A WA race car driver accused of killing two motorists and injuring two others in a head-on crash in the US has been granted more freedom under new bail conditions imposed by a Californian judge but will now be required to wear an ankle monitoring bracelet. Luke Nardini, 31, is accused of driving a white BMW on the wrong side of the road near La Honda, south of San Francisco, last year, before crashing head-on into a Ford Taurus carrying four people. Mr Nardini again faced the San Mateo County court on Wednesday morning WA time when Judge Donald J. Ayoob granted a motion by Mr Nardini’s lawyers to ease his travel restrictions. A speedway racer from a well-known Narrogin family, Mr Nardini is charged with two counts of misdemeanour manslaughter for a fatal head-on collision in the mountain community of La Honda on September 1. The crash occurred after Mr Nardini allegedly crossed into the wrong driving lane because of road construction, and collided with another vehicle. The back-seat passengers in the Ford SUV, Jack and Linda Davis, a local couple in their 80s, died from their injuries. Speed and alcohol are not believed to have been a factor in the accident. Mr Nardini was arrested and later released from jail after posting $US20,000 bail. As part of his release agreement, he had to surrender his passport and remain in San Mateo County. At the pre-trial hearing on Wednesday, Mr Nardini’s lawyer May Mar argued the 31-year-old had met all the “requirements of his bail release and was not a flight risk”. However, the San Mateo County District Attorney’s Office objected to the defence’s motion. “We do not believe Mr Nardini has significant ties to California, and should not be granted a supervised release,” San Mateo County’s District Attorney Steve Wagstaffe told The West Australian in an interview. Judge Ayoob sided with Mr Nardini and rejected the prosecution’s objection. Mr Nardini will now be allowed to travel to the nine counties that make up the San Francisco Bay area. However, as a condition of the supervised recognisance release, Mr Nardini will have to wear a monitoring bracelet. In addition to the criminal case, Mr Nardini is also facing two civil lawsuits that have been filed against him by the families of the victims. He is expected to return to a San Mateo County courtroom for a pre-trial hearing on April 2.
