Frequently asked questions
When can a driver use DRS?
In Formula 1, DRS can only be used in pre-defined DRS zones and when the following car is within one second of the car ahead at the detection point.
Why is the undercut so powerful?
Because fresh tyres offer more grip and pace, an early stop can let a driver set much faster laps than a rival still on worn tyres, flipping track position when the rival pits.
What is the difference between a Safety Car, VSC, and Code 60?
Safety Car bunches the field behind the safety car, VSC enforces a speed delta without bunching, Code 60 sets a strict 60 km/h full-course limit.
Do the same flag rules apply in every motorsport series?
Core colours like green, yellow, red, blue, and chequered are broadly consistent, but some flags and procedures (such as Code 60) vary by championship and regulations.

Key race terms
- DRS (Drag Reduction System)
- A movable flap on the rear wing that opens in designated zones to reduce drag and increase top speed, used when a car is within one second of the car ahead.
- Undercut
- A strategy where a driver pits earlier than a rival to get fresh tyres, aiming to gain time on the out-laps and overtake when the other car stops later.
- Safety car
- A real car that leads the field at reduced speed when there is an incident or dangerous conditions, bunching the pack while marshals work safely.
- Virtual Safety Car (VSC)
- An electronic system that slows all cars to a set speed delta without deploying a physical safety car, used for less severe incidents.
- Code 60 flag
- A purple flag with a white “60” used in some series to enforce a 60 km/h full-course speed limit with no overtaking, as an alternative to a safety car.
- Apex
- The innermost point of the racing line through a corner; “hitting the apex” keeps the line as straight as possible and helps maintain speed.
- Backmarker
- A slower car being lapped by the leaders; backmarkers are shown blue flags and must let faster cars pass safely.
- Overcut
- A pit-stop strategy where a driver stays out longer than a rival, using clear air and strong pace to emerge ahead once they finally pit.
- Oversteer
- When the rear of the car rotates more than the driver intends so the car turns in more sharply, making it nervous but potentially fast if controlled well.
- Understeer
- When the front tyres do not grip as expected and the car turns less than the driver wants, pushing wide towards the outside of the corner.
- Pits / pit lane
- The area of garages and the adjoining lane where cars stop for tyre changes or repairs, with a strict speed limit from pit entry to pit exit.
- Slipstream
- The low-pressure air behind a car on a straight that reduces drag for a following car, allowing it to gain speed and set up an overtake.
