Hi fellow riders, I need your help and suggestion about lane filtering and change lane during the red light. Accident Description: All of the event described was during the red light (the light doesnt change to green or amber when the accident happen). I am a full licensed rider in NSW, Sydney and was filtering the lane (my speed was less than 15 km/h) in the middle of 2 lanes and about to change the lane between 2 cars (turning left between the car in front and on my rear), I turned my signal on and when I was 1/4 way to change the lane, and then the car on my rear lightly accelerated and hit the back of my vespa. It was a small scratch on my vespa and on the car (not a big accident), but the car owner lodged to the insurance company and they deemed I was at fault because I change the lane dangerously. I am confident that I am not at fault as the light was still red when I change the lane (with a good buffer of approximately another 30 seconds before the light change green), I turned my signal on and there is an ample space between these cars for me to change lane. At the moment, the insurance company stated that I am responsible but I rejected and want to appeal. And now the Debt Collection Agency is asking for the accident description and diagram about this. At the moment, I am not sure what to write in the accident description and diagram as I feel that the Insurance Company or the Collection Agent would be subjective on this matter. What do you think guys? Any help or suggestion is appreciated.
