Rolling starts in multi-class racing require careful orchestration to maintain order and safety among different vehicle classes.
Unlike single-class racing, where all vehicles have similar performance characteristics, multi-class racing involves managing multiple groups of cars with distinct speed capabilities and handling characteristics.
The fundamental principle is straightforward: before the green flag, all drivers must maintain their respective positions within their designated pace lines. This rule applies universally, regardless of vehicle class.
Official Rules and Regulations
The official regulations governing multi-class rolling starts are designed to ensure fairness and safety.
The key rules include:
- Drivers must maintain their position in their respective pace line until the green flag is shown. This applies across all classes, treating the start as if it were a single-class race.
- The overall pole position holder has the privilege of starting the race once the pace car enters the pits. No other driver may pass before the green flag, regardless of their class.
- No car classes may start the race until the faster class has started or the green flag is waved.
- Second place overall must remain behind the leader until the green flag, while all other competitors must maintain their lane position relative to the cars ahead.
Class Position Guidelines During Rolling Starts
Position management during rolling starts requires careful attention to several key factors. Drivers must understand and respect their place in the overall grid while maintaining awareness of their class competitors. The rules are clear: no passing is allowed before the green flag, even between different classes.
Inter-class spacing is a critical consideration. While the rules don’t mandate specific gaps between classes, it’s common practice for drivers to leave reasonable space between different classes during the formation lap. This spacing is typically maintained through driver courtesy and mutual agreement rather than official regulations.
Specific position guidelines include:
- Drivers must stay in their assigned lane
- No weaving or position swapping before the green flag
- Maintaining consistent speed with the pace car and lead vehicles
- Respecting the overall grid position regardless of class
Special Considerations
Weather and track conditions can significantly impact multi-class rolling starts. Wet conditions require extra caution and often lead to larger gaps between classes. Different vehicle classes may also have varying levels of performance in adverse conditions, which must be factored into start procedures.
Track characteristics also play a crucial role. Some circuits may require modified procedures based on:
- Start/finish straight length
- First corner configuration
- Track width
- Surface conditions
- Banking or elevation changes
Frequently Asked Questions
Q: Can slower class cars pass faster class cars before the start?
A: No, positions must be maintained within each pace line until the green flag, regardless of class.
Q: What happens if a car ahead is significantly slow during the start?
A: If a car is obviously slow or stopped, following cars may be directed by race control to pass safely, but this is an exception rather than the rule.
Q: How are penalties enforced for start violations?
A: Many racing series use automatic detection systems for start violations, with penalties applied during the race. Additional violations may be subject to post-race review and protests.
Remember, successful multi-class racing starts require a balance of aggression and restraint, always prioritizing safety while maintaining competitive positions. With proper understanding and application of these rules and guidelines, drivers can contribute to exciting and safe race starts in multi-class competition.

Regarding “The overall pole position holder has the privilege of starting the race once the pace car enters the pits” it should be mentioned that the leader takes over control and is allowed to drive past the pace car, as soon as it has left the so called “racing surface”.
Depending on the track, the racing surface is extended quite far into the pit entry part of the track, so overtaking the pace car immediately after it turns into the direction of the pitlane will lead to a penalty for the pole position holder.
The end of the racing surface is marked visually by a line at the pit entry, which the pace car has to have passed before the pole position leader could savely accelerate past the pace car when starting.
