Cornerworker Roles and Duties
Each cornerworking team is made up of people filling various roles. Each corner crew should have a Captain, Radio Communicator, Primary Flagger, Back-up Flagger, and one or more Pick-up people. Some of these jobs may be combined as necessary.
  • Corner Captain - The person responsible for the operation of the corner. Ensures correct placement of equipment and workers; trains inexperienced workers; oversees the safety of workers, competitors, and spectators in the corner.
  • Radio Communicator - Keeps the Captain and Control aware of changes in track conditions and calls for assistance when required. Carries and displays the red flag as appropriate. In the absence of a specific person to serve as the Communicator, the Captain will assume this role.
  • Flaggers - The flaggers serve as the competitors' eyes, warning riders of hazardous situations by displaying signal flags.
  • Pick-Up - The pick-up person is stationed in impact areas, generally downstream of the flagging position. Primary responsibilities are to help maintain a clear course, assist fallen riders, and move machines to safe positions.

Cornerworker Priorities
When cornerworking, no matter what job you are performing, you should always keep in mind these five cornerworker priorities.
  1. Your own safety
  2. Your fellow workers' safety
  3. The safety of riders still racing
  4. The riders involved in the accident
  5. Removal of vehicles and debris from the track

Do's and Don'ts
  • Enjoy yourself.
  • Introduce yourself and get to know fellow workers.
  • Motion to off-track racers when it's safe to re-enter.
  • Keep spectators behind fences; report offenders to Control.
  • Dress adequately.
  • Drink lots of water and juice.
  • Have flags, fire bottles, radios, and oil clean-up materials ready.
  • Give the name of an injured rider to the Corner Captain.
  • Always use gloves when touching a fallen bike or debris.
  • DON'T
  • Turn your back on traffic.
  • Move a fallen rider who cannot move him- or herself.
  • Remove a racer's helmet.
  • Cross a bike across a hot track.
  • Offer an injured rider food or drink.
  • Wear yellow or red clothing.
  • Drink alcohol or take drugs.
  • Leave your station to push a bike back to the pits - stay on station!
  • Pick up hot parts - kick them off the track instead.
  • Cross the track without the Captain's permission.

  • Flagging Procedures
    Two flaggers are positioned on each station; one is the primary flagger, the other is the backup flagger. When an incident occurs, flaggers immediately display the appropriate flags. Changes in flag conditions may be requested by other cornerworkers if necessary.

    The primary flagger holds the yellow flag and watches downstream (race direction). When an incident occurs, the flagger turns to face oncoming traffic, signaling as appropriate. When the incident is over, the primary flagger returns to watching downstream.

    The back-up flagger's main responsibility is to protect the Primary flagger by watching upstream at oncoming traffic. The back-up flagger holds the debris flag and displays other flags as necessary. When the primary flagger turns to display a flag, the back-up flagger will move to a position where they may observe downstream, while maintaining verbal contact with the primary flagger.

    The flagger's area of responsibility is from their flag position to the next downstream (race direction) flag station. Flaggers must remain at the flag station at all times while the competitors are on course. However, personal safety is paramount; in case of an out-of-control vehicle, avoidance may be necessary. Once established, a flag location does not move for the duration of the race day.

