Max Out Your Uninsured and Underinsured Motorist Coverage on Your Dirt Bike — Here's Why
By Josh Cotner
The Call That Changes Everything
Marcus was three miles into a Sunday trail ride outside Phoenix when it happened. A rider on a borrowed bike came bombing around a blind corner, crossed the center line, and hit Marcus head-on. He remembers the impact. He remembers the helicopter. He does not remember the two weeks in the ICU, but the bills tell the story — $218,000 in medical expenses, $34,000 in follow-up rehab, and a modified dirt bike that was totaled.
The other rider had insurance. Minimum limits. Arizona requires $25,000 per person in bodily injury liability. That is the maximum his carrier paid. Twenty-five thousand dollars against a quarter-million in actual damages. The rest was on Marcus.
His health insurance picked up a portion, but after deductibles, copays, and out-of-network charges for the trauma surgeon, he was still staring at $47,000 in uncovered medical costs plus $12,000 for his destroyed bike. He was not at fault. He did nothing wrong. And he was nearly sixty grand in the hole because someone else carried the cheapest legal insurance available.
That is the scenario maxed-out uninsured and underinsured motorist coverage exists to prevent. Here is why it matters more for dirt bike riders than almost anyone else on the road.
What UM and UIM Actually Are — In Plain Language
Most riders hear "uninsured motorist" and assume it only matters if the other person has zero insurance. That is half the story. There are two separate coverages, and you need to understand both.
Uninsured Motorist Coverage (UM) pays your medical bills, lost wages, and pain and suffering when the at-fault party has no insurance at all. They are completely bare. Nothing. You are on your own unless you carry UM.
Underinsured Motorist Coverage (UIM) pays when the at-fault party has insurance but their limits are too low to cover your actual damages. This is the far more common scenario. They have the state minimum — $15,000 in some states, $25,000 in others — and your bills are five or ten times that. Their insurance company writes you a check for the limit and walks away. UIM kicks in for everything above their limit, up to your UIM limit.
These are almost always bundled together as UM/UIM on your policy. You select a limit — $50,000, $100,000, $300,000 — and that is the maximum your own insurance will pay per person when someone else does not have enough. In most states, you cannot carry a UIM limit higher than your own bodily injury liability limit, so if you carry $100,000/$300,000 in liability, that is the ceiling for your UIM as well.
This is the coverage that pays when someone else's mistake becomes your financial problem.
Why Dirt Bike Accidents Are a Different Beast
Dirt bike crashes are not fender benders. There is no crumple zone, no airbag, no seatbelt. You are exposed — helmet, boots, gloves, and hope. The injury severity in off-road motorcycle accidents is consistently higher than in on-road passenger vehicle accidents for several reasons:
Higher speeds in uncontrolled environments. Motocross tracks, trail systems, and open desert riding all involve high-speed riding in areas with no traffic controls, no lane markings, and no predictable traffic patterns. Another rider can appear from any direction at any time.
No protective vehicle structure. In a car accident, the vehicle absorbs the impact. In a dirt bike accident, your body absorbs it. Broken collarbones, shattered wrists, traumatic brain injuries, spinal injuries, and internal organ damage are common even at moderate speeds.
Unpredictable terrain. Rocks, ruts, drop-offs, sand, mud, water crossings — the riding surface itself is a hazard. An accident caused by terrain is one thing. An accident caused by another rider on unpredictable terrain is worse, because now you are dealing with another person's liability on top of everything else.
More uninsured and underinsured riders than you think. The dirt bike community skews younger. Many riders are on their parents' policies, on borrowed bikes, or riding without any coverage at all. Even when another rider has insurance, it is often the cheapest possible policy — minimum liability, no additional coverage. A 17-year-old on a borrowed CRF250R is not carrying $300,000 in liability limits.
Off-road liability complications. When an accident happens on private property, a track, or an unmarked trail, determining liability is messier than a street accident. Property owners may have limited or no liability coverage. Other riders may not have coverage that extends to off-road use. The legal landscape after a dirt bike accident is far less clean than after a car accident, which means you need to be prepared to cover your own damages even when someone else is clearly at fault.
Road-legal situations are the wild card. If your dirt bike is street-legal — dual sport, plated enduro — you ride on public roads to access trails. That means you are sharing space with cars, trucks, and drivers who may or may not have insurance. One in eight drivers nationwide is uninsured. In some states, it is closer to one in five. If an uninsured driver T-bones you on the paved road to your favorite trailhead, UM is the only thing standing between you and financial ruin.
