Both the conventional and Romanian Deadlifts are great strength and muscle building exercises. Even though they are both deadlifts variations the setup, execution and muscles activated are different.

The Value of Skid Marks for Auto Accident Cases

The Value of Skid Marks for Auto Accident Cases - El Paso Chiropractor


Not only do tires play a vital role in the performance of your car or truck, but a lot of information can be garnered about what happened before, during, and after a crash. Tire marks will be explored by us and, generally, what those marks tell us.



First let us discuss where the marks come from. Skid marks are created by the extreme thermal relationship of a tire against the roadway surface during extreme stresses put on the tire, a simpler way to say this is, a tire will “mark” when it nears, or exceeds, the limits of its relationship with the roadway. These marks occur because the oils in the roadway and/or the tire(s) are brought to the surface and “melted or burnt” into the roadway. If a tire is heated enough since the surface of the tire will have changed, it’ll be obvious, it is going to have a spot and obvious abrasions.



Kinds of Skid Marks.


There are three specific kinds of marks we will talk about, these are the most typical four wheeled car and light duty truck marks. (Other vehicles, such as motorcycles, have different specific marks).



Light to Dark or Dark to Light




All marks can be placed into two categories when referencing the management of the vehicle which made them. Light to dark marks (in the direction the vehicle was traveling) support a vehicle making the marks through some kind of deceleration (extra points if you wanted to read “negative acceleration”). Dark to light marks (again, in the direction the vehicle was traveling) support a vehicle making the marks through some form of acceleration, usually excessive wheel spin.



Darker from the Middle, Darker on the Outsides, or Uniform


Marks that are darker in the center indicate a tire that’s overinflated, conversely marks that are darker on the outside edges indicate a tire which is underinflated. Indicate a tire.

ABS Versus Regular Marks




ABS (Anti-lock Brake System) marks are lighter than conventional marks and have more tire tread definition in them, Non-ABS marks rarely have tread definition inside them. ABS marks are also shorter when compared to non ABS marks from a vehicle traveling in precisely the speed.



What else can skid marks tell us?



As you have already found skid marks may tell us about the tires inflation, ABS or non-ABS braking, and direction of travel. Marks can also tell us something when and in which the decision to brake occurred. This is the most under-utilized and under explored aspect even more so in speed crashes. Some basic calculations can be made, using a variety of aspects of the skid marks, to determine where the driver made the decision.

Why is this so important? Consider the following illustration.







This drawing is a timeless teaching example used to demonstrate the value of skid marks. Consider this situation, the blue car says he had the green light and was hit at the intersection. The car says so that that he braked hard he also had the light and saw the car. There isn’t any other evidence or witnesses.



Now the student would be asked to calculate the position of the cars once the decision to brake was created using the beginning of the skid marks, ultimately this would place the vehicles in the place labeled 1.



Now the apparent problem with the red car’s situation now that we have used the skid marks to ascertain where he determined to brake, a construction blocks his view of the blue car (position 1 for both vehicles). This begs the question as to why did he decide then to brake? The answer, the light was red for the red car and the driver was braking for traffic lighting, not the blue car making the red car culpable in this situation as the physical evidence affirms the “at fault” party.



Another valuable piece of advice is that rubber is biodegradable and there are naturally occurring nitrogen based bacteria that “eat” rubber. These bacteria are competitive and will eat rubber in most environments, therefore if you’re trying to determine causality and the “at fault” party, it is in your best interest to take pictures of the roadway whenever possible. Skid marks are gone in a brief amount of time.



Skid marks are a valuable item of evidence and a great tool for determining many facets in a collision; it is extremely important none of them are overlooked or underestimated.

Additional Topics: Weakened Ligaments After Whiplash




Whiplash is a commonly reported injury after an individual has been involved in an automobile accident. During an auto accident, the sheer force of the impact often causes the head and neck of the victim to jerk abruptly, back-and-forth, causing damage to the complex structures surrounding the cervical spine. Chiropractic care is a safe and effective, alternative treatment option utilized to help decrease the symptoms of whiplash.

Pain in the Quadratus Lumborum Muscle

A majority of the population have at some point experienced low back pain in their lifetimes. Although low back pain is recognized to result from numerous conditions or injuries on the lumbar spine, muscle strains such as a quadratus lumborum muscle strain, are believed to be a leading cause for the recognizable symptoms of pain and discomfort.
The quadratus lumborum muscle is a sizable muscle in the shape of a triangle, located deep on each respective side of the lower back. The role of the wide muscular tissue is to grant mobility to the lumbar spine in sequence for the torso to move laterally from side to side as well as extend and stabilize the lower spine to improve posture. When this muscle is strained or pulled, the symptoms can restrict movement on the lower back and since the muscular tissue is so extensive, recovery from this type of injury usually requires more time and patience to fully heal.

Achilles Tendon Injury

Achilles tendonitis is a medical term used to describe a condition resulting in irritation of the large tendon, the Achilles tendon. Found in the back of the ankle, this condition is recognized as a common cause for injury among athletes. Excessive use of the Achilles tendon results in inflammation together with swelling and pain.
The development of Achilles tendonitis can be associated with two important factors, most frequently among athletes, which are, lack of flexibility and over-pronation. With age, the tendons will begin to lose flexibility, just the same as other tissues in the body. This change causes the tendons to become more rigid and more vulnerable to injury. For some people, the ankle may roll too far downward and inward with each step they take. This is called over-pronation, which places more stress on the tendons and ligaments of the foot, contributing to injury if not corrected.
Achilles tendonitis may also develop from other factors. An increase in an athlete’s …

5 Common Causes for Shoulder Pain

The shoulders are the most mobile joints in the human body. Because the ball of the humerus is designed to be larger than the shoulder socket that holds it, the shoulders need to be supported by muscles, tendons, and ligaments to secure them in a stable or natural position. Since the shoulder can be unstable, it is often a site for many common complications. Below are 5 common causes of shoulder pain and their associated symptoms.
Rotator Cuff Tear
Rotator cuff tears within the shoulder are a very common type of shoulder injury. The rotator cuff consists of a set of four muscles: the supraspinatus, the infraspinatus, the subscapularis, and the teres minor. All of these muscles are attached to the bones of the shoulders by tendons, which purspose is to support, stabilize, and grant the arm movement to move up, down and rotate. The rotator cuff ensures that the arm remains in the shoulder socket. Damage or injury from an accident or gradual wear and tear can result in inflammation to t…
