The formation lap sets the order; lights out starts the Sprint or Race.
Published
In a normal Formula 1 start, green lights release the grid for one formation lap, pole position leads the field back to its boxes, and five red lights illuminate one second apart. The Sprint or Race starts only when the permanent starter extinguishes all five red lights.
Quick ruling: under FIA 2026 Formula 1 Sporting Regulations Section B, Issue 08 dated 5 August 2026, Articles B5.4–B5.11 control the pre-start sequence. A safety problem can instead produce a delayed start, an extra formation lap, an aborted start, safety-car formation laps or a suspended starting procedure; those are different procedures with different effects on order and distance.
The FIA Formula One World Championship rules used here
This page applies the FIA 2026 Formula 1 Regulations, Section B: Sporting Regulations, Issue 08, approved by the World Motor Sport Council on 3 August and dated 5 August 2026. The FIA uses the term Total Time Classified Session (TTCS) for sessions classified by total elapsed time; that includes the Sprint and the Race. For readability, this page says “session” where the same start rule applies to both.
These rules do not automatically govern Formula 2, Formula 3, Formula E or another racing series. The Race Director also has authority over the starting procedure and may issue event instructions through official circulars. A circuit-specific instruction can supplement the baseline without making it a universal F1 rule.
Three laps viewers confuse
Reconnaissance, formation and first racing lap are different
Reconnaissance lap: before the grid countdown, cars leave the pit lane to reach the grid. For a Race, the exit opens 40 minutes before the formation lap and remains open for ten minutes; a Sprint has a 30-minute opening and a five-minute window. Articles B5.2.2–B5.2.5 govern these laps.
Formation lap: the green gantry lights release the grid under Article B5.6. It prepares and orders the field, but the normal session has not started.
First racing lap: after a normal standing start, it begins when all five red lights go out under Article B5.7.2. A rolling start has a different trigger: the leader crossing the Line after the Safety Car has entered the Pit Entry Road.
Normal procedure
From grid countdown to lights out
Articles B5.5–B5.7 create a sequence, not one instantaneous start.
1 · Grid signals
Ten, five, three, one, fifteen
Audible signals accompany the ten-minute, five-minute, three-minute, one-minute and 15-second warnings. At five minutes every car on the grid or in the pit-lane Fast Lane must have its wheels fitted, tyre blankets on fitted wheels must be disconnected, and teams must begin clearing the grid. At one minute engines should start; personnel and equipment must be clear by 15 seconds.
2 · Formation lap
Pole leads away on green
Cars able to leave do so behind pole position. They must respect the pit-lane speed limit until passing pole position, may not make practice starts, and must keep the formation as tight as possible. Article B5.6 does not give a driver permission to break the order merely to create a preferred gap.
3 · Standing start
Five red lights, then all out
Grid starters return to their allocated boxes with engines running. Once all have stopped, the five red lights illuminate sequentially at one-second intervals. The permanent starter chooses the interval after the fifth light; extinguishing all five is the start signal.
Delayed on the formation lap
Passing is allowed only to restore the starting order
Article B5.6.4 permits overtaking only when a car is delayed and cars behind cannot avoid passing without unduly delaying the rest of the field. The permission is corrective: drivers may pass only to re-establish the original starting order.
The delayed driver must recover the original place before reaching the first safety car line. If not, the driver must enter the pit lane and start from its end. Ignoring that obligation brings the prescribed Stop-and-Go Penalty. The rule does not give a delayed driver the whole lap—or the run back to the grid—to recover.
Pit-lane starters
They can join the formation lap, not the grid start
Under Articles B5.3, B5.6.1 and B5.7.3, a pit-lane starter waits in the Fast Lane. Once every car on track has passed the end of the pit lane, the exit opens and pit-lane starters join the formation lap in the prescribed order. They must return to the pit lane at the end of that lap, proceed at constant speed and throttle, and stop at pit exit.
They may join the session only after the on-track field has passed the end of the pit lane for the first time after the start. If several cars start there, the normal Sprint or Race starting order applies, except a car arriving after the five-minute signal goes behind cars already waiting at pit exit.
