Supt Sean Bell of Northamptonshire Police said: "Please leave your sat nav at home and follow event information signs which are clearly signposted on motorways and major trunk routes."
He said closing the A43 between Northampton and Oxford to through traffic for three days means arrangements have been made to help all road users over the weekend.
He advised fans to still allow extra time for journeys in and out of Silverstone and to be patient if there were delays.
