Conspiracy theorist Alex Jones was arrested in Texas early Tuesday on charges of driving while intoxicated following a spat with his wife, authorities said.

Travis County Sheriff’s Deputies were responding to a disturbance at Jones’ house in Austin around 10:10 p.m. Monday, when they saw him going 45 mph in a 40 mph zone and stopped him, according to an arrest affidavit obtained by The Post.

“When I made contact with Jones I detected a strong odor of alcohol coming from his person,” the deputy wrote in the affidavit.

Jones, 46, claimed he and his wife got into an argument while eating dinner at a sushi restaurant, where he’d guzzled a bottle of sake, the court document states.

He then said he walked the three miles home from the restaurant, where the couple continued their tiff — prompting him to drive to another residence he owns downtown “to get away from his wife,” according to the affidavit.

Jones’ wife had told dispatchers that the pair got into a physical fight that later turned into a verbal argument.

She said Jones had booked it in a black Dodge Charger and was possibly drinking, the document states.

A sobriety test conducted on Jones found that he had a blood alcohol level of 0.076 at 11:55 p.m. and a level of 0.079 at 11:59 p.m. The legal blood alcohol limit for driving in Texas is 0.08.

However, drivers in the state can be charged with DWI if they’re considered impaired, even if they’re under the limit.

Jones’ eyes were described as watery and glassy with constricted pupils, while his demeanor was listed as excited, talkative, carefree and cooperative, in the documents.

The InfoWars founder was booked into the Travis County Jail around 12:37 a.m., according to Travis County sheriff’s office spokeswoman Kristen Dark.

He was released on $3,000 bond at around 4:11 a.m.

An article on Jones’ InfoWars website claimed he’d only been “drinking a small amount of sake at a Japanese restaurant” and got “caught up in a Travis Co. DWI dragnet.”

Jones is facing several lawsuits from families of children killed in the Sandy Hook massacre for pushing the theory that the mass shooting was a hoax.