Start problems
Delayed, extra or aborted?
The decisive facts are whether the formation lap has begun and whether the problem requires a full reset.
Delayed start · B5.4
Formation lap has not started
If the Race Director delays the session during the grid procedure, orange gantry lights and a “DELAYED START” board and message are shown. The procedure restarts at the ten-minute signal. No completed delayed-start procedure is specified to remove a lap.
Extra lap · B5.9
Danger, but no full abort
After the formation lap has begun, a problem that could endanger the start but does not require an abort can trigger “EXTRA FORMATION LAP.” Two seconds after that signal, green lights release the field again. Each completed extra-lap procedure shortens the Sprint or Race by one lap.
Aborted start · B5.8
Danger requires a full reset
After the formation lap has begun, the Race Director may abort a start that could be endangered. Cars hold their grid or pit-lane positions, team personnel and equipment may return, and a new start begins from the ten-minute signal. Each completed aborted-start procedure shortens the session by one lap.
The car that caused it
A repaired car normally loses its grid start
If a driver causes an aborted start and can continue, Article B5.8.2 requires a start from the end of the pit lane. Article B5.9.4 applies the same outcome to a driver who caused an extra formation lap: even if the car can take the extra lap, it must enter the pit lane at that lap's end and start from there. Failure to do so carries a Stop-and-Go Penalty.
If a car is immobilised on the grid, the driver must raise both hands. Marshals warn the rows behind and, when safe, push the car to the pit-lane Inner Lane. The driver may not try to start it while it is being pushed; the team may try once it is in the Inner Lane, and a successfully restarted car can enter the Fast Lane only after the session has started (Article B5.7.1).
Compact decision path
How to read the race-control signal
Has the formation lap begun? If no, a delay falls under B5.4 and resets at ten minutes.
Could the problem endanger the start? If no, the normal B5.7 sequence can continue with local yellow warnings as necessary.
Is a full reset required? If no, B5.9 permits an extra formation lap; if yes, B5.8 permits an aborted start.
Which car caused it? A repaired causal car must start from the end of the pit lane.
Was a procedure completed? Each completed extra-lap or aborted-start procedure removes one lap.
Are conditions unsuitable for any normal start? Move to the safety-car formation or suspended-start rules rather than treating it as an ordinary extra lap.
Unsuitable conditions
Formation laps behind the Safety Car
Articles B5.10 and B5.14 cover the route from unsafe conditions to a standing start, rolling start or suspension.
Following distance
Ten car lengths, or twenty
The field follows the Safety Car in grid order with no more than ten car lengths between cars. In poor visibility the Race Director may increase the maximum—including the leader's gap to the Safety Car—to 20 car lengths and issue the specified low-visibility message.
Tyres
Wet-weather tyres are conditional
The Race Director may mandate wet-weather tyres and send “FORMATION LAP(S) BEHIND SAFETY CAR – WET WEATHER TYRES MUST BE USED.” If wet tyres are not mandated, the separate safety-car formation-lap message is given at the five-minute signal. A start behind the Safety Car does not by itself make wet tyres compulsory under Issue 08.
Distance
Safety-car laps minus one
If the formation laps start behind the Safety Car, Article B5.10.7 shortens the Sprint or Race by the number of Safety Car laps minus one. Four formation laps behind the Safety Car therefore reduce the scheduled distance by three laps, not four.
Standing or rolling
The Safety Car does not decide how racing begins
Standing start — B5.10.8: if conditions become suitable, the “STANDING START” message and “SS” light panels are shown. The Safety Car pits, grid starters return to their boxes, and the five-light procedure in B5.7 follows.
Rolling start — B5.10.9: if a standing start remains unsuitable, “ROLLING START” and “RS” are shown. No overtaking is allowed until a car passes the Line after the Safety Car enters the Pit Entry Road. The session starts when the leader crosses that Line.
