Maria de Villota is conscious and undergoing further medical assessment at Addenbrooke's Hospital in Cambridge, England, following her crash of a Marussia F1 car in during testing.
The Marussia Formula 1 test driver was rushed to the hospital earlier in the day following an accident shortly after her first run for the team at a straightline aerodynamic test at nearby Duxford Airfield. According to eyewitness reports, after slowing down as she prepared to return to the temporary pit awning, de Villota's car lurched toward the rear of a team transporter, and collided with a tail-lift at the rear of the truck.
Emergency services were called immediately and, after being extracted from the car, she was transferred with what the ambulance service called "life-threatening injuries" to the hospital, where she arrived in a stable condition.
Marussia issued a statement on Tuesday afternoon indicating that her life was not in danger, but saying that it was too early to assess the extent of her injuries.
"Since Maria's arrival at the hospital this morning, she has been receiving the best medical attention possible at the hospital, which is the region's major trauma center," the team stated. "Maria is conscious and medical assessments are ongoing. The team will await the outcome of these assessments before providing further comment. The team's first priority at this time is Maria and her family."
The F1 community has expressed its best wishes to de Villota, daughter of former F1 driver Emilio de Villota. The 32-year-old Spaniard is a former World Touring Car Championship and Superleague Formula driver, although her only previous experience of grand prix machinery came when she tested a 2009 Renault last year.
Fernando Alonso wrote on Twitter: "I just got home and found out [about] Maria's accident, we called the family and hopefully we will know more soon! All my energy with you!"
