Safe riding - rider down outside my house

[Gone in 60]

Found a video taken by someone standing on the street as the police and rescue crews did their investigation. From the position of the downed bike next to the back bumper of the fire truck, the truck had barely started to back into the roadway from the right. Unless the fire truck pulled forward after the impact for some reason, the bike must have been far over to the right hand edge of the roadway against the curb after making the sweeping left turn.

Unlikely that the fire truck moved, however, as the bike would be more in the middle of the road, not immediately next to the truck.
