A man threatened a teenage driver with a shotgun after she mistakenly drove with her headlights on high beam in the NSW Hunter Valley.
The 17-year-old girl was unaware she had her headlights on high beam as she was driving on Aberglasslyn Rd, Rutherford, about 10.20pm (AEDT) on Saturday.
Police say the ute driver in front of her changed lanes and began following her car, before they both pulled over to the side of the road.
"It's alleged he exchanged words with her two passengers, produced a firearm and pointed it at each of the occupants, repeatedly sliding the pump-action loader," police said in a statement.
The man then drove off and police were called to the scene.
Officers later arrested an 18-year-old man at a home in Avery St, Rutherford, and charged him with offences including using an offensive weapon with intent to commit an indictable offence.
He is due to appear in Maitland Local Court on March 1.
Meanwhile, a Sydney man has been charged with possessing a prohibited firearm after allegedly terrorising motorists with a replica rifle in the city's inner west.
A woman called police after she spotted a man swinging a firearm and pointing it at drivers on the Princes Highway at St Peters about 5pm on Sunday.
Police later arrested a 23-year-old man they saw walking along King St, near the intersection of Darley St in Newtown.
They allege he was carrying a rifle that appeared to be a replica.
The man was granted bail to appear at Newtown Local Court on February 23.
