dump truck on colfax

This dump truck was in traffic ahead of me today on Colfax in Denver and I just had to snap a photo of it with my phone camera.  The writing on the back of the truck says:

u r on vedio [sic]
Do not cut me off
I will sue u after I smash u

And below that message it says:

In Loving Memory Of Mama

Hmmm, I wonder what “Mama” was like?
