Michigan's legal minimum bodily injury and property damage (BI/PD) limits are $50,000 per person / $100,000 per accident / $10,000 property damage — written as 50/100/10. The 2020 reform also introduced a 250/500/10 default that most carriers use as their standard starting point. Farmers Insurance offers limits up to 500/500/500 on a standard auto policy without needing an umbrella. But here's the uncomfortable truth: for many drivers, the minimum is nowhere near enough — and a single serious accident can wipe out years of savings if your limits are too low.
What Is Bodily Injury Liability?
BI covers injuries you cause to other people in an accident. If you're at fault and the other driver (or their passengers) are hurt, your BI pays for their medical bills, lost wages, pain and suffering, and legal costs — up to your policy limit. Once that limit is exhausted, you're personally on the hook for the rest. That means your wages can be garnished, your savings seized, and in extreme cases, your home equity targeted.
What Are the BI/PD Options With Farmers?
Farmers Insurance offers a range of bodily injury and property damage limits. Common choices include:
- 50/100/10 — Michigan's legal minimum
- 250/500/10 — the common default most carriers start with
- 250/500/50 — minimum BI with better property damage
- 500/500/50 — higher per-person protection
- 500/1,000,000/100 — strong protection for most families
- 500/500/500 — maximum standard auto limits with Farmers Insurance (no umbrella required)
- $1M+ umbrella — for total liability above $500K. See our umbrella insurance guide.
Why the Minimum Is Often Too Low
A Single Serious Injury Can Exceed $250K
A bad crash can easily generate $300K, $500K, or more in medical costs, lost income, and pain-and-suffering claims. If you carry 250/500, the first $250K is covered — but anything above that comes out of your pocket. A jury doesn't care what your insurance limit is; they award damages based on actual harm.
You Have Assets to Protect
If you own a home, have retirement savings, or earn a solid income, you're a litigation target. Plaintiffs' attorneys check your assets before deciding whether to pursue a case beyond your insurance limits. Low BI coverage invites them to go after your personal assets.
Umbrella Insurance Depends on Strong Base Limits
If you want a $1M+ umbrella policy (and you should if you own a home), most carriers require minimum underlying BI limits of 250/500 or 500/1M. If your auto BI is too low, you can't get the umbrella — or the umbrella won't cover the gap.
How to Choose the Right BI Limit
Rule 1: Match Your Net Worth
A rough guide: your total liability coverage (auto BI + home liability + umbrella) should equal or exceed your net worth. If your net worth is $400K, 250/500 auto + $500K home liability + $1M umbrella = $1.75M total. That's solid protection.
Rule 2: Consider Your Future Earnings
Even if your net worth is modest today, a court can garnish your wages for years. If you're a young professional with high earning potential, higher BI limits protect your future income.
Rule 3: Factor in Household Risk
Households with teen drivers, long commutes on busy highways (US-131, I-96), or frequent out-of-state travel face higher accident exposure. Higher BI limits are cheap insurance against that risk.
What Property Damage (PD) Should You Carry?
The third number — property damage — covers damage to other people's vehicles and property. Michigan's minimum is $10,000. That's shockingly low:
- A single new SUV or pickup can cost $40K-$70K to replace
- Hitting a commercial vehicle or building can easily exceed $10K
- Multi-car pile-ups on Michigan winter roads can destroy several vehicles
Most Knight Family Agency clients carry at least $50,000 or $100,000 in property damage. The premium increase from $10K to $50K PD is usually only $20-$40 per year — a no-brainer.
The Real Cost of Higher BI Limits
Here's the good news: going from 250/500/10 to 500/1M/100 doesn't double your premium. In most cases, the increase is $100-$300 per year — less than a dollar a day for dramatically better protection. If you bundle with home insurance and use discounts like the Farmers Signal app, that increase shrinks even further.
