The police warned that they expected, even with additional resources including an extra 20 roads policing officers, the departure process would be slow-going.
Chief Constable Alex Marshall, who visited the site and spoke to festival-goers on Friday night into Saturday morning, said: "It was a wet and muddy start for many campers this year, but thankfully the weather did not seem to dampen the festival spirit on site.
"I’d ask that those heading home by car drive sensibly and carefully. Due to the volume of traffic on the site drivers should expect some delays and we would ask you to be patient and remain with your vehicles, as the organisers work to get you home.
"The unprecedented impact the rain had on the site brought with it a unique challenge in the festival’s 11-year history and our officers, PCSOs and staff worked hard alongside Solo and our partner agencies to tackle the situation as quickly as possible."
Police urged drivers to take care in muddy conditions.

Mr Marshall said: "I’d like to thank festival-goers for their patience while the festival’s Emergency Liaison Team has dealt with and will continue to deal with what has been a very challenging situation."
