Teams must run their two cars with essentially the same race livery throughout the season and must seek prior approval for any major changes.
In addition there are a number of requirements that apply to liveries for all cars and teams. Every car must carry its drivers race number, which must be clearly visible from the front of the car, and the drivers name must appear on the external bodywork of the car. The teams name or emblem must also appear on the nose of the car.
To help distinguish between a teams two cars, the onboard cameras which sit on top of the main rollover structure are coloured differently. On the first car it must be predominantly fluorescent red and on the second car it must be fluorescent yellow.
