Alaska State Troopers say a motorcyclist is dead after slamming into the back of a truck on the Seward Highway Sunday afternoon. 

Troopers spokesperson Megan Peters said just before 1:30, troopers responded to a two-vehicle collision involving a motorcycle near Mile Post 42 of the Seward Highway, near Moose Pass.

Aaron Smith, 44, of Eagle River was traveling southbound on the Seward Highway on a black Harley Davidson motorcycle when he smashed into the back of a truck and was ejected from the bike, according to AST's online dispatch. 

"Smith was following a white 2005 Dodge pickup," troopers wrote.

The Dodge pickup, being driven by a 15-year-old, reportedly braked hard and Smith rear-ended the pickup.

Troopers say Smith was wearing a helmet. [The 15-year-old] reported she was not hurt and was wearing her seatbelt.

"Impairment and speed do not appear to be factors," troopers wrote.

The Highway was temporarily closed for about an hour and a half while troopers investigated.

Update: The name of the Dodge truck driver has been removed from this story after troopers removed it from their original dispatch.
