It was shell on wheels.

A woman led authorities on a high-speed chase in Oregon — only for police to discover invasive snails inside the car when they finally caught up with her, police said.

Anastasia Dickey, 33, of Utah, was pulled over Wednesday in Fruitland, Ore., on suspicion of driving under the influence of intoxicants, but allegedly sped off from the scene, the Argus Observer reported.

She led authorities west on Interstate 84 to Ontario, reaching speeds of 92 miles per hour, police said.

The cops attempted to deploy spikes to deflate her tires, but she continued until the vehicle became stranded on Union Pacific railroad tracks, the newspaper reported.

A search of the car turned up “a small amount of meth and in plain view, several snails,” police said.

Dickey was arrested on charges that include reckless driving, attempting to elude a police officer, and driving under the influence, the newspaper reported.

No charges have been filed related to the mollusks though, it’s illegal to bring them from Utah into Oregon under the state’s administrative rules, the newspaper reported.

Josh Vlach, an entomologist with the Department of Agriculture, later confirmed that the confiscated creatures were European brown garden snails and not native to Oregon.

“There are lots of snails we don’t want to come to Oregon,” Vlach told the newspaper.

He said that the snail can be used for escargot dishes or as a garden and crop pest.

The snails are “big and voracious eaters of plants and kind of just about anything,” Vlach said.
