Suing a government driver: sovereign immunity and notice deadlines

You can sue a government employee's driving only because a statute lets you, and the statute sets conditions: a written claim to the right office within a deadline that is often far shorter than the ordinary limitation period, a cap on what can be paid in many states, and no punitive damages. The conditions are enforced strictly, so a driver with a strong case can lose it by missing a notice date or filing against the wrong party. The first step after a crash with a bus, police car or postal truck is to find out who owns the vehicle and which notice rule applies, not to wait for an insurer's offer.

This article is the legal background. It explains sovereign immunity and its waivers, compares the federal process with examples from Florida, Texas, California and New York, covers the immunities for emergency driving and police pursuits, and lists the mistakes that forfeit claims. For the practical sequence after a collision, including evidence to collect and how to use your own coverage while you wait, see accidents with a city, state or federal vehicle. Rules differ by state and change; the dates and amounts here are as of November 2026 and are a starting point for a conversation with a licensed attorney, not a substitute for one.

Why a government cannot simply be sued

Sovereign immunity is the doctrine that a government cannot be sued without its consent. It comes from the English idea that the Crown could do no wrong and survives in the United States as a rule that the government must agree to be a defendant. Every state and the federal government have agreed, through statutes called tort claims acts, to be sued for some kinds of negligence, including negligent driving by employees. Those statutes are called waivers of immunity.

A waiver has three consequences for a driver who was hit:

1. The statute defines the claim. If the crash does not fit the waiver, there is no claim. Texas's waiver, for example, covers property damage, personal injury and death caused by an employee's negligence if it arises from the operation or use of a motor-driven vehicle and the employee would be personally liable under Texas law (Tex. Civ. Prac. & Rem. Code 101.021). California's vehicle code provides that a public entity is liable for death or injury proximately caused by a negligent or wrongful act or omission in the operation of a motor vehicle by an employee acting within the scope of employment (Cal. Veh. Code 17001).
2. The statute sets the procedure. Presenting a claim, naming the right body and waiting for a response are conditions of suing.
3. The statute sets the remedy. Many waivers cap damages, bar punitive damages and shut out interest before judgment.

The same standard of fault generally applies as with a private driver: the government is liable for negligence by an employee acting within the scope of the job. Federal law puts it as "in the same manner and to the same extent as a private individual under like circumstances," with no interest before judgment and no punitive damages (28 U.S.C. 2674).

The federal route: the Federal Tort Claims Act

A claim for a crash caused by a federal employee driving in the course of the job goes through the Federal Tort Claims Act (FTCA), which sits in Title 28 of the United States Code. The core rules:

• Who counts. An employee of the government includes officers and employees of any federal agency and military personnel, but the definition of federal agency "does not include any contractor with the United States" (28 U.S.C. 2671). If a private contractor employee was driving a delivery vehicle for a federal agency, the FTCA process may not apply, and an ordinary lawsuit against the contractor and its insurer may be the route. For service members, scope of employment means acting in line of duty.
• Administrative claim first. A suit cannot start unless the claim was first presented to the appropriate federal agency and finally denied in writing, sent by certified or registered mail. If the agency has not made a final disposition within six months after the claim was filed, the claimant may treat that as a denial (28 U.S.C. 2675(a)).
• Two years to present, six months to sue. A tort claim against the United States is "forever barred" unless presented in writing to the agency within two years after it accrues, or unless the lawsuit is begun within six months after the date of mailing of the notice of final denial (28 U.S.C. 2401(b)). In practice that means two deadlines: one to present the claim and one to file suit after a denial.
• What counts as presenting. A claim is deemed presented when the agency receives an executed Standard Form 95 or other written notice of the incident, together with a claim for money damages in a sum certain, and evidence of the signer's authority if the signer is an agent (28 CFR 14.2). The government publishes the form as SF95, Claim for Damage, Injury, or Death. A claim goes to the agency whose activities gave rise to it, and a wrongly addressed claim should be transferred to the right one, though the date of receipt by the appropriate agency controls under the regulation.
• The number on the form matters. A lawsuit generally cannot seek more than the amount of the administrative claim, unless the increase is based on newly discovered evidence not reasonably discoverable when the claim was presented or on intervening facts (28 U.S.C. 2675(b)). Claimants whose injuries are still developing should ask a lawyer how to state the sum.
• Settlement authority. An agency head may settle claims administratively; amounts over $25,000 need the Attorney General's approval unless that authority has been delegated (28 U.S.C. 2672).
• No jury, no punitive damages. Actions under the FTCA are tried by the court without a jury, with narrow exceptions (28 U.S.C. 2402), and the United States is not liable for punitive damages or prejudgment interest.
• Attorney fees are capped. A lawyer may not charge more than 25 percent of a judgment or a settlement made after suit, or more than 20 percent of an administrative award, compromise or settlement (28 U.S.C. 2678).
• The driver usually cannot be sued personally. If the employee was acting within the scope of employment, the remedy against the United States is exclusive of any other civil action for money damages against the employee (28 U.S.C. 2679). The employee's scope of employment therefore becomes a central question. If the driver was off duty, there may be no FTCA claim, and the claim may belong against the driver and their personal auto insurer.

