The 3 Collision Rule in Car Accidents

Sep 30, 2021

Car accidents can involve various types of scenarios resulting in injuries. From hit-and-runs to rear-end collisions to multi-car crashes and rolloversmotor vehicle accidents can occur in any number of ways. If you’re injured in a car accident, the first thing that comes to mind is likely not Sir Isaac Newton’s laws of motion.

However, those three distinct laws actually play a significant role in the science of what is known as motor vehicle collision theory. According to Newton’s three laws of motion:

  1. An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
  2. The acceleration of an object depends on the mass of the object and the amount of force applied.
  3. Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first.

Although you may not realize it, these three laws actually play a role in how a car accident impacts each involved object (including the car itself). The driver, the passengers, the physical objects inside, the vehicle itself, and even the internal organs of those involved in a car accident are all affected according to Newton’s laws of motion. As a result, whenever a car accident occurs there are actually three different types of collisions that happen.

Each and every car accident can actually be multiplied by three – as there are three distinct types of collisions that occur within every vehicle. This is commonly referred to as the ‘three collision rule,’ and although it might be a term you’ve heard in the past, it’s commonly misunderstood.

Let’s take a look at what those three types of collisions entail, review what sorts of injuries can occur as a result, and then discuss how to file a personal injury claim with Dordulian Law Group in pursuit of maximum financial compensation for your car accident injury.

What are the Three Types of Collisions That Occur in a Car Accident?

You might be wondering how (or why) to “multiply” each car accident by three. Essentially, this comes down to what’s known as kinetic energy – the energy that is built up in a moving object. When a car accident occurs, one car’s kinetic energy will suddenly transfer to the opposing vehicle or object it strikes. Moreover, every object within that vehicle will also transfer its kinetic energy to the opposing object it strikes. This explains how the three distinct types of accidents occur – as the three potential objects (vehicle, human, internal) involved must transfer their kinetic energy through the force of the crash.

Let’s look at the three types of collisions which occur in every car accident in more detail.

Type One: Vehicular Collision

A vehicular collision is simply one where a vehicle strikes another object. In most cases, this involves one car striking another car in a traditional motor vehicle accident. However, it could also entail a vehicle striking a tree, an animal, a pedestrian, or a piece of property. At the point of impact, the vehicle suddenly decelerates as a result of the force of the collision (according to Newton’s Second Law – that the greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object). In other words, as a vehicle’s weight increases, so does the force of the crash. Additionally, depending on the speed of the crash, the force will likely cause part of the vehicle’s physical frame to be crushed.

Today’s cars are equipped with airbags, reinforced structures, and other safety features designed to help absorb the kinetic energy sustained as a result of a motor vehicle collision. That said, the human body doesn’t have such advanced protections, and is therefore vulnerable to a variety of injuries (which we’ll discuss in greater detail below).

Type Two: Human Collision

The term ‘human collision’ refers to the effect on the occupants inside a vehicle (specifically moving in the same direction and the same speed as the car until contact is made which stops the forward motion). This highlights the importance of seatbelts, as a driver or passenger without a proper restraint will not stop traveling in forward motion until meeting the force of another object (e.g. a steering wheel, windshield, etc.).

While the vehicle’s kinetic energy is diminished through the first type of collision (vehicular), the human body will continue traveling within the vehicle at the same speed and direction as the car until an object causes that forward motion to stop (e.g. a seatbelt/airbag).

In addition to potentially sustaining an injury as a result of striking an object directly, drivers and passengers are at risk of sustaining an injury from a physical item within the vehicle. During a human collision, any physical possession like a phone, camera, water bottle, etc. will continue traveling at the same speed and direction as the vehicle until another object stops that forward motion. In many cases, the driver or passengers are that very object – meaning your cell phone may use your body as a sort of crash pad under Newton’s laws of motion.

Type Three: Internal Collision

Car accident injuries aren’t always physically discernable. In many cases, internal organ injuries can occur as a result of a high-speed or other severe type of car crash. Just like the vehicle and physical objects within it will continue traveling in motion after a crash, so do the internal organs of the driver/passengers. That’s why the third type of collision is known as the internal collision – referring to the internal organs that are still moving in the midst of a car accident.

Even after the body comes to a complete stop, this third type of collision is still in progress. The internal organs keep on moving after the body has officially stopped its forward motion. As a result, the internal organs may not stop moving forward until striking other organs or perhaps even the skeletal system. This is, unfortunately, how a number of serious injuries occur as a result of car accidents.

Given the potential for internal injuries, car accident victims are strongly encouraged to seek medical attention immediately following a crash – even if you feel okay and do not have any visible trauma.

What Types of Injuries Can Occur From the Three Types of Crashes?

Car accident injuries can vary dramatically from person-to-person and crash-to-crash. Let’s review some of the most common injuries resulting from the three types of crashes discussed above.

Vehicle Collision Injuries

  • Back injuries
  • Head injuries
  • Spinal injuries
  • Traumatic brain injury (TBI)
  • Concussion (MTBI)

Human Collision Injuries

  • Facial lacerations
  • Contusions
  • Bruising
  • Collarbone injuries
  • Lower extremity injuries

Internal Collision Injuries

  • Internal bleeding
  • Organ injury
  • Organ failure
  • Broken ribs
  • Ruptured spleen
  • Abdominal pain
  • Abdominal aorta aneurysm

Of course, some injuries within one of the above mentioned categories may actually be sustained by a driver or passenger during a differing type of collision. But these are the most common injuries reported after the three distinct types of motor vehicle crashes under Newton’s laws of motion.

What Types of Damages are Recoverable After a Car Accident?
