Victoria Kavanagh, a mother-of-two from Oldbury, was driving on the northbound carriageway of the M6 between Wednesbury and Walsall shortly before 9am on July 27 when she was involved in the smash.
Opening the inquest into the 41-year-old's death, senior coroner for the Black Country Zafar Siddique said: "An HGV travelling behind the deceased collided with the rear of her car, crushing the vehicle into the rear of the lorry in front. She sustained fatal injuries."
He said the cause of death was given as multiple bone and soft tissue injury due to a fatal road traffic accident.
The inquest has been adjourned until October 5 to allow the police to conduct their investigation.
Ms Kavanagh graduated 18 months ago as a children's nurse and worked at Walsall Healthcare NHS Trust's school health service. She had been due to start a masters degree.
West Midlands Police is continuing to appeal for anyone who witnessed the collision or has dashcam footage to contact the Serious Collision Investigation Unit.
Nobody else was injured in the incident, which closed the motorway for nearly nine hours as the scene was cleared and investigators examined the road.
West Midlands Police said both lorry drivers stopped at the scene and are helping officers with their inquiries.
An air ambulance, paramedics and firefighters were all sent to the scene following a 999 call at 8.52am.

A GoFundMe fundraising appeal set up by Ms Kavanagh's friend, Rebecca Lockley, to help her family with the cost of her funeral, has almost hit its target of £2,750.
