How do F1 Safety Car unlapping, restart and final-lap procedures differ?
Under the 2026 FIA Sporting Regulations, lapped cars do not all pass automatically. The Race Director must consider it safe and send the specified message, and only cars lapped at the rule's timing point qualify. A normal withdrawal has its own signal and overtaking limits. If the Safety Car is deployed on the final lap, B5.13.8 sets a default finish procedure and a Race Director exception.
For F1 viewers trying to understand which cars are permitted to unlap during a Safety Car period. · Updated
Only a defined group may unlap
Under B5.13.4(c), the Race Director must consider overtaking safe and send the message “LAPPED CARS MAY NOW OVERTAKE.” The green light on the Safety Car signals the eligible cars to pass the cars on the lead lap and the Safety Car.
Eligibility is fixed at a specific point: a car must have been lapped by the leader when it crossed the Control Line at the end of the lap in which it crossed the first Safety Car line for the second time after deployment. A car that became lapped only later is not included by that test.
After passing the lead-lap cars and Safety Car, the eligible cars continue at an appropriate speed without overtaking and make every effort to join the back of the queue. Lead-lap cars stay on the racing line while the pass is carried out unless they cannot avoid deviating from it. The Race Director may close the Pit Lane exit while the queue passes as the cars rejoin.
A normal withdrawal still has overtaking limits
Except for the lapped-car procedure, the Safety Car normally remains until the leader is behind it and the other cars are queued. After the lapped-car message, it returns to the pits at the end of the following lap unless the Race Director considers its presence still necessary.
When the Race Director decides it is safe to end the period, the message “SAFETY CAR IN THIS LAP” is sent and the orange lights are extinguished. The Safety Car enters the Pit Lane at lap end; the first car in line may set the pace and open a gap.
From the lights going out until the Safety Car enters the Pit Entry Road, drivers must avoid erratic acceleration or braking and moves likely to endanger others or impede the restart; no car may be driven alongside a car ahead during that interval. The general overtaking restriction remains until a driver passes the Control Line for the first time after the Safety Car has entered the Pit Entry Road, subject to the regulation's listed exceptions.
The last lap has a separate finish rule
If the Safety Car is deployed at the beginning of the last lap or during it, the default is for it to enter the Pit Lane at lap end and for the cars to take the end-of-session signal without overtaking before the Control Line. The Safety Car boards and yellow flags remain displayed; the chequered flag is shown at the Control Line.
The exception is explicit: if the Race Director deems the Safety Car must remain after the end-of-session signal, its orange lights stay on and the cars follow it across the Control Line, on track or in the Pit Lane as instructed. The chequered flag is shown, then the Safety Car leads the cars into the Pit Lane and Parc Fermé at the end of the following lap. This rule does not mean every race under Safety Car ends in the same way.
A fictional Safety Car sequence
Imagine anonymous Cars A and B at the timing point in B5.13.4(c): the leader has lapped A, while B becomes lapped only later. If the Race Director considers the track safe and sends the message, A is in the eligible group and B is not included by that timing test. A passes the lead-lap cars and Safety Car, then makes every effort to rejoin the queue. On a later ordinary withdrawal, the call-in message and orange-light signal begin the restart restrictions; overtaking generally remains barred until the first Control Line crossing after the Safety Car enters the Pit Entry Road. In a separate hypothetical final-lap case, the default is the Safety Car entering the pits at lap end, unless the Race Director requires it to continue after the end signal.

Do all lapped cars get to pass the Safety Car?
No. The Race Director must consider it safe and send the required message, and only cars lapped by the leader at the regulation's specified timing point qualify.