    Flag Descriptions & Meanings
    Solid yellow flag Stationary Yellow - Indicates a potentially hazardous condition on or near the track, or a slow moving motorcycle. Passing is allowed. The yellow flag is displayed in a stationary manner whenever the incident of off the racing surface.
    Solid yellow flag Waving Yellow - Flag is waved vigorously in a figure-8 motion to indicate a hazard on track of a serious nature which may require avoidance maneuvers. No passing is allowed from the flag station displaying the waving yellow until the rider is beyond the incident. The yellow flag is waved whenever the incident on the racing surface. Waving on the Paving - Steady on the Grass
    Yellow with red stripes Stationary Debris - Debris or a potentially hazardous condition on the track surface. Passing is allowed.
    Green with vertical black stripes Stationary Pickle - (WERA Only) Indicates a slippery racing surface.
    Yellow with red stripes folded Debris (Rain)- Debris flag is folded in a triangle with the red stripes up and down, facing the rider, to indicate falling rain. Informational only, passing is allowed.
    Yellow with red stripes "Debris Point" - Debris flag is shown to an oncoming rider, then furled and pointed directly at the rider to indicate the bike or rider has a hazardous condition (such as smoking, leaking, loose part, unzipped leathers, etc). Typically, riders will receive a black flag at start-finish as well.
    White with red cross Ambulance - Indicates that ambulances, safety, or emergency vehicles are on course.
    For CCS/ASRA:
     Display the stationary ambulance flag at all flag stations around the course and at the Start/Finish.
     Display a waving yellow flag and a stationary ambulance flag at the flag station in which the emergency vehicle is located, moving or parked.
     Display a stationary yellow flag one flag station immediately preceding the emergency vehicle’s location, in addition to a stationary ambulance flag.
     A waving yellow flag and stationary ambulance flag should accompany the emergency vehicle through each flag station around the racetrack, with procedures described above, until the vehicle returns to the paddock area.
    For WERA:
     Display standing at all stations with waving ambulance at the location of the emergency vehicle.
    Solid red Waving Red - Indicates the session has been stopped; riders should reduce speed and proceed safely to pit road. No passing is allowed under red Flag conditions. ONLY Control calls for a red flag – captains request a stoppage.

    Hand Signals
    • Standing Yellow - Hold one arm out to side to indicate a potentially hazardous situation on or near the track.
    • Waving Yellow - Move one arm up and down to your side to indicate a hazardous situation on the track.
    • Standing Debris - Form the letter "O" with your arms to one side to indicate solid debris on the track.
    • Rocking Debris - Move your hand out to one side as if wiping the ground to indicate that there is something slippery on the track.
    • Stop The Session - Move both arms up and down at your side as if signaling two waving yellows to request that the session be stopped.
    • Ambulance - Hold both arms above your head, forming the letter "A" to indicate you need an ambulance.
    • Severe Injury - Signal for an ambulance, followed by pounding on your chest to indicate serious injury.
    • Fire - Hold arms to one side, forming the letter "F" to indicate you have a fire and need fire bottles.
    • Crash Truck - To request a crash truck to return a disabled motorcycle to the pit/paddock, motion as if pulling a rope toward your body.
    • Safe - Use the baseball "safe" signal to indicate a competitor is OK or to cancel a flag request.
    • Re-enter - Rotate one arm above your head to signal that a rider will re-enter the track.
    • I Need Help - Tap on your head to indicate you need assistance.

    Hand signals are also used to communicate competitor numbers. To ask "what number?" form a "W" with your arms over your head and then cross your arms over your chest.
    • Pump arm towards the sky the number of times equal to the number you are communicating - the number five would be 5 pumps upward like punching the sky.
    • Change arms for next number and continue
    • Signal a zero by a wiping motion from the shoulder towards the wrist.

    Signaling to Riders
    A worker stationed upstream of an incident should signal, using an exaggerated pushing motion, to direct a competitor to a particular side of the track for avoidance of debris or other obstacles. Turn your body to indicate the direction. Never use a pulling motion.

    Dealing With Injured Riders
    Cornerworkers do not provide medical services to injured riders; the raceway is staffed by professionals to attend to medical emergencies. However, since cornerworkers are first on the scene of an incident, there are certain things we should do until medical crews arrive.

    The main points to remember are:
    • Keep rider calm and safe
    • Keep talking to the rider, even if apparently unconscious
    • Always look upstream; if one rider crashed there, another may soon follow!
    • NEVER remove a helmet!
    • Never give a rider an assessment of physical injury or damage to the motorcycle; be reassuring and positive
    • If a rider is combative, get help
    An injured rider is referred to as either UP (walking around) or DOWN (on the ground). There are some differences in how to deal with each type of injured rider.

