A black Renault Megane collided with a number of people in the Newry Road area of the city shortly before 10pm on Monday.
The vehicle then fled the scene.
Three men, who were hit by the car, sustained injuries that are not believed to be life-threatening.
The teenager was arrested a short time later in the Cavancaw Road area.
He is currently assisting police with their inquiries.
A number of people had been protesting in the area at the time following the decision to restrict the flying of the Union Flag outside Belfast City Hall.
Earlier, the Cuchulainn Bar on Thomas Street had its windows smashed and fireworks were thrown inside at around 9pm.
Local Sinn Féin Councillor Roy McCartney said: "These very easily could have set fire to the bar or injured those inside.
"The protests, intimidation and violence needs to end and Unionist politicians need to be to the fore, using whatever influence they have, in ensuring this happens."
SDLP Armagh Councillor Thomas O'Hanlon appealed for calm in the city following the incidents.
"There was a protest on the main Newry Road at the top of the city mall and it caused much disruption to many local people trying to go about their daily business," Cllr O'Hanlon said.
"The key issue needs to be respect. Everyone needs to remember that."
Police have appealed for witnesses of both incidents to contact them.
