What Is an At-Fault State?

At-fault states (or “tort states”) require the at-fault driver’s insurance company to pay for damages or injuries. To cover these costs, at-fault states require drivers to carry at least liability insurance.

In at-fault states, the driver who caused an accident is financially responsible for it, meaning your insurance company (or you) need to come up with compensation for damages if you cause a wreck.

For this reason, at-fault states (or “tort states”) require drivers to carry liability insurance in minimum amounts. If you’re found responsible for causing the accident, your car insurance will pay for damages and injuries up to your policy limits.

You may need more than the state minimum

The largest group of states requires drivers to carry $25,000/$50,000/$25,000 in liability insurance — that’s $25,000 bodily injury liability per person, $50,000 per accident, and $25,000 property damage liability. However, most drivers, especially in at-fault states, may benefit from higher limits. To ensure all your bases are covered, consider investing in limits of 50/100/50 or 100/300/100. That way, you can be sure that your assets and future finances are well-protected.

The District of Columbia and 38 states have at-fault insurance laws.

No-fault states vs. at-fault states

In no-fault states, car accident victims will contact their own insurance provider — not the at-fault driver’s insurance provider — for bodily injury compensation after a crash. Payment responsibilities in no-fault states fall on the insurance providers of everyone involved, not just the at-fault driver’s provider.

No fault states include: AR, FL, HI, KS, KY*, MD, MA, MI, MN, NJ*, NY, ND, OR, PA*, TX, UT, WA. DE has a no fault aspect to its laws in that it requires all drivers to carry Personal Injury Protection (PIP) coverage. 

* Drivers in these choice-no-fault states may choose no-fault or limited tort coverage.

Compensation is determined by negligence in at-fault states

In the legal sense of the term, negligence describes a failure to take appropriate action resulting in harm to others. This might include things like not seeing a pedestrian in the road, texting and driving, or hitting the gas instead of the brakes.

In a car accident, fault may be determined in percentages, e.g. one driver is 70% at fault while the other driver is 30% at fault, based on how negligent each driver was in the situation.

Once negligence and fault are established, compensation can be determined based on that data.

If you’re at-fault in a collision in an at-fault state: At-fault drivers should follow a similar process after an accident. Don’t admit fault or place blame on the other driver, and try to remain calm both at the scene of the accident and after. This will help you avoid any extra charges being brought against you.

After a car accident in an at-fault state, regardless of fault, your car insurance premiums may also increase. To combat this, it’s a good idea to shop around for a new policy from a new provider. With a car insurance broker like Jerry, this process takes less than a minute.

Understanding your rights in an at-fault state

Drivers who have experienced severe damages due to a negligent driver usually have the right to sue, but it’s best to employ a qualified personal injury lawyer or law firm to help you out.

Things can get extremely complicated when determining who can sue who after an accident. The validity of your personal injury lawsuit will depend on things like state laws, the amount of insurance the other driver was carrying, the amount of insurance you were carrying, and whether your damages passed a verbal (think “catastrophic injuries” or “wrongful death”) and/or economic threshold.
