What are track limits in F1?
I · Intermediate · Racing · 4 of 6A single waved yellow means slow and be ready to change line; a double means slow sharply and be ready to stop. A car has left the track when no part touches it; the white lines are track, the kerbs are not. A driver may re-join but must not keep any lasting advantage.
How it works
- Single yellow: slow, be ready to change line.
- Double yellow: slow, be ready to stop.
- Qualifying lap: deleted under double yellow.
- Track: white lines included.
- Kerbs: not track.
- Off: no part on the track.
- Re-joining: when safe.
- Advantage: given back.
The glossary has the yellow flag, the track limits, the stewards, the chequered flag, the low grip conditions and the heat hazard and rain hazard.
Tricky cases
Two wheels on the kerb, two on the line. Off the track?
No. Part of the car touches the track.
A driver gains a place by cutting a chicane. Result?
They may be told to give it back.
What does a double yellow do in qualifying?
Deletes that lap.
Who decides penalties for track limits?
The stewards.
Why the rule exists
Track limits stop drivers cutting corners for lap time.
