Did you see my Tues 2/27 accident? (Colton)

Hi … Did you see an accident on Tues 2/27 @ 3:55pm in Colton? A dark colored 18-wheeler on westbound Valley Blvd was stopped at the red light on Mt Vernon.
There is a 7-11 convenience store & gas station at that intersection.
My elderly mom was behind him in her grey 2016 VW Tiguan.
When the light turned green, the big truck went into reverse and hit my mom’s front end.
Crazy! She got out to exchange information but he turned right, heading north on Mt Vernon.
She didn’t get any info on the truck.
She can’t easily afford the repairs so I’m hoping someone saw what happened and remembers the business name of the 18-wheeler truck that hit her.
It’s a long shot, but I’m crossing my fingers that you’ll help us out.
:-) Please email me thru the Craigslist link in the corner or text me @ show contact info Thanks!
