The Blick newspaper said in an online report on Wednesday that the youth had a blood-alcohol level above the legal limit when the accident occurred late Monday night in the municipality of Wernetshausen in the canton of Zurich.
According to police he drove the Suburu four-wheel drive station wagon into the wall of a residence at around 11pm, causing damage estimated at several tens of thousands of francs.
The 64-year-old defence minister's son was driving back to the family home in Hinswil after seeing his girlfriend when the accident occurred, Blick said.
He managed to extricate himself from the wrecked vehicle but when a neighbour offered to call for help from emergency services, he panicked and called out: “No police, no police, I drank,” the daily reported, citing resident Mike Beck, who was at the scene.
It was too late because police officers showed up with the ambulance.
Paramedics put a neck brace on the driver and took him to the hospital where he underwent blood and urine tests, Blick said.
Residents of the village said he was lucky to escape without more serious injuries.
He had only obtained his driver's licence several months earlier, Blick said.
Maurer's son, one of his six children, had a well-publicized brush with the law last year when he ran away from police during a routine check and was subsequently arrested in possession of a small amount of marijuana.
At the time Maurer's communications manager said the matter was a private affair which the minister did not wish to comment on.
