Victory Road is the path that leads to the Elite 4 in Pokemon Diamond version. To get past it, you need to have all the badges.
First, you have to get through Victory Road. Before you can exit Victory Road, Rival will challenge you to a battle. After you defeat him (if you do defeat him) you can exit Victory Road and enter the Pokemon League. Then you defeat the Elite Four and Champion.
The best way to get past victory road in Pokemon Diamond is to buy lots of max repels and have a Pokemon that know the moves rock smash and strength.
