A crushed car has fallen off a lorry near the M1 on the Nottinghamshire and Derbyshire border.
It happened on the Stapleford and Sandiacre roundabout near J25 of the motorway at about 06:25 BST.
Highways England told the BBC the driver of the transporter may not have been aware it had fallen off.
It said one lane on the roundabout was closed, causing delays during morning rush hour on the approaches and between J26 and J25 on the M1.
Normal traffic conditions had resumed by about 09:00 BST, it added.
