Tour de France to be proving ground for changes to UCI 3km rule, time gap calculations

The UCI announced three new measures to improve safety during road races on Wednesday, with subtle changes to the 3km rule, calculating time gaps in the peloton during sprint stages, and a new ‘yellow card’ system to punish repeat offenders breaking the rules during races.

The changes will be tested during the 2024 season, with “select stages” at the Tour de France being used as a proving ground for more flexible bunch sprint rules.