The FTCA also lists exceptions. One of them bars claims based on the exercise or failure to exercise a discretionary function or duty (28 U.S.C. 2680(a)). Whether it reaches a particular driving claim depends on the facts, and it is one reason an agency's denial may be contested.

State and local claims: the same pattern, different numbers

States copy the structure of the federal act but set their own periods and limits. The table gives four examples. These are not a complete list and they change, so confirm the current text.

Texas's cap applies to each unit of government, so which kind of entity owns the vehicle changes the number. A city bus, a county sheriff's car and a state highway truck sit in three different rows.

A worked comparison

Say the same collision happens in four places. A government vehicle hits Maria's car on March 3, she is badly hurt, and her total damages come to $400,000. The numbers are hypothetical.

• Florida, city bus. Her damages exceed the statutory limit, so the most she can collect through the normal process is $200,000. The $200,000 above the limit may be reported to the Legislature, which can pay it in part or in whole only by further act. The statute allows the entity to settle within its insurance coverage without further legislative action.
• Texas, city vehicle. The cap for a municipality is $250,000 per person for bodily injury, so about $150,000 of her damages is beyond what the statute allows against the city.
• California, county vehicle. The sources checked did not show a general damage cap, but her claim must reach the county within six months, and a rejection starts a six-month suit clock.
• New York, village vehicle. She has 90 days to serve a notice of claim, and the lawsuit must be started within one year and 90 days of the crash.

The point is not that one state is generous. It is that the identical injury produces different deadlines and different maximum recoveries, and the person who calls her own insurer first and a lawyer six months later may find the notice date has already passed.

Emergency driving and pursuits

A large share of government driving claims involve emergency vehicles, and many states soften liability for them.

• Texas excludes from its tort claims act a claim arising from an employee's action while responding to an emergency call or reacting to an emergency situation, if the action complies with the laws and ordinances applicable to emergency action or, absent such a law, is not taken with conscious indifference or reckless disregard for the safety of others (Tex. Civ. Prac. & Rem. Code 101.055).
• New York's traffic law gives drivers of authorized emergency vehicles certain privileges, but the statute says the privileges do not protect the driver from the consequences of reckless disregard for the safety of others (Veh. & Traf. Law 1104(e)). The legal standard in an emergency-vehicle case is therefore higher than ordinary negligence.
• California provides that a public employee is not liable for civil damages from operating an authorized emergency vehicle in the line of duty while responding to an emergency call or in immediate pursuit of an actual or suspected violator (Veh. Code 17004). A separate section gives a public agency immunity for harm from a collision involving the vehicle of a suspect being pursued by its officers if the agency has adopted a written pursuit policy that meets statutory standards and provides annual training (Veh. Code 17004.7).

The result is that a bystander hit by a fleeing suspect, or by a police car running to a call, may face an immunity defense that a bus-rear-end case would not. Whether the immunity applies depends on the facts and on the version of the law in your state, which is one reason these claims are usually handled by lawyers.

Choosing whom to sue

Government cases often involve a choice between suing the entity and suing the employee. The statutes push the claimant toward the entity.

• Federal: the remedy against the United States is exclusive when the employee acted within the scope of employment.
• Texas: under the election-of-remedies section, filing suit against the governmental unit "constitutes an irrevocable election" that bars a suit against any individual employee on the same subject matter, and suing an employee bars suit against the governmental unit unless it consents. If both are sued, the employees are dismissed on the unit's motion (Tex. Civ. Prac. & Rem. Code 101.106).
• Florida: an officer or employee may not be held personally liable in tort for acts within the scope of employment unless the employee acted in bad faith, with malicious purpose, or in a manner exhibiting wanton and willful disregard of human rights, safety or property (Fla. Stat. 768.28(9)(a)).

