How do the safety car and the virtual safety car (VSC) work?

Q: When is the safety car deployed?

If there is immediate physical danger for competitors or officials. It is used only in the case of immediate physical danger on or near the track.

Q: What distinguishes the VSC from the safety car?

No car comes out and the field is not bunched. With the VSC drivers respect a minimum time per sector, with no safety car and no bunching of the field.

Q: What do lapped cars do when the race director orders it under a safety car?

Overtake the field and take their place at the back. When it is safe, they pass the field and take their place at the back.

When the safety car comes out, what lapped cars do, how the race restarts and how the VSC differs.

In 30 seconds

The safety car comes out only if competitors or officials are in immediate physical danger on or near the track; the field bunches up behind it.
The VSC puts no car on track: drivers must respect a minimum time per sector, and the field is not bunched.
With either, pitting costs much less time than under green flag.

Step by step

When it comes out
The race director deploys it only if competitors or officials are in immediate physical danger on or near the track. It is signalled with yellow flags, safety-car boards and "SC" on the illuminated panels.
The field bunches up
The safety car's job is to bunch the cars and slow the race while the danger is cleared.
Lapped cars
When it is safe, the race director orders lapped cars to overtake the field and take their place at the back. In 2021 the regulations did not make this mandatory, which fuelled the Abu Dhabi controversy; it was clarified afterwards.
Pitting gets cheaper
A stop under green flag costs between 20 and 25 seconds; under a safety car or VSC the loss is much smaller.
The VSC
The safety car does not come out on track and the field is not bunched: drivers must stay above a minimum time set by the FIA at least once in each sector, and cannot enter the pits except to change tyres.
How it ends
The safety car returns to the pits at the end of the lap after the notice, with its lights off. The VSC ends when the panels turn green and you can race immediately.

Glossary for this page

Safety car: A car that comes out on track after an incident so the cars lap slowly and bunched while the track is cleared.
Virtual safety car (VSC): A neutralisation in which all cars must stay below a set time, without the safety car coming out on track.
Lapped car: A driver whom a leader has put a full lap down. They must let the fastest car through when shown the blue flag.
Yellow flag: Danger on track: slow down and do not overtake in that zone.
