Orange diver flag

State law requires that operators of a motorboat (other than a PWC) on the waters of the Mississippi River, the Missouri River, or Missouri lakes between the hours of 11:00 a.m. and sunset must clearly display a red or orange flag whenever a person enters the water before or after being towed on water skis or other similar devices.

  • The flag must be at least 12 inches x 12 inches in size.
  • The flag should not be displayed while the vessel is underway towing the person(s) on water skis or other similar devices.
  • PWC and moored or anchored motorboats are exempt from displaying the skier-down flag.
  • Vessel operators must not operate within 50 yards of a displayed skier-down flag.
