Track limits for this weekend's Spanish GP have been outlined by the FIA.
With the Circuit de Barcelona-Catalunya being a more old-school venue than Bahrain and Portugal, the limits are largely defined by gravel and grass but there are still some opportunities for the drivers to take advantage, meaning Race Control has had to intervene to lay down some rules.
In particular, Turns 1 and 2 have been picked out for enforced track limits.
However, this applies to the run-off area which is on the outside of Turn 1 and inside of Turn 2. As it's not beneficial to run wide to gain time here, it's unlikely that these will cause significant issues for enforcement over the race weekend.
Instead, these areas have been chosen to ensure that drivers have to drive around a bollard on the approach to Turn 3 before rejoining the track safely.
If they run wide and simply rejoin without going around the bollard on two occasions during the race, they will referred to the stewards.
Further around the track, the kerbs at Turn 8 have been extended backwards towards the exit of Turn 7. This is to ensure the drivers can't straight-line the exit of Turn 7 as much as has been seen in recent years. With the kerbing in place, there are no plans for further enforcement.
At the end of the lap, drivers have been warned to ensure they use the correct circuit layout. This means the chicane that's been in place since 2004, and not to use the old Turn 13.
