Cody Hall was also passing another vehicle in a two-way left-turn lane and across double yellow lines, those documents say.
When Hall -- who police said was driving a 2004 silver Dodge Neon -- attempted to pull back into his lane, he lost control.
"Hall's vehicle continued northbound out of control, subsequently colliding with two bicyclists traveling northbound in the east bike lane of Foothill Road," according to a probable cause declaration filed with the court. "As a result of the collision with the two bicyclists, one bicyclist was severely injured and the other bicyclist was fatally injured."
The young driver, who graduated from Foothill High in June, was charged July 26 with vehicular manslaughter with gross negligence and reckless driving with serious injury. He was released on $100,000 bail.
Hall made his first court appearance Monday, where bail was continued. He was also ordered not to get behind the wheel.
"I would like it ordered that he not drive," prosecutor Jim Meehan asked Judge Hugh Walker.
"I was going to do that anyway," Walker said, telling Hall that should he be caught driving, he'd be held in Santa Rita Jail without bail.
Hall did not enter a plea Monday. His next appearance has been set for Aug. 14.
Diana Hersevoort, 58, of Dublin was killed in the June 9 crash near Golden Eagle Way that occurred around 1 p.m. A police report from the crash said Hersevoort was thrown from her bicycle and pronounced dead at the scene.
Her husband Joe was taken to a hospital where he was treated for injuries and released with a broken leg.
The bicycle ride was a weekly tradition of the couple, who rode together in various parts of the Tri-Valley region, their daughter, Heather Grimm said in an earlier interview. They had been together for 35 years.
Grimm confirmed that her family is pursuing a civil case against Hall, but said she'd been instructed not to comment on the case.
Hall stopped at the scene and initially was cooperative with police, answering questions. He did not give a statement when asked.
The teen faces up to six years in state prison if convicted of the vehicular manslaughter charge and between 30 days and six months in jail for the reckless driving charge, along with a fine of between $220 and $1,000. In the criminal complaint filed against Hall, prosecutor Eileen McAndrew said he would not be eligible for a lesser sentence -- a year in county jail -- on the manslaughter charge.
The teen's father was arrested after police served a search warrant at the Halls' home, looking for evidence as part of their investigation into the crash.
Aaron Hall, 43, pleaded not guilty last week to felony weapons charges after police said they discovered two illegal assault rifles and "thousands of rounds of ammunition" in a gun safe at the Halls' home in the 4200 block of Echo Court.
The elder Hall was charged with possession of a firearm by a convicted felon, possession of an assault weapon, possession of ammunition by a felon, and possession of a non-narcotic controlled substance. Police said they found four Daytrana patches, a stimulant used to treat ADHD that Aaron Hall had without a prescription.
Aaron Hall turned himself in July 13. He was released the same day after posting a bond of $265,000.
Court records show he had two felony convictions from 1994 for assault with a deadly weapon and firing at an inhabited dwelling. A pretrial hearing on Aaron Hall's new charges has been set for Aug. 28.
