Dramatic pictures show the bright yellow lorry crashed down an embankment after ploughing straight through a armco barrier.
The truck crashed into a ditch in the Gyor region of northwestern Hungary.
It came after both Nico Hulkenberg and Daniel Ricciardo failed to finish in Hockenheim.
Pictures show pieces of equipment spilled from the truck.
It is unknown if the lorry was carrying the team’s two RS19 F1 cars.
Other images show the central reservation also appears to have been flattened.
Firefighters and a rescue helicopter were called to the scene with a man trapped in the front of the truck.
The crash adds to the woes of the Renault team who have been struggling in 2019 despite a signing seven-time race winner Ricciardo.
The Australian’s car ground to a halt in Germany this weekend, while his teammate Hulkenberg crashed out from second place in the rain.
Speaking after the race, Daniel said: “But I know that getting angry and frustrated and bringing that kind of atmosphere and that energy into the room is not always very productive.
“So I think it’s for me to see the positives and to see the light.”
He added: “In a way, that’s also part of my job, to keep everyone up and happy and for sure if we’ve got things to improve I will tell them what I feel I need to, but also it needs to be constructive.”
Renault are now sixth in the constructors championship – being passed by rivals Toro Rosso and McLaren.
Ricciardo has retired five times in 11 races, and Renault have failed to place better than a sixth place in Canada.
The team have a winning pedigree – with two titles with Fernano Alonso in 2005 and 2006 – but have struggled to reach the sharp end of the grid since returning as a constructor in 2015.
