Senior Sergeant Anthony Bond, of Dunedin, said a car that crashed into a concrete power pole was discovered by patrolling officers in Malvern St about 1.15am on Sunday.
Investigations revealed the licence plates and registration label had been removed.
However, the warrant of fitness sticker had not been removed from the windshield, allowing officers to track the driver to a nearby address where they discovered an 18-year-old woman who admitted being the driver.
She admitted to officers she had been going too fast and lost control, with one passenger in the car, Snr Sgt Bond said.
Officers were also called to the scene of a crash in Andersons Bay Rd about 11.30am on Sunday where a vehicle allegedly failed to give way while pulling out of the Couplands Bakery car park.
However, the the 19-year-old student who collided with the vehicle recorded a breath alcohol level of 381mcg and was given a court date, Snr Sgt Bond said.
Another crash happened in Cumberland St outside the BP petrol station about 2.45am on Sunday.
Four people ran off and police were working to locate the driver, Snr Sgt Bond said.
At 2.20am that night, officers were called when a 43-year-old man walked out in front of a taxi near the Exchange.
The man was taken to hospital and it was likely he was intoxicated, Snr Sgt Bond said.
A 21-year-old man needed treatment at hospital after he was hit by a car at a party in Dukes Rd, Mosgiel, about 12.45am on Sunday.
The man had stepped off the curb to avoid a fight, Snr Sgt Bond said.
Another collision between two cars happened on 1.45pm Saturday.
An 18-year-old man was driving in Hillside Rd and was waiting for a car ahead of him to turn into a petrol station when he was rear ended by another vehicle.
The man was checked out by a St John ambulance, but was not seriously injured, Snr Sgt Bond said.
On Friday at about 12.30pm, police and other emergency services were called to reports of a collision between a car and a pedestrian in South Rd.
A 77-year-old was driving at the intersection with Eglinton Rd where a 67-year-old man was carrying groceries, which he dropped and bent down to grab.
Unseen by the driver, the man was knocked to the ground.
He was checked over by St John and taken home without injuries, Snr Sgt Bond said.
