The man was arrested late yesterday afternoon at his residence on charges of criminal negligence causing death and fail to remain at the scene of an accident.
He is cooperating with police and has been released from custody until charges are formally laid by Crown prosecutors.
Dhillon was killed when he was struck by a silver Honda Accord making a left hand turn at the intersection of 96 Avenue and 123A Street in Surrey.
Witnesses told police the motorcycle was travelling westbound on 96 Avenue when the Honda, which was travelling eastbound, turned left in front of it.
Dhillon, who was from Surrey, was transported to hospital but was later pronounced dead.
Police say the Honda driver kept travelling north on 123A Street for one block before abandoning the vehicle and fleeing on foot.
After the crash attempts to track the driver with a police dog were not successful, but police said documents and registration in the car were being used to trace the driver.
On Wednesday night Dhillon's family and friends held candles and wept at a public vigil for the teen. Many were too emotional to speak including Dhillon's father.
Fellow motorcycle riders also paid their respects. They described Dhillon as a bright, safe and experienced motorcycle rider despite his young age, who was no daredevil — a friendly boy who loved off-roading and dirt bikes.
