The incident unfolded after police and other emergency services were called to a two-vehicle crash in South Rd at 4.35pm on Tuesday.
Senior Sergeant Anthony Bond, of Dunedin, said an 18-year-old driver accidentally had his indicator on to turn left, prompting a 40-year-old woman to pull out from Playfair St.
As he continued to drive straight ahead, the woman T-boned the teenager's car, Snr Sgt Bond said.
Nobody was injured in the crash, but while emergency services were at the scene, a black vehicle sped past on the wrong side of the road and pulled into a driveway.
A firefighter went to speak to the 43-year-old driver, who became verbally abusive, Snr Sgt Bond said.
The man followed the firefighter back to the fire truck and attempted to drag him out.
Other firefighters then pulled the man away and he went into a nearby address.
Inquiries are ongoing.
