At a roadracing event, a member of the officiating crew (or trackday organizer'
s staff) who watches the exit of corners for motorcycle (or other vehicle) crashes.
Generally, cornerworkers hold flags to regulate the racetrack - red, black, blue, yellow,
green, checkered, and meatball flags - and are equipped with
fire-extinguishers and radios, and a strange will to stand in the hot
sun all day while people crash all around them at over 150 MPH.
"I'd like to
thank my sponsors, the race officials, and the
corner workers for allowing us to race here
today..."
