F1 track limits explained
How the white lines define the racing surface and why deleted laps differ from race warnings.
Quick answer
The white line normally defines the track edge. Leaving it can invalidate a qualifying lap or accumulate race infringements, but context such as avoiding an incident can matter.
Qualifying
A lap completed outside the defined track can be deleted, along with another lap where the sporting rules require it. Timing screens may therefore change after the car crosses the line.
The race
Repeated advantage outside the track can lead to warnings and penalties. Race control reviews incidents and any event-specific instructions.
Why detection varies
Circuits use combinations of cameras, loops, sensors and human review. The sporting standard is the rule, not the detection device.
