A paparazzo attempting to shoot photos of Justin Bieber's Ferrari was hit by another car and killed this evening -- although Bieber was NOT behind the wheel of the Ferrari ... TMZ has learned.

Law enforcement sources tell TMZ Bieber's white Ferrari was pulled over by California Highway Patrol for speeding on the 405 ... near the Getty Center in LA. The CHP directed the driver to pull off the freeway, onto Sepulveda Blvd.

According to our sources, Bieber was DEFINITELY not driving at the time.

We're told a paparazzo -- who was following the Ferrari at the time of the pull over -- attempted to snap pics while officers conducted the traffic stop.

The photog then crossed Sepulveda to snap pics and was told twice by the CHP to go back to his car on the other side of the road. When the photog tried crossing back, he was struck by an oncoming vehicle as he crossed back and was killed.

Our sources say drugs and alcohol were not a factor for the driver of the vehicle that hit the photog.

LAPD is now on scene investigating the incident.
