A Casper man has been arrested after colliding with a semi.

Ryan Eidsness was booked under suspicion of DUI.

Investigators say sometime after 2 o'clock Tuesday morning May 15th, Eidness was northbound on Wyoming Boulevard near 15th street, when collided with an oncoming semi.

The driver of the semi said he tried to steer to the shoulder to avoid a head-on collision, but Eidsness still managed to side-swipe the trailer.

Eidsness said that he might have been driving close to the center line when the collision occurred and admitted he had been drinking prior to the crash.
