F1 track limits explained: the rules, deleted laps and penalties

Where is the track limit?

The track limit is the white line along the edge of the track. A driver has left the track when no part of the car is still touching it: in effect, all four wheels are fully over the white line. As long as one wheel is still on the line, the driver is within track limits.

The white line itself counts as track, and so does any part of a kerb that lies between the white lines. Everything beyond the line — kerb, run-off or gravel — does not.

The Formula 1 regulations say drivers must make every reasonable effort to use the track and may not leave it without a justifiable reason. A driver who goes off may rejoin, but only safely and without gaining a lasting advantage over rivals. The FIA guidelines say the rule is strictly enforced, because it matters for both fair racing and safety. There is a short version in the chapter on flags, the safety car and penalties and in the glossary.

What happens in qualifying?

In qualifying and Sprint Qualifying, going beyond the white line gets the lap time deleted, even if it was the fastest lap of the session. The FIA guidelines add no penalty points or grid places for the offence itself: the lap simply doesn’t count.

Sometimes the next lap is deleted as well, if the excursion could have helped it too. At the 2026 Austrian Grand Prix the Race Director warned in advance that going off at Turn 10, the last corner of the Red Bull Ring, would cost both that lap and the following one.

If the driver gained time or a place by going off, that is a different offence: leaving the track and gaining a lasting advantage. In qualifying it costs the lap time, up to three grid places, or both. In free practice, going off can cost a deleted lap, a reprimand or both.

For other ways to lose a quick lap, see the qualifying article.

What happens in the race?

In the race and the sprint there is a three-strikes system: every time a driver leaves the track without a justifiable reason, the lap time is deleted and they get a strike. Under the FIA guidelines for 2026 the usual sequence is:

1. First and second time — the lap is deleted and the driver gets a strike.
2. Third time — the lap is deleted and the driver is shown the black-and-white flag with their car number.
3. Fourth time — a five-second penalty.
4. Every time after that — another five seconds.

The black-and-white flag is shown to a driver only once: it warns that doing it again will be penalised. The other black flags are covered in the flags article. The driver serves the five seconds at their next pit stop, standing still in their pit box, and if they don’t pit again the time is added to their finishing time. The details are in the penalties article.

The guidelines give no penalty points for the excursions themselves in any session. Whether to apply a strike is up to the stewards. If a driver left the track deliberately or in an unsporting way, they can be penalised straight away, without counting strikes.

What are the penalties for going off track?

The FIA penalty guidelines for 2026 separate four similar offences: leaving the track without a justifiable reason, gaining a lasting advantage by going off, rejoining unsafely and forcing another driver off. The penalties listed are the usual ones: the stewards look at each case on its own and may decide differently.

In free practice, the guidelines suggest a deleted lap, a reprimand or both for the first three offences in the table, and a reprimand or grid places for forcing a driver off.

What is a lasting advantage?

A lasting advantage is whatever a driver keeps over a rival after going off: time gained, a place gained or a place kept. You can’t rejoin the track and hold on to it. The Race Director may give the driver the chance to give back the whole advantage, for example by letting the rival back past.

Defending is a special case. Say a driver defending a place goes off or cuts a chicane and rejoins in the same position. The stewards will generally treat that as a lasting advantage, and the place should normally be handed back. Whether the driver was defending is for the stewards to decide.

Rejoining has its own rules too: keeping up racing speed across the run-off is not allowed, and cars on the track must not have to brake or change line because of the car coming back.

Not every trip off the track in a fight brings an advantage. At the start of the 2026 Barcelona-Catalunya Grand Prix, three cars went into Turn 1 side by side. Nico Hulkenberg and Arvid Lindblad both left the track; Lindblad rejoined ahead of both rivals but later let Hulkenberg back past. The stewards looked at how the cars were placed before braking and noted it was the first corner after the start. They found no lasting advantage and took no action.

When is going off not penalised?

