U.S. Car Accident Statistics: How Many Crashes Happen Each Year?

There are approximately 13 million car accidents in the United States every year, according to the National Safety Council (NSC). An estimated 39,000 people were killed in auto crashes in 2022, and another 2.6 million people visited emergency departments for crash-related injuries. Researchers have determined that 90% of auto crashes are caused by human error.

Key U.S. Car Accident Statistics at a Glance

  • 13 million car accidents occur in the U.S. each year (NSC).
  • 39,000 people were killed in auto crashes in 2022.
  • 2.6 million people visited emergency departments for crash injuries.
  • 90% of auto crashes are caused by human error.
  • 8 teen deaths per day result from motor vehicle crashes (NHTSA).
  • Motorcyclists accounted for 16.2% of all traffic fatalities in 2024.

How Dangerous Is Driving for Teens?

The National Highway Traffic Safety Administration (NHTSA) estimates there are eight teen deaths (ages 13 to 19) per day in the U.S. from motor vehicle crashes. Crashes involving young drivers remain the number one cause of preventable death for U.S. teens.

How Many Traffic Deaths Involve Motorcyclists?

In 2024, motorcyclists accounted for 16.2% of all traffic fatalities and 3.6% of all traffic injuries — a disproportionate share given how few vehicles on the road are motorcycles.

How Do Wrongful Death Claims Work in Alabama?

Alabama law is unique when it comes to wrongful death claims. Most other jurisdictions compensate family members based on the “economic” value of the lost life. Alabama takes a different approach: it holds that all lives are precious, so damages are assessed based on the degree of the wrongdoing that took the life — not the economic value of the life that was taken.

Three other rules distinguish Alabama wrongful death claims:

  • Who can file: Wrongful death claims are prosecuted by the personal representative of the deceased (or the parents of a minor child).
  • Who receives the proceeds: Wrongful death proceeds pass to the heirs of the decedent under Alabama Code §43-8-41.
  • Creditor protection: The proceeds are not subject to the claims of the decedent’s creditors.

What Should You Know Before Hiring a Car Accident Attorney?

Alabama law places very limited regulations on attorney advertising. This means lawyers can make all kinds of claims about money they’ve recovered for car accident victims. Many of these commercials carry nearly microscopic disclaimers such as “Not an actual case,” “Dramatization: Not an Actual Case,” or “Not a Typical or Expected Result.” The attorney featured in the commercial is often not the lawyer who will handle your case — much of the work is done by case managers, paralegals, and associates.

Here is what to look for before you sign with a firm:

  • Free consultations: All personal injury attorneys provide free consultations. Whether or not you think you’ll need an attorney, anyone with an injury claim should consult an experienced auto-crash injury attorney as soon as possible after an accident. Always meet or speak with the attorney who will actually handle your file before hiring — do not rely solely on the opinions of an intake specialist, case manager, or paralegal. An early consultation can also tell you when it may become beneficial to hire an attorney for your claim.
  • Contingency fees: Personal injury attorneys work on a contingency fee arrangement — a fee is only paid if the attorney successfully recovers money for you. You should receive a copy of any fee agreement you sign, along with copies of other claim-related documents. Be wary of firms that charge “administrative” or “document” fees.
  • The “settlement mill” approach: Many high-volume firms operate as settlement mills, focused on settling cases quickly to maintain cash flow for advertising. That can mean accepting lower settlement offers rather than spending the time and resources to maximize your compensation.
  • Willingness to go to trial: While most claims settle before or during the lawsuit process, a few cases must be tried before a jury to maximize the settlement value for the injured victim. Before hiring a lawyer, make sure he or she has courtroom experience.
  • Personal attention: Many high-volume firms do not provide individualized attention. Their business model prioritizes case volume over the unique details and complexities that can drive up the value of your claim. Don’t be treated as just a number — be a top priority.

How Many Accidents Are Caused by Semi-Trucks?

In 2024, approximately 120,724 large trucks were involved in crashes resulting in an injury in the U.S. — a 5.4% increase from 2023. That same year, large trucks accounted for 9% of all vehicles involved in fatal crashes. Since 2016, the number of trucks involved in injury crashes has increased 18% (National Safety Council: 2024 Data).

Semi-Truck Accident Statistics at a Glance

  • 120,724 large trucks were involved in injury crashes in 2024.
  • 5.4% increase in truck injury crashes from 2023 to 2024.
  • 9% of all vehicles involved in fatal crashes in 2024 were large trucks.
  • 18% increase in trucks involved in injury crashes since 2016.
  • 70% of people killed in large-truck crashes in 2024 were occupants of the other, smaller vehicle.
  • Semi-trucks can weigh up to 80,000 pounds — roughly 20 times a typical passenger car.

What Are the Most Common Causes of Semi-Truck Accidents?

When the semi-truck driver caused the accident and is the at-fault party, negligence usually stems from the size, weight, and operational demands of the vehicle. According to FMCSA’s Large Truck Crash Causation Study, the most frequent causes include:

  • Driver fatigue: Long hours behind the wheel or skipped rest breaks can lead a driver to nod off or lose focus — often tied to violations of federal Hours of Service (HOS) rules.
  • Distracted driving: Cell phone use, GPS adjustments, or eating behind the wheel pulls a driver’s attention away from a vehicle that requires far more reaction time than a passenger car.
  • Improper loading: Cargo that is overloaded or not properly secured can shift mid-drive, throwing off the truck’s balance and causing a rollover or loss of control.
  • Speeding and aggressive driving: Because semi-trucks need significantly more distance to stop, driving too fast for road or weather conditions dramatically raises the risk of a rear-end or jackknife collision.
  • Equipment failure: Skipped maintenance can lead to blown tires, failed brakes, or malfunctioning lights — all especially dangerous given the size of the vehicle.

Why Are Semi-Truck Accidents So Deadly?

Because semi-trucks can weigh up to 80,000 pounds, accidents involving them are significantly more devastating than typical passenger-car collisions. In 2024, 70% of the people who died in crashes involving large trucks were occupants of the other, smaller vehicle — not occupants of the truck itself (National Safety Council: 2024 Data).
