Was any part of the car still on track?
The white line counts as the track edge. Kerbs do not extend the track unless the event notes or regulation wording say otherwise. If no part of the car remains on track, the driver has left the track.
Formula 1 - Track limits
Track limits are about the white line, not the kerb.
Track limits decide lap times, warnings, race penalties, and post-session results. The basic idea is simple: drivers must keep at least part of the car on the track, and the white lines define the track edges. The hard part is what happens after the car leaves.
Decision path
How officials check track limits
Start with the car's position, then separate practice, qualifying, sprint, and race consequences.
Which session is it?
In practice and qualifying, the usual consequence is a deleted lap time. In races, repeated offences can create warnings, a black-and-white flag, and time penalties.
Was an advantage gained?
If a driver leaves the track and gains a lasting advantage, the stewards can require the place back or apply a penalty even if the incident is not just a simple lap-time deletion.
What fans usually mix up
- Kerb contact is not enough: a car can be on the kerb and still be outside track limits if it has fully crossed the white line.
- Deleted lap times are not always penalties: in qualifying, the lap can simply stop counting without adding a separate race penalty.
- Race warnings are cumulative: a driver can be fine once, warned later, and penalized after repeated offences.
- Being forced wide matters: a driver pushed off by another car may be judged differently from a driver who runs wide alone.
- Timing loops do not replace stewarding: automated detection can flag an incident, but context can still matter.
What changes the result
- Practice or qualifying: expect lap-time deletion first.
- Race: expect warnings before a penalty unless the driver gains a clear advantage.
- Overtaking off track: the driver may need to give the place back.
- Defending while off track: the stewards ask whether the driver kept a lasting advantage.
Position, session, and consequence are separate questions
This explainer applies the FIA 2026 Formula One Regulations, Section B: Sporting Regulations, Issue 07, published 25 June 2026, together with the FIA instructions issued for the competition. Start by identifying the boundary being monitored at that corner. Then establish the car's position at the relevant instant. Only after that should the session and sporting consequence enter the analysis.
A television picture can be useful without being conclusive. Camera angle, lens compression, an obscured tyre, and the exact white-line geometry can all make a marginal position difficult to judge. The official timing message or stewarding document is the result to record. In qualifying, also check whether deletion of one lap affected the next lap under the applicable instruction. In a race, keep a simple infringement count separate from an incident in which leaving the track produced a lasting advantage.
Record a disputed track-limits call in this order
- Corner and lap number.
- Boundary defined by the FIA regulation or event instruction.
- Official detection or stewarding message.
- Session-specific result: deletion, warning sequence, place return, or penalty.
- Effect on the classification, including any later reinstatement or review.
