Serious car crashes happen every day, and many involve occupants who are minors. Motor vehicle crashes are the leading cause of injury-related death for children between 5 and 19 years old, according to the CDC.If your child was involved in any accident whatsoever, take them immediately to the nearest emergency department (ER). Children are less able to communicate their symptoms, so they could have an injury even if they claim they are not hurt.Medical tests and diagnostics are critical for establishing that an injury occurred after an accident, reducing the chances that you will have a contestable injury claim.
