Formula One's 10 teams will be limited to a maximum 80 people each at races held without spectators when the delayed season gets going in July.
Revised 2020 sporting regulations published by the governing International Automobile Federation (FIA) detailed the conditions for such 'closed events'.
"From the start of a closed event until the declaration of the official classification of the race, no competitor may have more than a total of 80 team personnel within the confines of the circuit," the rules said.
