The Northern Territory road toll has risen to three following the death of a 23-year-old male in Alice Springs overnight.

Northern Territory Police say a pedestrian was struck by a vehicle which then had a collision with a second vehicle around 10:00pm.

Two other males were trapped in the vehicles and were freed with the help of emergency services. They were conveyed to Alice Springs Hospital with non-life-threatening injuries.

Major Crash Detectives are investigating the incident.

A report will be prepared for the coroner.
