Question 1 of 9
What is the broad meaning?
THE REFERENCE BOARD
Recognition comes before response details.
Red
The session or race is interrupted; reduce pace and follow officials.
No overtaking; follow the prescribed route and instructions. It is not permission to stop unpredictably.
Green
Clear after a yellow-controlled danger area; also used on formation or practice laps.
Its context matters. Do not treat every green display as an instruction to start racing.
Yellow / red stripes
Surface grip may be reduced.
Check the event rules for stationary and waved displays.
Blue
Another competitor is close behind or trying to pass.
Stationary and waved displays differ. Overtaking procedures come from the applicable event rules.
White
A slow or service vehicle is present.
The signal can identify its sector. Read the full display rules rather than assuming it refers to weather.
Black
A pit and reporting instruction for the identified driver.
Vehicle identification and the required response matter; use the current rules and briefing.
Black / orange disc
An apparent technical problem for the identified vehicle.
The driver must respond under the applicable pit/repair instruction; this is not just a caution about grip.
Chequered
The race or practice has ended.
Follow the event’s return and cooldown instructions. It is not a signal to stop on the circuit.
