Here comes the bride into the cop car.

While en route to the altar Monday, Amber Young, 32, was arrested for reportedly causing a three-car crash in Marana, Arizona, according to police.

Authorities said they detained the bride — who was wedding-ready in her floor-length white gown — on suspicion of driving under the influence.

The pre-nuptials crash sent one person to the hospital with minor injuries, police said.

Officers apprehended Young at the scene and later released her after she submitted to a blood test, Tuscon News Now reported.

“Don’t drive impaired. Till death do we part doesn’t need any help,” Marana Police Sgt. Chriswell Scott tweeted.
