Michigan’s Deadliest Roads and Fatal Accident Statistics

MoneyGeek analyzed 2,820 fatal crashes on Michigan’s roadways between 2018 and 2020 to find the deadliest stretches of road in the state. In Michigan, there are 256,579 miles of road; we included 1,742 roads in our study.

MoneyGeek’s study also examined what factors contributed to fatal accidents across the state and shed light on how drunk driving, speeding, distracted driving, winter driving and time of the year played a role in these fatal accidents. Additionally, we summarized county-specific data, including the deadliest roads in each area.

• SR-3 Gratiot Avenue from Liberal Street to Van Dyke Avenue is the deadliest stretch of road in Michigan. Between 2018 and 2020, 16 fatal accidents occurred here.
• A total of 28.5% of fatal accidents were related to drunk driving. These accounted for 803 of the 2,820 total fatal accidents in the state.
• Just 4.8% of Michigan’s deadly crashes involved winter weather conditions, despite the state ranking as MoneyGeek’s deadliest state for winter driving.
• Speeding contributed to 25.9% of accidents, or 729 fatal accidents, between 2018 and 2020. Within the same time period, distracted driving contributed to 6.3% of crashes, or 179 fatal accidents.
• August had the most fatal accidents (331) between 2018 and 2020. This month was followed by July (301) and September (289).
• Wayne County had the highest number of deadly crashes (539) of any county. The deadliest road within the county was 1-94: 24 fatal accidents occurred on that stretch of road.

Between 2018 and 2020, 803 of the 2,820 total fatal accidents in Michigan involved drunk driving. Drunk driving far outweighs fatal accidents related to distracted driving, speeding and winter weather, making it the most common factor involved in fatal accidents in Michigan.

It’s easy to underestimate the effects of alcohol. While a blood alcohol concentration (BAC) of 0.8% marks you as legally intoxicated in Michigan, even a BAC of 0.2% can impair your vision and make it harder to perform two tasks simultaneously. This small amount of alcohol may diminish your driving abilities and make you and others more vulnerable on the road.

Whether or not drunk driving results in a fatal crash, the costs of a DUI are severe and long-lasting, possibly resulting in suspension of your license, restrictions on your driving privileges or jail time. Being convicted of a DUI will make it much harder to find affordable auto insurance in Michigan. This is because you will be required to obtain Michigan SR-22 insurance, which is often more costly than traditional policies.

In the three years between 2018 and 2020, speeding caused 729 fatal accidents in Michigan, accounting for 25.9% of all fatal accidents. It is the second-leading cause of deadly accidents in the state.

When you speed, you jeopardize yourself and others. Driving too fast, whether in suburban areas or on highways, can make it difficult to stop when needed, increasing your risk of causing a crash.

Of the factors we measured, the third-leading contributing factor to fatal car accidents in Michigan is driving while distracted. Distracted driving was involved in 179 deadly crashes in Michigan between 2018 and 2020, or 6.3% of all fatal accidents. Based on MoneyGeek's analysis of the worst states for distracted driving, Michigan ranked better than 66% of states.

In Michigan, the month of August had the highest number of fatal accidents between 2018 and 2020, accounting for 11.7% of all fatal accidents. A total of 331 accidents occurred in August.

Following this is July, during which 10.7% of accidents occurred, or 301 fatal crashes. September ranked third, with 289 or 10.2% of fatal accidents. Based on these statistics, more accidents seem to happen in Michigan when the climate is warmer. This phenomenon is somewhat surprising, considering that Michigan ranked as the most dangerous state for winter driving.

Safety is crucial to your well-being and that of other drivers. In addition, it can help you save money in the long run. Unfortunately, accidents cannot always be avoided. Therefore, we recommend getting an affordable full coverage auto insurance policy to better protect you and your family.

The average cost of auto insurance in Michigan is $4,333 per year. The actual cost will, however, vary by county and even city. For instance, the average cost of auto insurance in Detroit is $5,471, while car insurance in Grand Rapids costs an average of $1,738 per year. This is a difference of a whopping $3,733.

It should be noted that while MoneyGeek collected premiums across Michigan, these figures are simply averages. To get the most affordable auto insurance for your requirements, consider comparing quotes from other providers. Providers will determine your premiums based on a wide range of factors, including your age, driving record and ZIP code, among others.
