Los Angeles - Paul Walker's family road markers could have caused his car to crash.
The Fast & Furious star passed away in November when the vehicle he was travelling in smashed into a tree and street light and burst into flames in Santa Clarita, California.
His relatives are now considering the possibility the accident was caused by Botts' dots - which are raised, non-reflective plastic bumps that mark out the lanes on roads.
Cause of accident still being investigated
A coroner has concluded the deaths of Paul and his friend Roger Rodas - who was driving the Porsche car when it crashed - were an accident, but investigators are currently looking into the cause of the single-car accident, with speed considered to be a factor.
A source told TMZ: "The family has been in touch with stunt experts, who have gone to the crash site and come back with what they believe is a solid theory - a speeding car that hits the plastic markers will hydroplane, causing the driver to lose control."
Meanwhile, Paul's loved ones, including his 15-year-old daughter Meadow, his parents Cheryl and Paul Walker Sr., his four siblings and his 23-year-old girlfriend of seven years, Jasmine Pilchard-Gosnell, are currently deciding how and when the actor will be laid to rest after his body was released from the Los Angeles County Coroner's Office earlier this week.
The family and friends of the Hollywood star have already held a private memorial at the site of the crash on December 2, but a public memorial service is also being planned for December 15 in Malibu.
