WISCONSIN — Winter weather can often lead to dangerous road conditions.

The Wisconsin Department of Transportation said winter weather contributed to more than 15,000 crashes that killed 38 people in Wisconsin last season, and noted wintry conditions can make it harder to stop a vehicle in snow, sleet and ice.

A winter storm system will move through the state beginning Wednesday night into Friday and early Saturday, which is expected to bring snow, high winds, reduced visibility and frigid temperatures across the state.

Because road conditions will vary, WisDOT is encouraging drivers to be weather aware, especially if traveling for the holiday weekend.

Travel may not be advised in some parts of the state on Friday because of potential blizzard conditions. 

The National Weather Service forecasts strong winds and blowing snow Thursday night through Friday night across most of the state. Wind gusts are expected to get up to 55 miles per hour and could create possible blizzard conditions, limiting visibility on the roads even when snow is not falling.

Sustained winds can make driving difficult, especially for high​-profile vehicles like trucks, which are at risk of losing control or tipping over in windy conditions.

Conditions may become too challenging for tow companies to assist stranded or disabled vehicles, so it could take longer to get help. With subzero windchills expected, becoming stranded on the highway could turn dangerous for motorists.

Additionally, state law requires drivers to travel at speeds that are reasonable and prudent for current conditions. Many winter crashes and slide offs are caused by drivers going too fast in hazardous conditions.

WisDOT also noted it is important for drivers to remember snowplow safety. When approaching a snowplow that’s clearing ice or snow, or laying salt or sand, state law requires drivers to stay at least:

• 200 feet back on a highway with a speed limit of more than 35 miles per hour
• 75 feet back on a road with a slower speed limit

Per WisDOT, road conditions ahead of a plow are likely worse, so drivers should use extra caution if passing a snowplow. Plow drivers have limited visibility and the vehicles often create a cloud of snow that can obscure visibility for all.

Additionally, drivers should always be prepared on every trip behind the wheel. If possible, stay off the roads during severe winter weather and wait until conditions improve. WisDOT said staying home eliminates the risk of a crash and helps keep the roads clear for first responders and snowplow drivers.

WisDOT and the Wisconsin State Patrol recommend the following winter driving tips:

• Check 511wi.gov for road conditions or incidents along your route
• Clear snow and ice from vehicles before traveling
• Fill the gas tank and windshield washer fluid
• Allow extra travel time, following distance, and reduce your speed during winter conditions
• Avoid using cruise control in winter conditions
• Have a fully charged phone and an emergency kit in your vehicle
• If you get stranded or slide off the road, stay buckled up in your vehicle and call 911 for help
• Be cautious on bridges, overpasses and entrance and exit ramps
