Before hitting the road this winter season, Illinois natives know the importance of having a snow-brush.
"The windshields, all the windows, the headlights, license plate usually," said Vicki Moseley of Springfield.
But not everyone clears their car before pulling out for a drive. Deputies at the Sangamon County Sheriff's Office say it is a state law.
"Every person that operates a motor vehicle shall remove snow, ice and other material from their windshields so they have a clear view of the highway," said Lt. Robert Steil.
If you don't follow the rules you could face a $125 fine. You even risk thousands of dollars if the snow comes unhinged, hitting another driver.
"If it does fall off the vehicle, you could be held liable for the damages," said Lt. Steil.
It's a danger Vicki Moseley has seen before.
"I have been behind cars where big chucks of ice come off," said Moseley.
Police also remind drivers it's more than just clearing off your back window and front windshield. You also need to get the tail-lights as well as the license plate or you could face a fine.
No matter how many times drivers are reminded, there are still those few who will hop in the car, risking damage to others.
"It's stupid. They have these little things where they can see out of the windshield. Just clean your windshield off really good. Clean your car off before you start," said Kim Curtis.
Police are also asking drivers this winter to clear snow off the roof as best they can. When it begins to snow piling up, it can become a projectile on the highway.
