Mercedes and McLaren will take part in a test on the national circuit on 13 July with the Wellington Straight to be artificially soaked to allow the FIA to gather data on the arches or “mudguards”.
The idea emerged after the 2021 Belgian GP at Spa as a way of allowing races or sessions to proceed in conditions that would normally be regarded as too dangerous due to poor visibility.
However, the accident that befell Formula Regional driver Dilano van ’t Hoff at the same venue last weekend has put a further focus on the issue.
If successful in F1 the arches are likely to be introduced into the junior categories.
"I think visibility in the rain is critical,” said Pierre Gasly when asked about the subject by Autosport.
“Unfortunately what's happened in Spa. I even had a conversation with Esteban [Ocon] on the parade [in Austria], and we had a very similar situation in 2012 Formula Renault two litres, where we both started from the back of the grid in similar conditions.
“And to be fair, you're praying for your life that no one stopped in the middle because you can't even see five metres ahead of you.