When the driver had a justifiable reason to leave the track. The FIA Driving Standards Guidelines list the cases that don’t count towards the three strikes:

• the driver obviously lost control of the car;
• they went off to avoid a collision, such as at Turn 1 on the first lap;
• the stewards decide another car forced them off;
• they are already being penalised for that excursion, for a lasting advantage or an unsafe rejoin;
• the excursion happened in an incident penalised for another reason, such as causing a collision;
• they went off during an overtake, completed or not, but clearly gained nothing; here the stewards may decide not to give a strike.

One more rule works in the driver’s favour: the stewards must be satisfied that the offence is clear, and if there is any doubt, the driver gets the benefit of it.

How is going off different from being forced off?

Go over the white line on your own and you have broken track limits and, in a race, earned a strike. Push a rival off and you have broken the FIA driving code, which strictly forbids deliberately crowding a car beyond the edge of the track. It is the driver who did the pushing who is penalised, and the one forced off gets no strike.

In the race, forcing a driver off usually costs 10 seconds. If the stewards judge the move reckless, dangerous or deliberate, the penalty is harsher: a 10-second stop-and-go or more than 30 seconds added to the race time, plus 3 penalty points.

When an attacking car ends up beyond the white line, the overtaking rules decide who is to blame. The attacker is entitled to room in a corner only if they can make it within track limits. If the attacker has that right, it is up to the defending driver to avoid a collision or forcing them off. Other racing offences are covered in the penalties article.

Who checks track limits, and how?

Track limits are monitored by race control together with the FIA Remote Operations Centre, while the decisions are taken by the stewards. They are helped by a computer vision system that the FIA had rolled out by 2024. According to the FIA in 2025, it flags an offence within one second, and only 5% of cases need a manual review.

In the past the FIA also relied on timing loops in the asphalt, and the car itself estimated its position on the track. After Austria 2023 the FIA concluded that the loops were not accurate enough and kept them only at circuits with a chicane.

When the Race Director reports an excursion, the stewards publish a document listing the corner, the car number, the time of day and the deleted lap time. They may use any video or electronic means to reach their decisions.

Famous cases

Austria 2023: penalties after the flag

At the 2023 Austrian Grand Prix, track limits changed the final classification hours after the race. The Race Director had warned in advance that going off at the exit of Turn 10 would cost that lap and the following one. Penalties were handed out during the race as well: Lewis Hamilton got five seconds for his fourth excursion, after the black-and-white flag for the third.

The provisional classification came out at 16:55, and Aston Martin protested it, arguing that some offences had gone unpunished. The stewards noted that race control had dealt with more than 100 deleted laps. In all, the FIA had some 1,200 potential offences to check.

The protest was upheld. After the race the stewards added 12 penalties of 5 and 10 seconds for eight drivers, four of them for Esteban Ocon. The final list of deleted laps shows more than 80 offences, all at Turns 9 and 10.

That evening the stewards counted like this: four offences meant 5 seconds, five meant 10, and then, because of the sheer number of offences, the count started again. Carlos Sainz dropped from fourth to sixth and Hamilton from seventh to eighth. Fernando Alonso moved up to fifth and Lance Stroll to ninth, so Aston Martin left Austria 2023 with 12 points instead of 9.

In their decision the stewards very strongly recommended finding a solution for this circuit. By the 2024 race, a 2.5-metre gravel strip had been laid right behind the kerb at the exit of Turns 9 and 10. At several corners the white line on the kerb was moved and a light blue line added behind it, to make it easier to tell whether a driver was off.

The rule of deleting the lap and the next one for Turn 10 still applied at the 2026 Austrian Grand Prix. In the race the stewards deleted 18 laps, against more than a hundred in 2023.

Barcelona 2026: a late flag, but the penalty stood

At the 2026 Barcelona-Catalunya Grand Prix, Kimi Antonelli left the track four times. One of the earlier offences was spotted late, so he was shown the black-and-white flag only after his fourth excursion rather than his third. The stewards ruled that this did not exempt him from the rules and gave him five seconds after the race.

Antonelli did not reach the finish but was still classified 16th, with the penalty included in the final classification. The stewards also accepted that the guidelines might be unclear and recommended that the FIA review the procedures as soon as possible.
