellow flags displayed at the starter's stand indicates a "full-course caution", in which the pace car would enter the track and the entire course would be under caution.
