A Western Australian man accused of killing two motorists in a head-on collision in the US has been released on bail.
Narrogin man Luke Nardini, 31, was driving a BMW M4 on Highway 84 near San Francisco in California on September 1 when he collided with another car on a tight blind turn.
One man and one woman were killed, while two others were hospitalised.
Nardini was charged over the crash.
Nardini posted a $US20,000 ($31,000) bail and had to surrender his passport.
The matter returns to court in October.