State Minimum Liability Limits — The Top 10 Dirt Bike States
Here are the current state minimum bodily injury liability limits for the ten states with the most registered dirt bikes and off-highway vehicles. These are the maximum amounts the other guy's insurance will pay per person if they carry only minimum coverage:
| State | Per-Person Bodily Injury Limit | Per-Accident Bodily Injury Limit |
|-------|-------------------------------|----------------------------------| | California | $15,000 | $30,000 | | Texas | $30,000 | $60,000 | | Florida | $10,000 | $20,000 | | Arizona | $25,000 | $50,000 | | Colorado | $25,000 | $50,000 | | Pennsylvania | $15,000 | $30,000 | | Michigan | $50,000 | $100,000 | | Ohio | $25,000 | $50,000 | | Georgia | $25,000 | $50,000 | | North Carolina | $30,000 | $60,000 |Florida: $10,000 per person. That is the lowest in the country. A single ambulance ride, ER visit, and CT scan can approach $10,000 before any treatment even begins. If you are riding in Florida and someone with minimum limits causes an accident that puts you in the hospital, their insurance covers roughly the cost of your initial intake — nothing more.
California: $15,000 per person. The most populous state for off-road riding has one of the lowest minimum limits in the nation. A broken femur with surgery and a three-day hospital stay runs $50,000 to $75,000. California's minimum covers less than one-third of that.
The average across all ten states: roughly $25,000 per person. That number is dangerously low for any accident involving serious injury.
The Math: What Actually Happens in a Real Accident
Let us run the numbers on a realistic scenario. A moderate-to-serious dirt bike accident — not a fatality, not a scraped knee, but something that puts you in the hospital for real.
The accident: Another rider clips you at speed on a trail. You go down hard. Broken collarbone, broken wrist, concussion, three days in the hospital, surgery on the wrist, six weeks of physical therapy.
Total medical bills: $200,000
That is not an inflated number. Emergency room visits average $2,200 to $3,300. Surgery with anesthesia runs $15,000 to $50,000 depending on the procedure. A three-day hospital stay with imaging, medication, and specialist consultations easily hits $30,000 to $50,000. Follow-up physical therapy at $150 to $350 per session for six weeks adds $5,000 to $15,000. Lost wages during recovery could add another $10,000 to $30,000.
Scenario A: The other rider has minimum limits (Arizona — $25,000)
| Damage | Amount |
|--------|--------| | Medical bills | $200,000 | | Other rider's insurance pays | $25,000 | | Your out-of-pocket | $175,000 |Your UM/UIM coverage kicks in for the $175,000 gap — but only up to your limit.
- With $50,000 UM/UIM: You are still $125,000 short. Bankruptcy territory.
- With $100,000 UM/UIM: You are still $75,000 short. Devastating.
- With $250,000 UM/UIM: Fully covered. You walk away whole.
- With $300,000 UM/UIM: Fully covered with room to spare.
| Damage | Amount |
|--------|--------| | Medical bills | $200,000 | | Other rider's insurance pays | $0 | | Your UM coverage pays (at $100,000) | $100,000 | | Your out-of-pocket | $100,000 |Even with $100,000 in UM coverage, you are still on the hook for half the bill. At $300,000 UM, you are covered completely.
Scenario C: The other rider has minimum limits AND you have health insurance
Your health insurance covers a portion, but health insurance is not a free ride:
| Item | Amount |
|------|--------| | Medical bills | $200,000 | | Other rider's liability pays | $25,000 | | Health insurance deductible (average HDHP) | $3,500 | | Health insurance out-of-pocket maximum | $8,700 | | Health insurance covers | $162,800 | | You still pay | $12,200 |Better — but that assumes your health insurance works perfectly, covers every provider as in-network, and does not deny any claims related to an off-road motorcycle accident. Some health insurance policies exclude injuries from recreational off-road riding. Read your policy.
Also, your health insurance company has subrogation rights. That means they can pursue the at-fault rider for reimbursement — and any money they recover comes out of what would otherwise go to you. If the at-fault rider has no assets, the health insurance company gets whatever they can squeeze out of minimum limits, and you are still paying your deductible and out-of-pocket maximum.
Health insurance is a safety net. UM/UIM is the coverage specifically designed for this exact situation. They serve different purposes, and having both is not redundant — it is smart.
How Much Does Maxing Out UM/UIM Actually Cost?
This is where most riders stop. They hear "increase your limits" and assume the cost is prohibitive. It is not.
UM/UIM coverage is remarkably cheap relative to the protection it provides. Here is what upgrading looks like on a typical dirt bike insurance policy:
| UM/UIM Limit | Estimated Annual Cost | Monthly |
|-------------|----------------------|---------| | State minimum (matches liability) | Often included at no extra cost | $0 | | $50,000/$100,000 | $30 to $60/year | $2.50 to $5 | | $100,000/$300,000 | $50 to $100/year | $4 to $8 | | $250,000/$500,000 | $80 to $150/year | $7 to $12.50 | | $500,000 CSL | $120 to $200/year | $10 to $17 |These are estimates for a typical recreational dirt bike rider. Actual rates depend on your state, riding history, bike value, and carrier. But the pattern holds across virtually every situation: UM/UIM is one of the cheapest per-dollar coverages you can buy.