    Up Rider
    A rider who has gotten up after a crash may be injured but may not realize it. The following procedures will help you assess the rider's condition.
    • As you approach the rider, look for any signs of injury
    • Talk to the rider; ask their name and where it hurts
    • Guide the rider to a safe location, out of the impact zone
    • Stay with the rider
    • Keep talking to the rider as a tool for assessing their condition
    • Check for signs that would indicate a hidden injury: damage to the helmet or leathers; obvious deformity of legs or arms; limping; heavy bleeding; incoherence.
    • If the rider is OK but will not re-enter the event, make him safe and comfortable - put the rider away from the track in the shade and offer some liquids.
    • If you are concerned about the rider's condition, request an ambulance.

    Down Rider
    • Assess severity of rider's injury: not breathing? bleeding profusely? unconscious?
    • Signal for an ambulance to be called
    • Protect the rider with haybales or tires if necessary
    • If the rider is in a location that makes it too dangerous for the session to continue, ask that the session be stopped
    • Keep talking, even if the rider seems unconscious
    • Shield the rider’s face form the sun with a flag
    • Don't move the rider; keep still
    • Stay with the rider
    • Don't give food or drink if injured.
    • Lift the face shield to make the rider more comfortable.
    • NEVER remove a helmet!

    Bike Pickup and Inspection
    Each corner crew includes at least one pick-up person. This person is stationed near an impact area, watching upstream, ready to respond to an incident and assist the racers.

    Any person stationed as pick-up should wear gloves at all times. Gloves are necessary to prevent cuts and burns when picking up a crashed motorcycle. If you're not wearing them before an incident occurs, there won't be time to put them on.

    Generally, the pick-up person will be the first worker at the scene. They will survey the scene and assess the condition of the rider, the motorcycle, and the track. At any time a pick-up person's responsibilities may include the following:

    • Assessing a rider's condition
    • Signaling the captain for an ambulance
    • Signaling the captain if there is debris on the track so the proper flag is displayed
    • Escorting a rider to a safe location
    • Moving a disabled bike to a safe location
    • Cleaning the track
    • Signaling a competitor when it is safe to re-enter the track
    • Examining both rider and machine to ensure that they are safe to continue after a crash

    Checking a Crashed Bike
    Many times, a competitor who has just crashed will not notice the dangling brake lever or leaking crankcase. Before the competitor can re-enter a session, the pick-up person should STROBE the bike and rider:

    S Steering: damper, forks, handlebars in working condition?
    T Tires: Flat, jammed, or wheels damaged?
    R Rider: Fit to continue (coherent, mobile, no apparent injury)?
    O Oil: Any fluid leaks?
    B Brakes: Brake and clutch levers functional?
    E Engine: Cracked or leaking?

    Cleanup of Bikes, Debris and Oil Spills

    A crashed bike that remains in an impact zone is a hazard to other riders and should be moved. Ideally, a bike will be moved to a location that allows it to be picked up by either the rider's pit crew or the MARRC pick-up truck while the session is still underway. If this is not feasible, it should be moved to the safest location possible. In certain locations, a bike in an impact zone may be covered with tires and removed after the session is over.

    Solid Debris
    Any physical debris should be removed from the track as soon as safely possible.