Pit-lane starters: in either case they must re-enter the pit lane after the Safety Car returns and wait for pit exit to open after the start.
Conditions worsen further
The starting procedure can be suspended
If conditions become unsuitable to start after safety-car formation laps have begun, Article B5.14.1 requires the “STARTING PROCEDURE SUSPENDED” message, red flags and a return to the pit lane behind the Safety Car. This is not an aborted start under B5.8.
The resumption order and countdown then come from B5.15. A significant boundary changes: following a suspension of the starting procedure, the session starts when pit exit opens at the resumption, and every lap completed in that resumption procedure counts. That differs from the B5.10 “Safety Car laps minus one” calculation used before a suspension.
False start · B5.11
Movement, detection and grid-box position are separate tests
For a standing start or standing-start resumption, Article B5.11.1 requires all cars to meet all three conditions:
Remain stationary in the allocated grid position from after the third red light is illuminated until all red lights go out.
Be positioned so the transponder can detect the moment the car first moves after the start signal.
At the start signal, have no part of either front tyre's contact patch outside the front or side lines of the allocated box.
The stewards may impose a 5-Second Penalty, 10-Second Penalty, Drive-Through Penalty or Stop-and-Go Penalty. Issue 08 does not prescribe one automatic sanction for every breach; the choice is expressly left to the stewards.
What the box test means
A bad position can breach the rule without an early launch
The grid-position test is not limited to the nose of the car and is not phrased as “touching a painted line.” It asks whether any part of the front tyre contact patches is outside the front or side boundaries when the start signal is given. Separately, the car must be placed so the transponder can detect its first post-signal movement.
That is why “the driver did not jump the lights” is not a complete defence to every B5.11 investigation: stationary position and reliable detection are independent requirements.
Worked rulings
Four start situations under FIA Issue 08
These are illustrations of the published rules, not claims about real races or official casebook decisions.
Case 1 · Delayed car
The driver recovers too late
Situation: Car 8 is passed after leaving the grid and does not regain eighth place before the first safety car line.
Ruling: under B5.6.4, Car 8 must enter the pit lane and start from its end. Rejoining eighth on the rest of the lap does not cure missing the deadline; failing to pit brings a Stop-and-Go Penalty.
Case 2 · Extra lap
The causal car is repaired
Situation: a grid car triggers an extra formation lap, restarts and can follow the field.
Ruling: B5.9.4 still requires it to enter the pit lane at the end of that extra lap and start from there. The completed procedure also removes one lap from the session.
Case 3 · Safety Car
Four laps, then a standing start
Situation: the field completes four formation laps behind the Safety Car before “STANDING START” is called.
Ruling: B5.10.7 reduces the scheduled distance by three laps—four minus one. The cars then take the grid and the session begins at lights out under B5.10.8 and B5.7.
Case 4 · Grid box
The car is still but too far sideways
Situation: a car never moves before lights out, but part of a front tyre's contact patch is outside a side line when the red lights are extinguished.
Ruling: that is a B5.11.1 grid-position breach even without an early launch. The stewards choose among the four penalties listed in B5.11.
Common misunderstandings
Claims the 2026 rules do not support
“Green lights start the race.” In the normal procedure they start the formation lap; all five red lights going out start the session.
“Every start problem is an aborted start.” Timing and severity separate delayed, extra-lap, aborted and suspended-start procedures.
“Pit-lane starters skip the formation lap.” They may join it, but must return to the pit lane and wait for the field to start.
“Every Safety Car start is rolling.” Race control can select a standing start when the track is suitable.
“Wet tyres are always mandatory behind the Safety Car.” Under Issue 08 they are mandatory only when the Race Director sends the specified wet-tyre message.
“A false start only means moving before lights out.” Transponder detection and front-tyre contact-patch position are separate B5.11 requirements.
Checked on 26 August 2026 against the FIA's current published Section B issue. Issue 08 is dated 5 August 2026 and records WMSC approval on 3 August 2026. Event-specific Race Director instructions may supplement operational details; other FIA championships use their own sporting regulations.
