Formula One drivers have been told that if they gain a place by cutting a chicane, as Lewis Hamilton [Images] did in Belgium last weekend, they must hand it back and then wait at least one corner before overtaking.

Honda's Jenson Button [Images] said at the Italian Grand Prix on Saturday that the matter was discussed at the drivers' Friday briefing and a clarification given by race director Charlie Whiting.

A Ferrari [Images] spokesman said team managers have also been reminded of the position at their meeting on Thursday but stressed that the existing regulations remain unchanged.

Hamilton was stripped of victory by stewards in Belgium after he cut the Bus Stop chicane while battling Ferrari's Kimi Raikkonen [Images] for the lead.

The championship leader came out ahead of the Finn, ceded the position momentarily on the straight before emerging from his wake to overtake the Ferrari into the next corner.

Stewards decided the Briton had gained an advantage and imposed a retrospective drive-through penalty which translated as 25 seconds added to his time, demoting him to third place.

McLaren have appealed the sanction, which cut Hamilton's overall lead over Ferrari's Brazilian Felipe Massa [Images] to two points with five races remaining.

"Generally, it is pretty clear for people to probably not attack immediately again, which wasn't mega, mega clear in the past," said Australian Mark Webber [Images] after the drivers' briefing.
