The first cars are approaching the Gumball checkpoint in Dubrovnik. You can see the cars arrive at the webcam in Dubrovnik! This years checkpoint location is the same as back in 2005 when the cars stopped in Dubrovnik before taking the ferry to Italy.
Update 15:01 CET:
It seems a lot of teams skipped the checkpoint, while others are having lunch in Dubrovnik. The live tracker keeps you informed on the next stage from Dubrovnik to Bratislava.
