After a car accident, most people involved can be in a state of shock or experience an adrenaline rush that can make it hard to think. The mental trauma can make it difficult to truly assess the severity of your injuries. It can actually take several days before some symptoms make themselves known. This is one of the reasons why, if you have been in a car accident, it is important to see your doctor as soon as possible for an assessment.
Your teen was with you when it happened. A large semi didn't stop, and you were rear-ended. It was fortunate that no one was in front of you. Your vehicle survived the incident, and you both walked away from the crash with moderate injuries.
If you've ever found yourself driving a vehicle when the tire has blown out then you probably can identify with just how much the operation of your vehicle can quickly become impacted as a result. There's a reason you'll routinely see truckers who have a tire blow out pull over as soon as they possibly can.
