Motorcycle liability insurance covers the costs you owe to other people when you cause an accident. It pays for the other driver’s medical bills, lost income, and property repairs, but it does not cover your own injuries or damage to your bike. Almost every state requires riders to carry liability coverage, making it the foundation of any motorcycle insurance policy.
The Two Parts of Liability Coverage
Motorcycle liability insurance has two distinct components: bodily injury liability and property damage liability. They work together but cover different types of losses.
Bodily injury liability pays for the other person’s medical expenses, rehabilitation costs, lost wages, and pain and suffering when you’re at fault in an accident. If someone you hit needs surgery, physical therapy, or time off work, this portion of your policy covers those costs up to your policy limit. It also covers legal defense costs if the injured person sues you.
Property damage liability pays to repair or replace the other person’s property. That usually means their vehicle, but it can also include fences, guardrails, mailboxes, or anything else you damage in the crash. If you slide into a parked car or knock over a utility pole, property damage liability handles the bill.
How Coverage Limits Work
Liability limits are expressed as three numbers separated by slashes, such as 25/50/25. Each number represents a cap, stated in thousands of dollars:
- First number: The maximum the policy will pay for one person’s bodily injuries (in this example, $25,000).
- Second number: The maximum the policy will pay for all bodily injuries combined in a single accident ($50,000).
- Third number: The maximum for property damage ($25,000).
So a 25/50/25 policy would pay up to $25,000 for any one injured person, no more than $50,000 total if multiple people are hurt, and up to $25,000 for property damage. If the costs exceed those limits, you’re personally responsible for the difference. That’s why many riders choose limits well above their state’s minimum.
State Minimum Requirements
Every state sets its own minimum liability limits for motorcycles, and they vary widely. On the low end, some states require as little as 15/30/5, meaning just $5,000 in property damage coverage and $15,000 per person for injuries. On the higher end, a few states start at 50/100/25. The most common minimum across states is 25/50/25.
These minimums are exactly that: the legal floor. A single trip to the emergency room can easily exceed $25,000, and a serious accident involving multiple vehicles or long-term injuries can produce bills in the hundreds of thousands. Carrying only the state minimum leaves you exposed to out-of-pocket costs if a claim goes beyond your limits. Increasing your coverage from the minimum to something like 100/300/50 typically adds a modest amount to your premium relative to the protection it provides.
Guest Passenger Liability
If you ride with a passenger and cause an accident, your passenger may also have a claim against you for their injuries. Guest passenger liability is a form of bodily injury coverage that specifically protects passengers on your motorcycle. Some states include it automatically as part of your standard liability policy. In states where it isn’t mandatory, you can usually add it as a separate endorsement for a small additional cost.
Like all liability coverage, guest passenger liability only applies when you’re at fault. It pays for your passenger’s medical bills and related expenses, not your own. If you regularly carry a passenger, confirming this coverage is on your policy is worth a quick call to your insurer.
What Liability Insurance Does Not Cover
Liability insurance is entirely outward-facing. It protects the people and property you harm, not you or your motorcycle. That means several important gaps exist if liability coverage is all you carry:
- Your own injuries: If you’re hurt in a crash you caused, liability won’t pay your medical bills. You’d need medical payments coverage (sometimes called MedPay) or personal injury protection to fill that gap.
- Damage to your motorcycle: Repairs or replacement for your own bike require collision coverage (for crashes) or comprehensive coverage (for theft, vandalism, weather, and other non-collision events).
- Accidents caused by someone else: If another driver hits you and they’re uninsured or underinsured, your liability policy won’t help. Uninsured/underinsured motorist coverage handles that scenario.
Riders who finance or lease a motorcycle will typically be required by the lender to carry collision and comprehensive coverage on top of liability. Even if you own your bike outright, these additional coverages can save you from paying thousands out of pocket after a theft or a crash that totals your motorcycle.
Choosing the Right Liability Limits
Start by looking at what you’d owe in a worst-case scenario. Motorcycle accidents tend to produce more severe injuries than car accidents because riders and other parties are more exposed to impact. A single accident involving hospitalization, surgery, or long-term disability can easily generate six-figure claims.
Consider your personal assets when selecting limits. If a judgment exceeds your coverage, courts can go after savings, investments, and even future wages. Higher liability limits cost relatively little compared to the financial exposure they eliminate. Many insurers recommend at least 100/300/100 for riders who want meaningful protection. If you have significant assets, an umbrella policy that sits on top of your motorcycle liability can extend your coverage into the millions for a relatively low annual premium.
