How to Start Racing - buy your copy & accelerate up the grid

Racing Marshals use flags to communicate critical information to inform racing drivers what action they must take when on circuit e.g. track conditions, hazards and penalty situations.  

It's imperative racing drivers know the meaning of each flag, as well as the different ways they are used. Understanding what each means with the action they are required to take, helps the sport to be safe.

FIA sanctioned racing flags are the most commonly used in both UK and International auto racing. Their meanings cover well-known championships such as Formula 1 and the FIA World Endurance Championship. The use of the Chequered Flag to signal the end of a session is common across most forms of motorsport. However, other Status or Penalty Flag meanings may differ from series to series. For example, in NASCAR and Indycar they use a black flag with a white saltire to indicate a driver is disqualified. In addition, the Blue Flag is not used in rally or rallycross racing series. 

The Association of Racing Drivers Schools (ARDS) test includes a written exam on Racing Flags.  This guide will help you prepare for your Competition License and/or give you more understanding about the sport.

History of Racing Flags

The first recorded use of undoubtedly the most famous racing flag - the iconic chequered flag - is a topic of debate. However, one of the earliest known, was at the 1906 Glidden Tours.

Created by the American Automobile Association (AAA), the promotional events aimed to make the automobile more relatable to the general public. The tours ran from 1902 - 1931 across the US and sometimes into Canada. The courses ran for several hundred miles and were split into timed sections. At each course 'checking station', a chequered flag was used to mark the location of the race officials, known as 'checkers'. The man behind this system was Sidney Waldon, an employee of the Packard Motor Car Company. The 1906 Glidden Tour was the first recorded use of the chequered flag to indicate the end of a race.

Sidney Waldon was also a member of the organisation committee of the Vanderbilt Cup Races. A successful road race that ran from 1904 - 1916, responsible for the Vanderbilt Cup - the first major trophy in American auto racing. The 1906 Vanderbilt Race in New York is one of the first pictures to capture the chequered flag being used to end a race.

LED Flag Panels

Some major racing leagues, such as F1, now employ a marshalling system, replacing flags with LED Flag Panels.

The signals used on the flag panels are the same as traditional marshal circuit flags. Each marshall's post has a control unit operating the flag panel signals in their sector, allowing them to stay at safer distances from the action on track. The drivers also have a display screen on their steering wheel, with flag notifications. This ensures immediate knowledge, allowing fast reaction, potentially avoiding incidents and getting back on the pace once it is safe to do so.
