Castle Combe Circuit, Chippenham has postponed all large public events planned at the Wiltshire venue in June.
These will be rescheduled if possible but individual private test days will be possible by arrangement to ensure there is no overcrowding and participants meet social distancing guidelines.
It means a race meeting planned for 13 & 14 June will not be held in accordance with the Motor Sports Association ban until early July, when the British Grand Prix is due to be staged at Silverstone if the law permits.
Specific days for rallycars and German sports cars will be pushed back into the year and all spectator passes for 2020 will be valid to end of 2021.
