Formu♑la 1 teams will be prevented from using screens to hide their cars from their rivals and fans during winter testing, beginning from 2020.

The new rule is one of a number of changes agreed to the 2020 tec𓆏hnical and sporting regulations following Wednesday’s meeting of the FIA’s World Motor Sport 🌊Council.

In recent years teams have 𝔉taken advantage of a lack of regulation regarding displaying their cars during winter testing to put covers on their new challengers or hide them completely behind large screens while pre-season testing takes place.

But the more stringent rules - which also apply during grand prix weekends - will stop teams being able to hide their cars, with the FIA explaining the move is to “make thes༺e events more appealing to the media and fans”.

O𝄹ther changes approved by the FIA include reinstating the use of a physical chequered fl🥃ag to end grand prix races.

A chequered light panel system has been used since an error at the 2018 Canadian Grand Prix le🌌d to celebrity guest Winnie Harlow waving the chequered flag a lap early.

B൲ut a problem with the new electronic system led to the race distance at this year’s Japanese Grand Prix at Suzuka to be shortened by one lap, prompting a change for next season꧑.

Tweaks to the rules regarding the sampling and testing of fuel at events have also been made, while the FIA has confirmed three standard suppliers from 2021 in line with its increased push to reduceꦏ costs of competing in ꧂the championship.

BBS will provide wheel rims, with Magneti Marelli producing fuel-pr🧔imer pumps and Bosch tasked with the responsibility of sup💮plying high pressure fuel pump and piping.
