Ferrari's Lewis Hamilton finished second and Red Bull's Isack Hadjar completed the podium. Charles Leclerc's race ended early after a crash in the final corner during a restart, as his team-mate Hamilton moved into second in the drivers' championship. BBC F1 correspondent Andrew Benson answers your latest questions after Monaco. Why were so many cars caught out in the pit lane for speeding at Monaco? Was the software to blame? - John Five drivers were penalised for exceeding the 60km/h pit-lane speeding limit in Monaco on Sunday - Ferrari's Lewis Hamilton, Mercedes' George Russell, McLaren's Oscar Piastri and Alpine's Pierre Gasly and Franco Colapinto. That is an unusually large number, and of itself it implied something odd was going on. That impression only increased when the margins were published. All five drivers exceeded the limit by just 0.1km/h - though Gasly also went 0.4km/h over on one of his two offences. It seems this was caused by a combination of the layout of the pit lane and the way the limit is measured. At both entry and exit, there are white lines defining the fast lane of the pit lane, but there is also room to cut across these a little - and given F1 is all about exploiting fine margins, many drivers were doing so. At the same time, the pit-lane limit is not measured by a speed gun, but by a series of timing loops and the on-car transponders. As speed is a measure of distance divided by time, this opens the door to drivers going over the limit if they can find a way to shorten the distance, even if they were technically on or under the limit at all times. This appears to be what has happened here. Mercedes - for one - had instructed their drivers to go wide on the pit-lane entry to avoid this risk. But Russell obviously managed to trigger the limit anyway. The issue was discussed between the teams and governing body the FIA all weekend. All the drivers were adamant they had not exceeded the limit. As Hamilton put it: "I wasn't speeding. It's just the way the pit lane is. I've done this pit lane for years. "It's not like I came in and didn't press the button or something like that. Pit-lane limiter is on immediately. And I think it's just the line that you take, which is the same line we've all taken for years, where you come in, you kind of cut part of the white line. "I was shocked to hear that I was speeding because I wasn't actually above the speed. "It's all about, I think, the distance and something that we really need to look into because I heard lots of people got that today and they probably weren't really speeding. And having to do a stop-and-go, sort of stop and wait for five, 10 seconds, whatever people got, it destroys you on a track so sh
