The speed limit in the pitlane is now officially 80 km/h over the course of grand prix weekends after the rule was ratified by the World Motor Sport Council.
The regulation was initially set to be changed for the 2014 season, but the tweak was brought forward after FOM cameraman Paul Allen was injured during a pitlane incident at the German Grand Prix.
A loose wheel from Mark Webber's Red Bull went flying through the air and struck Allen down, leaving him with a broken collarbone and ribs.
The FIA then decided to bring the regulation charge forward and the speed limit has been reduced to 80 km/h (49.7 mph) from the Hungarian Grand Prix onwards as opposed to the 100 km/h (62.1 mph) it was before the incident.
The Australian, Monaco and Singapore Grands Prix, though, will continue to have a stricter speed limit of 60 km/h (37.2 mph) because of the nature of the circuits.
The WMSC also confirmed that all team members who work on a car during pit stops must now wear head protection.
