The driver involved in the fatal crash that killed Engadine man Drew Cullen has faced trial this week.
Albert Cvetkovski, 44, was charged with dangerous driving occasioning death, negligent driving, causing bodily harm by misconduct in charge of a motor vehicle and driving a vehicle with illicit drugs present in blood over the crash in August 2015.
Mr Cullen, 39, an off-duty Fire and Rescue NSW officer, died at the scene when the utility he was driving was crushed by a truck as he was driving across a narrow bridge on Heathcote Road at Heathcote on August 11.
He was returning home after doing a landscaping job at Beverly Hills for a friend when the accident occurred.
During a trial in the Downing Centre District Court this week Mr Cvetkovski defence argument was that he was driving across the bridge when he hit a pothole and that caused the steering wheel to bounce.
He then clipped the car going in the opposition direction.
However the prosecution said blood taken from Mr Cvetkovski after the incident showed low-levels of methamphetamine in his system.
The trial before Judge Penelope Hock continues.
