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..."