Think about it this way. The difference between $50,000 UM/UIM and $300,000 UM/UIM might cost you an extra $40 to $60 per year. That is the cost of a single set of grips and a couple of tubes. For that $60, you are buying $250,000 in additional protection — protection that pays when someone else's insurance walks away after a crash they caused.
Every objection to maxing out UM/UIM falls apart under scrutiny.
Addressing the Common Objections
"It costs too much"
We just covered this. The jump from minimum UM/UIM to maximum limits typically costs less than a set of tires per year. If you can afford to ride, you can afford this coverage. And you absolutely cannot afford the alternative — a six-figure medical bill with no way to pay it.
"I only ride alone on private property"
If you never ride with anyone else and never ride on or near public roads, your exposure to other parties is certainly lower. But "only" is a strong word. Most riders eventually ride with friends, attend group rides, participate in organized events, or transit on public roads to reach their riding spot. The moment another person is involved, UM/UIM becomes relevant. And if your bike is street-legal and you ride on any public road for any reason — even the paved access road to a trailhead — you are sharing space with uninsured drivers. One in eight of them has no insurance.
"My health insurance covers everything"
Partially true, with major caveats. Your health insurance likely covers medical bills — after your deductible and out-of-pocket maximum. But health insurance does not cover lost wages, pain and suffering, or damage to your bike and gear. UM/UIM covers all of those. Additionally, some health insurance policies exclude injuries sustained during off-road recreational riding, especially if you were on an unmarked trail or private riding area. Check your policy's exclusions before assuming you are covered.
"I already have high liability limits"
Having high liability limits is great — it protects other people if you cause an accident. But your liability limits protect them, not you. UM/UIM protects you when someone else causes an accident and does not have enough coverage. These are completely different coverages serving completely different purposes. You need both.
"The other rider can be sued personally"
Sure, in theory. In practice, suing an individual rider who carries state minimum insurance is like squeezing blood from a rock. If they could only afford minimum coverage, they likely do not have $175,000 in accessible assets to cover a judgment. You win the lawsuit, they declare bankruptcy or simply cannot pay, and you are still holding the bag. Insurance exists because personal assets are unreliable. Maxed-out UM/UIM is the coverage version of that principle.
"I have an umbrella policy"
Umbrella policies provide additional liability protection, but they typically sit above your auto and motorcycle liability limits — they protect others from your mistakes, not the reverse. Some umbrella policies include UM/UIM coverage, but not all, and the terms vary. If you have an umbrella, check whether it includes UM/UIM and whether it stacks with your dirt bike policy. Do not assume.
How to Actually Get Maximum UM/UIM Limits
This is where working with an independent agency matters. Captive agents — the kind who work for one company — can only offer that company's products and limits. If their UM/UIM maximum is $100,000, that is all you get.
An independent agency like ours shops multiple carriers. Some carriers offer UM/UIM limits up to $500,000 combined single limit. Others offer stacking options, where the UM/UIM limit on each insured vehicle adds together for a higher total. Every carrier structures this differently, and the difference between carriers can mean hundreds of thousands of dollars in additional protection at roughly the same price.
Steps to maximize your UM/UIM:
1. Request UM/UIM quotes at your maximum available limit. In most states, this means matching or stacking up to your bodily injury liability limit. If you carry $250,000/$500,000 in liability, you can typically carry the same in UM/UIM.
2. Compare across multiple carriers. The same $300,000 UM/UIM limit can cost $60 per year with one carrier and $120 with another. An independent agent finds the better rate. 3. Ask about stacking. In some states, if you insure multiple bikes on one policy, the UM/UIM limits stack — meaning two bikes at $100,000 UM/UIM each gives you $200,000 in total coverage. This is state-dependent and carrier-dependent. 4. Do not waive UM/UIM in writing. Some states allow insurance companies to include a waiver form that reduces or eliminates your UM/UIM coverage in exchange for a lower premium. Never sign this. The savings are negligible and the risk is catastrophic. 5. Review your limits annually. As medical costs rise — and they do, every single year — the coverage that was adequate five years ago may not be adequate today.The Bottom Line
Dirt bike riding is higher risk than driving a car. The medical costs from a serious accident are higher, the likelihood that the other party has minimal insurance is higher, and the financial consequences of being underinsured are severe. Maxing out your UM/UIM coverage is not about being paranoid. It is about being realistic.
For an extra $50 to $100 per year — the cost of a tank of gas and a six-pack of energy drinks — you can carry $300,000 or more in coverage that pays when someone else's insurance does not. That is not a luxury. For anyone who rides seriously, it is the most important coverage decision on the policy.
Get a quote that includes maximum UM/UIM limits. Compare what multiple carriers charge for that coverage. And ride knowing that if someone else's mistake puts you in the hospital, you are covered — not just partially, but completely.
