Dangerous Roads in Wisconsin

Where should you be more aware when driving through the state? There are several key points that result in deadly crashes, and greater care is needed when traversing these stretches of road.

I-94 in Milwaukee

I-94 in Milwaukee near the exits of 305A and 310B caused some of the deadliest crashes. At exit 305A, there is a freeway interchange, and it is believed that this confusing infrastructure may contribute to higher crash rates. Additionally, the highly populated area right off exit 310B, which links to SR-100, increases the likelihood of motor vehicle accidents due to the higher traffic volume.

SR-190 in Milwaukee

Another spot in Milwaukee poses greater dangers for drivers on State Route 190 between the exits that connect to State Route 100 and West Hopkins Street. Both of these spots are busier areas, and higher traffic volume may be factors that lead to more fatal crashes.

US-51 in Madison

In Madison, US-51 between the exits that connect to SR-30 and Anderson Road is a deadly spot. There is an interchange between the two roadways for one and a connection to the airport and college for the other. The increase in fatal accidents in this span is likely due to the interchange, as well as inexperienced younger drivers and those traveling to and from the airport.

I-90 in Janesville

Janesville in Rock County has a deadly span of around 5 miles between exit 171B and 177 as it crosses over SR-14 and SR-26. With an interchange and several large stores off the road, drivers who aren’t paying attention may swerve, while others make poor decisions that cost them their lives.

Factors That Contribute to Wisconsin Accidents

What causes these motor vehicle accidents to happen in Wisconsin? There are a variety of causes behind these tragedies on the road:

Weather

Wisconsin sees its fair share of icy, snowy weather, and drivers need to adjust accordingly to stay safe. Unfortunately, many do not, which leads to an uptick in crashes.

False Sense of Comfort

One of the greatest concerns throughout the state is that Wisconsinites have a false sense of security when they are closer to home. Some may not put their seatbelts on when they’re just running to the corner store or around the corner, and when they do, they’re more likely to suffer severe injuries or fatalities in a crash. Others may buckle up, though, while on the familiar turf of their own neighborhoods, they may zone out and fail to pay proper attention until it’s too late.

Impaired Driving

Drunk driving accidents are a problem across the country. In Wisconsin, many drivers may take on a few too many and then decide that they’ll be fine to get back home since “it’s only a few blocks.” No matter how short the distance is, anyone who has been drinking should never drive.

Time of Day

Night driving sees more accidents than during daylight hours. Experts believe it to be partly due to the lower visibility that comes from the setting sun and darkness. Most accidents happen in the evening and late at night, and while some will involve intoxicated drivers, others may involve drowsy drivers or those who cannot see a hazard until it’s too late.

Hazards on the Road

To that end, many motor vehicle accidents will happen when an animal runs out into the street or onto poorly maintained roads. Potholes can cause a driver to lose control, while a lack of proper lighting and signage at night can make it difficult for even the most responsible of drivers to navigate the roads safely.

How to Reduce Your Risk of a Car Accident in Wisconsin

While some roads have a reputation for being more deadly in certain areas, such as intersections, interchanges, and highways, increase the risk, there are things you can do to protect yourself.

Pay Attention

Driving is a task that requires full and proper focus, and failing to do so could lead to an accident. You should never text while driving, though other seemingly benign actions could also cause you to crash. Looking up directions on GPS, rummaging through your bag, changing your music on the stereo, talking to your passengers, or even munching on a few fries from your takeout meal all have the potential to cause you to take your eyes off the road, your hands off the steering wheel, and your attention from driving safely.

Stay Alert and Sober

Not all drivers who crash are drunk or on drugs. Some may have worked long hours or have other stressors in life that are causing them to lose sleep. If you’re not alert, you should not drive. Drowsy driving can slow your reactions as much as driving while intoxicated, and it’s best to get your rest first before carrying on with the drive. As for getting behind the wheel while intoxicated, there is no excuse with the plentiful rideshare options available. Arrange for a sober ride, and don’t forget that taking prescription medications that your doctor has prescribed to you can cause you to crash if drowsiness is a side effect.

Obey Traffic Laws

Speed limits are posted for a reason, and that’s to keep everyone safe. Speeding, running stop signs or traffic signals, or violating other traffic laws can land you in hot water with the police. You will be more likely to avoid an accident if you abide by the laws. If you are in an accident, you’ll be less likely to be blamed if you were the one obeying traffic laws, too.

Keep Your Car Maintained

Your brakes, tires, and other vehicle features should be maintained. Make sure you keep up with what your vehicle needs. Underinflated tires, as well as overinflated tires, can cause you to lose control, while shoddy brakes will make it impossible to stop in time.

Be Aware of Vulnerable Road Users

Especially in neighborhoods and at intersections, watch for pedestrians and cyclists. They are more difficult to spot, as are motorcyclists. These people may not be paying attention, though you must watch out for them to avoid a collision.

Wear Your Seat Belt

No matter how many years of experience you have behind the wheel or how safely you drive, the negligent actions of others can lead to an accident. You will have a greater chance of survival and a lower likelihood of serious injuries if you remember to buckle up. Don’t let the excuse of “It’s just around the corner” lull you into a false sense of security. A deadly crash can happen even just down the street from your house or on a long road trip. When you secure your seat belt, you’ll be doing your part to protect yourself.

What to Do If You Get into a Wisconsin Car Crash?

Even if you were doing everything right, you may find yourself the victim of motor vehicle accidents in Wisconsin. Calling the police, getting medical care, and taking photos of the aftermath can all help you in the days and weeks that follow. When you go to file an injury claim, make sure you talk to an attorney first to ensure you get the full amount you deserve. Image by Rico Löb; Pixabay
