What happens when you don't clear the snow off the top of your vehicle

According to the Schoharie County Sheriff's Office, snow and ice from the uncleared roof of a U-Haul truck severely injured a 50-year-old woman in Middleburgh yesterday. 

A press release states that Gloria Spiers was driving south on State Route 30 as 30-year-old Katie Rovario was driving north in the U-Haul when ice and snow from the top of the U-Haul struck Spiers' windshield.

Spiers sustained "serious head and facial injury" and was transported to Albany Medical Center, the press release states.
