A blue flag with a diagonal yellow stripe tells the driver a faster car is about to pass, and the driver must yield to the faster car. A white flag indicates the race leader has one lap to go. A checkered flag means the driver has crossed the finish line and won. The best way is to stay tuned to your scanner, or keep an eye on the electronic scoring pylons in the infield. After an accident, drivers unhook their window nets to signal they aren't hurt badly.
Most drivers walk away relatively unhurt, thanks to rigid safety standards.
