A7, near his home in Byåsen, Trondheim, while driving under the influence (DUI) of alcohol. At the time, it was suspected that the car was driving well over the speed limit, which was at the site of the crash. A 23-year-old male passenger broke his collar bone in the crash. After the crash, Northug fled the scene, but was located at his nearby residence by the police using search dogs. In a press release made later the day of the crash, Northug apologised for the incident. On 15 September 2014, Northug was charged by the Norwegian public prosecutor with five counts of violation of the Norwegian Road Traffic Act and one count of violation of the general civil penal code. The latter charge stemmed from Northug having claimed, in three separate police interrogations on the day of the crash, that his passenger had actually been driving the vehicle at the time of the accident. Due to Northug's initial claims, the passenger had been preliminarily charged with causing the incident. Because Northug pleaded guilty to all the charges leveled against him, he received a summary trial, which took place on 9 October 2014 at the Sør-Trøndelag District Court in Trondheim. Northug was sentenced to 50 days of prison, ten days less than requested by the prosecutor. He had already served two days of the sentence in police custody after his initial arrest. In addition to the prison time, Northug was fined and lost his driver's license [indefinitely, or at least] for five years. The prison sentence was served, while wearing an ankle monitor, in his home. As a result of the crash, Audi decided not to renew their sponsorship agreement with Northug. Audi had been a sponsor of Northug since June 2011. 2020 On 13 August 2020, in Ullensaker, Northug was caught going on a road in his Jaguar F-Type SVR.

A later indictment in 2020 charged him with reckless driving at high speed, illegal possession (in his home) of 6 grams cocaine, 0.6 grams of MDMA, three tablets containing Diazepam and two tablets containing Alprazolam; and [holding or] using a mobile phone while driving. He pleaded guilty (before trial) on all counts; in a summary trial on 21 December 2020 he testified
