A Jersey City, NJ, police lieutenant on the job for 23 years was killed on the New Jersey Turnpike early this morning.

Christopher Robateau, 49, of Carteret, exited his car to help a motorist on his way to work this morning and was struck by a vehicle, according to Mayor Steve Fulop.

"We consider him on duty being that Lt. Robateau got out of his car to help someone else which is what we want all our officers to be doing all the time regardless of their location or time of day," Fulop said on Facebook.

Robateau leaves behind a wife and three children, NJ.com reports.
