How to ensure that your start numbers comply with competition rules

Bib numbers are not just a visual identifier – they are a fundamental part of the competition rules in motorsport. However, the rules for bib numbers can vary between different organizations and competition formats, making it important to be well prepared. Here we go over what you need to know and answer common questions.

1. Know the most important associations and their rules

The rules for starting numbers vary depending on the sport and competition organizer. Here are some of the largest associations and their guidelines:

• SVEMO (Swedish Motorcycle and Snowmobile Association): Covers motocross and enduro in Sweden. For example, they require that the numbers be at least 10 cm high and be placed clearly on the front of the vehicle and side covers.
• FIA (International Automobile Federation): Responsible for international rally rules. Start numbers on rally cars should usually be 15–20 cm high and placed on the doors.
• SBF (Swedish Motorsports Association): Responsible for folk racing, rallycross and karting in Sweden. Folk racing requires clear numbers on both the roof and doors, often with a recommended size of at least 20 cm.

2. How to choose the right size and color

To ensure clarity and regulatory compliance, it is important to choose the right size and color combination.

• Motocross: Numbers at least 10 cm high, often black text on a white or yellow background.
• Rally: Numbers of 15–20 cm and contrasting colors such as white on black.
• Folkrace: Larger numbers (at least 20 cm) with clear backgrounds, for example black text on a white background.
