The passenger on the moped was also taken to the hospital, but the prosecutor's office did not release any information on their injuries.
The driver of the dump truck remained on the scene and is cooperating with investigators, authorities said. No charges or fines have been issued.
Dedham police and the Norfolk DA's office are investigating the crash. They have not said if the snow and icy conditions contributed to the crash.
