The FIA has elaborated on what is and is not permitted under the rules of its latest clampdown surrounding radio communications - and confirmed it extends to pit boards too.
On Monday the FIA issued a lengthy follow-up to the technical directive sent to teams last week, highlighting what can and cannot be said over the radio under the new rules either through pit boards or radio communications. It also stressed "any message that appears to be coded" will be specifically targeted.
Some rules will not be enforced until the Japanese Grand Prix in the interest of safety, to give teams the chance to get new fail-safe systems in place. Mercedes chief Toto Wolff has already predicted controversy around the new rules, though teams are expected to meet with the FIA in Singapore to discuss the changes further and clear up any grey areas.
