Michael Joseph Luciw, 27, from Nottingham, was the passenger in a Ford Transit van when it was involved in a collision with a Mazda Premacy car near Junction 24 of the southbound carriageway.
The accident took place when the Mazda was driving the wrong way up the carriageway at about 2am on Monday, October 12.
Michael was pronounced dead at the scene - as well as the 87-year-old driver of the car, who has not yet been identified.
Michael’s mother, Andrea Shelton, and father, Stefan Luciw, have released a statement on behalf of the family.
They said: “It is with deepest sadness that Michael Luciw loving father, son, brother, uncle, grandson and nephew was sadly killed in the early hours of Monday morning on the M1 in a fatal car crash in which another person also died.
“We as a family would appreciate at this time to be left alone to come to terms with his loss. He was a huge part of all our lives and will be deeply missed. Thank you.”
The driver of the van was taken to Nottingham’s Queen’s Medical Centre where he remains in a stable condition.
The southbound carriageway of the motorway was closed off between J24 and J25 for more than 17 hours following the incident, as the crash caused “extensive damage” to the road.
A report from Highways England said: “It became apparent to the attending emergency services that this was a serious incident, with extensive clean-up, repair and recovery operations required.
“After liaison with Nottinghamshire Police, it was confirmed that the car involved in this incident was heading northbound on the southbound carriageway of the M1, prior to the collision.”
Anyone with information about the incident is asked to call police on 101.