    • Wear gloves
    • Don't cross track without captain's permission
    • Use extreme caution when on the track removing debris
    Oil Cleanup
    The MARRC Safety Crew uses three materials for cleaning up oil on the track:
    • Kitty Litter - A dry, granular material similar to its commercial namesake. Also called oil-dry.
    • Fluffy Stuff - A loose, fibrous material (Fiber Pearl), similar in consistency to attic insulation.
    • Diapers - White, fibrous cloth that absorbs oil but not water.
    These materials are generally used as outlined below:

    Material How to Use Use For Don't Use For
    Kitty Litter Scuff in, sweep or blow off Extensive spill or windy conditions Wet conditions
    Fluffy Stuff Scuff in, sweep or blow off Small spill or wet conditions Windy conditions
    Diaper Blot area and remove Puddle of oil Other fluids

    Radio Procedures
    Communications on the MARRC network are through hand-held FM radios. Because it is an FM network, only one person can talk at a time. The MARRC Safety Crew frequency can be heard on 461.1375 MHz. Any commercially available scanner can pick up this frequency. We recommend to anyone interested in learning our procedures, or who wants to hear what is going on around the racetrack, to purchase a scanner and monitor the MARRC network.

    General Guidelines
    Handle all radios and scanners with care. Radio equipment accounts for a huge part of our operating expenses. Keep radio equipment dry at all times. Monitor the radio network at all times. Listen before speaking to ensure that you do not interrupt another transmission in progress. Always seek permission from Control to enter the radio network. Identify your station location and the flag condition of the corner. Talk in a normal voice, giving complete details in one short communication. NEVER USE THE WORD "RED" ON THE RADIO! Use "crimson" instead.

    Routine (Non-Emergency) Calls
    There are typically two types of routine calls: reports of a minor incident, such as a runoff ("moto") after the fact, and reports of a non-emergency incident that is underway.

    In any routine call, wait until the network is free. First, state your station number and flag condition. Wait for Control to acknowledge you, then proceed with your report.
    • Report numbers using single digits (e.g., "one-zero", not "ten").
    • Indicate location using the terms "rider's left" or "rider's right".
    • Indicate rider's condition using the terms "rider up" or "rider down".
    • Give additional information as necessary.
    An example of a routine call follows:
      Station 1:  Control, this is Station 1 green.
      Control:  Go ahead, 1 green.
      Station 1:  We had bike one-five down rider's right, rider is up and OK. The bike is at the pump house, please send a pick up.
      Control:  Thank you, 1, we'll send junior.
    Back-up Calls
    Back-up calls can be made directly between stations when assistance is needed quickly, without going through Control. This type of call is used when one station needs help from another, such as moving a disabled motorcycle, or when one station needs a warning flag to be displayed at the previous station. The station receiving the call should acknowledge, and the station requesting the call should be sure to let the other station know when they are clear.

    Emergency Calls: Stopping a Session
    Stopping a race or practice session should be reserved for emergency situations that greatly endanger the lives of competitors or safety crew workers. When the Captain feels that conditions make it too dangerous for racing to continue, the Communicator will contact Control and request that the race be stopped. ONLY CONTROL CAN STOP A SESSION!

    Reasons for stopping a session:
    • The track is blocked.
    • Track conditions make it too dangerous to continue.
    • An injured rider cannot be moved from a dangerous position.
    How to ask for session to be stopped:
      Station 1:  Control, this is station 1, stop the session, we have two bikes down on course and the track is blocked. (If Control does not respond to the request to stop the session, repeat the call.)
      Control:  Control to all stations, RED FLAG, RED FLAG, RED FLAG. (Control may ask for clarification before transmitting this message.)
    Once Control has called for the red Flag, all stations will display a waving red flag. (Red flags may only be displayed once the order has come from Control.) The station with the incident causing the red flag will proceed with standard reporting and clearing of the incident. Note that the red flag does not supersede other warning flags; the flaggers should continue to display appropriate flags until all riders have passed.
    • NEVER ask for a red Flag; ask for the session to be stopped.
    • NEVER use the word "red" on the net. The only person on the net who may say the word “"red" is Control when a session has been stopped. Use the word "crimson" to describe anything red in color on the network.
    • The red flag will be in the possession of the Communicator at all times while there are competitors on course. If the Communicator leaves the station at any time for any reason, the radio and the red flag will be turned over to the Corner Captain until the Communicator returns.
