The Massachusetts Department of Transportation has released surveillance footage of two teen riding on the back of a truck.
The incident occurred last Tuesday during rush hour on Interstate 93 near Chinatown.
Stunned motorists tried to alert the truck driver of the unwanted passengers.
Eventually, motorists were able to get the truck driver to stop, but as soon as he did, the teens jumped off the truck and dashed away.
The teens have not been identified.
