Loading Long stuff in Trucks
 

How far can I have things hanging out the back of my truck(red flagged of course) before I run into problems?

Assuming a pickup truck with only one rear axle, 4m from the axle to the end of the load.

Also consider that you need a light, not just a flag if operating at night.

So 6' beyond the tailgate or bumper? I can live with that.
