A meeting of the FIA World Motor Sport Council has signed off on more rules tweaks, one week before the season-opening Australian Formula 1 Grand Prix.
The sport’s governing body has made minor alterations to the rules governing DRS use in wet weather, team curfews and tyre compound allocations.
A new restriction over the use of DRS has been employed for wet circuit conditions. The race director can now “prohibit the use of the adjustable rear wing (DRS) if he feels visibility is too poor in wet conditions.”
Last year’s rules were written that DRS could be activated on damp track conditions on the proviso that it was not raining, but the clarification closes a loophole as part of an ongoing safety push.
“One set of dry-weather tyres may now be carried over to Saturday if both Friday sessions are declared wet,” the second rules amendment reads.
“It is hoped that this will result in teams carrying out more laps [in] Saturday [practice].”
The final rules change governs the sport’s curfew regulations, which currently force teams to apply for permission to keep their mechanics and engineers working into the late hours.
Last year, several teams accidentally breached the curfew exceptions over the Singapore Grand Prix weekend; the schedule of which is run mostly at night.
“Changes have been made to the personnel curfew to ensure the rest periods remain constant throughout the season, irrespective of the timing of practice sessions at particular events,” the FIA statement reads.