A mistaken choice, for example suing the driver personally in Texas, can end the claim against the government.

How insurance fits in

Governments rarely buy a policy that looks like yours. Many are self-insured or pool risk with other public bodies, and the claim is handled by a risk-management office, a claims administrator or the attorney general's office. Florida's statute recognizes this: the state or an agency may agree, within the limits of insurance coverage provided, to settle a claim without further legislative action, but obtaining insurance does not waive sovereign immunity or raise the limits.

Your own policy matters in three ways:

1. Collision and medical payments coverage. Your collision coverage and medical payments coverage pay regardless of who was at fault, which lets you repair the car and treat injuries while a government claim moves slowly. Your insurer may then pursue the government through subrogation, and you may need to claim your deductible.
2. Uninsured motorist coverage may not apply. The standard ISO personal auto policy form says that an "uninsured motor vehicle" does not include a vehicle "owned by any governmental unit or agency" (PropertyCasualty360's analysis of the ISO form, 2018). That is one common form, not every insurer's, and state law may treat the exclusion differently, so ask your insurer in writing. See uninsured and underinsured motorist coverage explained.
3. Keep the insurer informed. Your policy may require prompt notice and cooperation, and your insurer's subrogation rights can be affected by a settlement you sign.

Mistakes that forfeit claims

1. Waiting for the other side to call. The notice clock starts at the crash in most states, not when the agency denies fault.
2. Calling the wrong office. The city clerk, county clerk, state claims office and federal agency are different offices. Send the notice to the one the statute names.
3. Treating a phone call or email as notice. Statutes ask for a written claim containing specific contents, and under the federal rule receipt by the agency controls.
4. Leaving out a sum certain. A federal claim needs a dollar amount, and it can cap a later lawsuit.
5. Suing the wrong defendant. In some states, suing the employee can bar suit against the government, or the reverse.
6. Ignoring a short local deadline. A city charter may set a shorter period than the state statute, as Texas law expressly allows.
7. Missing the second deadline. After a denial, a short suit window starts, such as six months in the federal system and in California.
8. Signing a release too early. A release for property damage or a medical payment can be written broadly.
9. Assuming a late notice will be excused. Courts in some states can allow late notice, as New York's statute does in a court's discretion, but the standards are narrow and the application has its own limits.

Questions to ask in the first call

• Who owns and who employs the driver of the vehicle? Is it a federal, state, local or special-district body, or a private contractor?
• What is the written-claim deadline for this body, and who must receive the claim?
• Does the statute cap damages, and does the cap apply per person or per incident?
• Was the driver responding to an emergency or in a pursuit?
• Is there a form, and must it state a dollar amount?
• Has a claims administrator or insurer been assigned, and what is its mailing address for notices?

Common questions

Can I sue the driver instead of the agency?

In the federal system, usually not, because the remedy against the United States is exclusive when the employee acted within the scope of employment. In Texas, the election-of-remedies rule can bar you from suing the employee once you sue the unit, and the reverse. Florida limits personal liability to bad-faith or malicious conduct. Ask a lawyer before choosing.

Is the claim deadline the same as the statute of limitations?

Not usually. The notice or presentment deadline is a separate, shorter deadline to give the government written notice, and a limitation period for filing suit follows. The ordinary periods for private defendants are in statutes of limitations for car accident claims.

Can I get punitive damages from a government?

The federal act and the Texas and Florida statutes quoted above exclude them. Other states have their own rules.

Does my insurer handle the claim for me?

Your insurer can pay your own collision or medical coverage and may pursue the government, but it does not file your personal injury claim or protect your notice deadline. For help with that, see when to hire a lawyer after a car accident.

Key takeaways

• Sovereign immunity means a government can be sued only under a statute, and the statute's notice, deadline and damage rules are conditions of the claim.
• The federal process requires a written claim, usually on Standard Form 95 with a sum certain, within two years, and a lawsuit within six months after a denial.
• State and local deadlines range from 90 days to 3 years, damage caps vary by entity, and punitive damages are generally unavailable under the statutes reviewed here.
• Emergency driving and police pursuits can raise the standard of proof or create immunity, so those cases need early legal advice.
• Your own collision, medical payments and uninsured motorist coverage may help in the interim, but the standard ISO personal auto form excludes government-owned vehicles from its uninsured motor vehicle definition, so ask your insurer how your policy treats them.
