A learner driver could face jail time after threatening to kill his examiner and instructor, when he failed halfway through his practical driving test.
Antony Kevin Alltree, 25, also chased his driving instructor Kenneth Spencer down the street whilst shouting expletive language.
Examiner John Williams now locks all his windows and doors as a result of the episode.
He said he has not experienced an episode like this in Nelson for 10 years.
Burnley Magistrates Court heard how Alltree flew into a rage after Williams stopped him entering a roundabout by using the combined breaks, on February 9.
After pulling over to the side of the road, Alltree got out of the car, slammed the door and shouted at Mr Williams: “You would not have one that if you knew who I was.”
Driving Instructor Kenneth Spencer tried to calm Alltree down, yet Alltree shouted: “All I have to do is make one phone call and you are both dead. I will kill you.”
Alter then started banging on the car and continued to shout expletives and when Mr Williams began to drive off towards the test centre, Alltree chased after the car screaming abuse.
Colleagues of Mr Williams rang the police when Alltree arrived back at the test centre.
Once police arrived, Alltree denied ever threatening Mr Spencer and Mr Williams lives.
Defending, Graeme Parkinson said that Alltree suffers from anger management issues and also suffers from ADHD and dyslexia.
Mr Parkinson said his client accepts he had handled the situation badly but chased after the car and went to the test centre to obtain his provisional licence which he was fearful of losing.
"But he said it wasn't until later he realised it had been in his jacket pocket throughout. He said his client did not recall using any expletives but accepts he probably did.
Mr Parkinson said: "He does apologise for his behaviour and he accepts his behaviour was totally unacceptable.”
Alltree has nine previous convictions for offences including assault, disorderly behaviour and dishonesty.
This case in now adjourned until April 25 and Alltree was given unconditional bail.
The chairman of magistrates Mr Creelman said: "We have listened to carefully to what everybody has said and we take on board everything that we have heard, including your condition. This was clearly very shocking for the examiner.
"We are not ruling out any options when it comes to sentencing you."
