8 Things to Do the Day of Your Car Accident:

Most people know to exchange information after being in an accident, but there are many other critical steps to take. Here are our suggestions on what to do the day of your car accident:

  1. Call the police immediately, even if you do not think you are injured. The police report will help identify liability for your case.
  2. Never admit fault – let your lawyer figure that out for you.
  3. Do not move your vehicle until you have taken photos of the property damage and surrounding area. Remember to include photos of the license plate of the other cars involved.
  4. Get the name, address, phone number and insurance information of the other driver.
  5. Go to the local emergency room or urgent care and be examined by a medical professional right away.
  6. Notify your insurance company asap
  7. Start your no-fault claim**.
      a. No-fault can reimburse you for lost wages and medical expenses.
  8. Stay away from social media and call us so we can start your investigation

Truck and Semi-Truck Accident Statistics:
Because of their heavy weight and massive size, pickup trucks and semis can cause critical injuries and even long-term disability if victims of truck accidents suffer extensive neurological damage. The U.S. Department of Transportation reports that nearly 97 percent of accidents involving larger trucks or semi-trucks result in fatalities. With 15 percent of trucks on U.S. highways and interstates representing big rigs, tractor trailers, and 18-wheelers, drivers of small and medium-sized cars are at risk of suffering injuries and vehicle damages if involved in a catastrophic accident with a truck. The DOT also states that more than two deaths and 60 injuries occur for every one hundred million miles driven by a semi-truck or big rig. Nearly 140,000 people are injured in truck crashes each year in the U.S. Fortunately, the car injury attorneys at William Mattar have the knowledge and experience to seek maximum compensation for those suffering serious physical injuries caused by negligent or reckless truck drivers.
