Sussex Police said that the force had set up a dedicated contact point as the investigation continues.
The force said: “A teenager was seriously injured after being hit by a truck opposite the Ladies Mile pub in Warmdene Avenue at about 8.47pm on Saturday 7 October.
“A vehicle described as a black Ford Ranger pick-up truck, with a double cab and an open back, is reported to have run over the pedestrian before turning around and going over him again as his body lay on the floor.
“It then made off from the scene east on Mackie Avenue.
“The victim, a 19-year-old local man, had been walking home with friends when the incident occurred.
“He was taken to Royal Sussex County Hospital in Brighton where he remains in a serious but stable condition.
