Darla Renee Jackson, 25, was heading north on Interstate 5 in Chula Vista when she got angry with an active duty Navy service member riding a red Ducati two-wheeler near her Nissan Altima about 5:30 p.m. Thursday, according to the California Highway Patrol.
The rolling altercation continued as the two passed through National City and merged onto eastbound State Route 54, CHP public affairs Officer Jake Sanchez said.
Just west of the Highland Avenue off-ramp, Jackson allegedly rammed the motorcycle from behind and then ran over the 39-year-old rider.
The victim's name was withheld pending family notification.
The reason for the roadway dispute was unclear.
Jackson was booked into Las Colinas women's jail in Santee and was being held without bail pending arraignment, scheduled for Tuesday afternoon.
Jackson's mother, Margie, disputes the allegations. She says her daughter, who is 24 and the mother of a three year old, is being wrongly accused.
"The motorcycle was trying to cut through some cars and for whatever reason he kicked the side of my daughter's car," said Margie, who did not provide a last name.
Margie went on to say her daughter took off after the motorcycle to get the driver to pull over.
"She went on to follow him trying to get information for the insurance and what have you," said Margie.
Authorities asked any witnesses to the crash or what led up to it to call CHP traffic investigator Brad Clinkscales at 619-220-5492.
