A driver died in a rollover crash on East Airway Boulevard in Livermore on Saturday afternoon, according to city police.

The Livermore Police Department responded to the intersection of Airway and Rutan Drive just before 2 p.m. Saturday on reports of a serious traffic collision. The driver of a Toyota Yaris lost control of his car and it overturned several times, police said.

Officers arrived to find the driver -- a 39-year-old man from Livermore whose name has not yet been released publicly -- suffering from significant injuries. He was later pronounced dead at the scene, according to police.

Police said they are investigating whether speed and drugs or alcohol were factors in the daytime crash. Toxicology testing results are pending.

The investigation and cleanup at the scene caused the intersection to be closed for more than four hours on Saturday. Police provided updates on the post-crash road closure on Saturday via social media but did not confirm the fatality involved until Monday morning.
