Track day flags - which ones and what they mean.

Track day flag signal: Perhaps the most important thing you'll see on a track day.

Seeing red?  How about blue, yellow, black?

On any race circuit the only way organizers and safety marshals have to communicate with those on the track is via a series of flags. Safety is the key here, pretty much all of them are related to keeping you safer so it's important you know what they mean. It's not optional to obey any flag either (you'll be banned for life if you don't) so just as important is knowing what you must do if you see one. We've compiled this guide as an introduction, but never let that distract you from paying close attention in any safety briefing - each track and organizer may differ slightly, so use this as a general guide - not a gospel replacement for paying attention at the beginning of the day.
