The driver died at the scene in Netherfield Lane near the A614.
Police said a lorry was seen “discarding its load” in the area.
Louise Melbourne, from Nottinghamshire Police’s Serious Collision Investigation Unit, said: “A driver has lost their life as a result of this incident and we will do everything we can to get to the bottom of how that happened.
“We are appealing for anyone that may have seen a large beige coloured cabbed truck that may be discarding its load in the area around the time of the collision. We are also appealing for any dashcam footage which may show this vehicle.”
Anyone who has information which could help the investigation should call Nottinghamshire Police on 101, quoting incident number 275 of 7 July 2020.
