The Truck Crash Site – Collecting Evidence at the Crash Site
Truck crash site conditions Helps explain collisions
The process of collecting and analyzing evidence of motor vehicle collisions – particularly the types of serious injuries and fatal collisions that are more likely to result from large heavy vehicles like trucks – is a combination of collecting data from and on those involved in the accident, by collecting data on the vehicles and the physical site of the truck accident, then analyzing and reconstructing the incident based on this evidence.
Often, crucial evidence can only be gathered through a truck accident site investigation, including evidence from vehicles that may indicate mechanical or other faults and evidence such as skid marks, gouges on the road surface, burns and other marks, and nearby damage. structures such as guardrails and signage that may help explain how the incident occurred. Investigating, securing, and analyzing this physical evidence is usually a significant early effort on the part of any qualified personal injury attorney seeking to understand how the accident occurred and obtain appropriate compensation for the injuries. customers who were injured in the incident.
Damage at the site of the truck accident to the roadway and nearby objects
Many types of damage can be caused to the physical environment during a truck accident, or even just by moving a truck through the location. Evidence of this damage is sometimes not visible until immediately afterwards, while other evidence may linger for weeks or even months. Observing this evidence and understanding what caused it is often important for an investigator or personal injury attorney to determine how the accident occurred.
For instance, full-size trucks are obviously much bigger than passenger cars and, therefore, they can cause damage to objects near the roadway that a standard-size automobile would not. Tree branches overhanging a road can be hit by a tractor or trailer while they are still several feet higher than other vehicles. Smaller, less well-designed and constructed roads can suffer surface damage from heavily laden trucks that would not be caused by cars weighing only one-twentieth their weight.
Observing and recording this damage can sometimes indicate that other parties have some degree of legal liability for an accident and resulting injuries – overhanging tree limbs can place some liability on landowners or local municipalities that have not properly removed or pruned the branches.
At other times, damage to the road environment may point directly to truck driver failures – for example, failing to observe and obey signs warning of low overhead power lines or signs warning that a particular road must not be used by heavy vehicles.
Tire marks at the scene of the truck accident
There are many types of tire brands and they can be essential pieces of evidence to explain how and why truck accidents and other motor vehicle collisions happen. Among these types, each with their own story to tell, are:
- Skid marks – These are the marks often left by a tire whose wheel brakes are locked or nearly locked, such that the tire has stopped spinning as fast as the road surface passes beneath it. This is certainly evidence that the driver of the vehicle was trying to brake, but the absence of skid marks does not necessarily indicate that the driver was not trying to brake — a lot of things like water or ice on the road surface may prevent skid marks, or the driver may not have braked hard enough to lock the brakes.
- Skip skid marks – These are similar to regular skid marks, but look more like dotted lines, usually caused when the axle carrying the skid tire bounces up and down when braking.
- Flat Tire Marks – Wider tire marks can indicate a tire that lost pressure due to a fault or was underinflated. They can also be a sign of too heavy a load in the vehicle.
- Tire Marks – Left in softer materials such as gravel or dirt in the medians or shoulders of the roadway, these marks indicate where the truck left or entered the roadway before, during and after a collision.
- Tire Yaw Marks – These marks or skid marks indicate a vehicle that was experiencing significant lateral (sideways) movement, such as when trying to swerve or turn at high speed.
- Crash tire marks – Short tire or skid marks made at the time of collision when a vehicle is suddenly forced to stop or move in a different direction, these marks are often useful for locating crash points impact in crashes where the vehicles continued to move after the collision.
Other physical evidence at the scene of the truck accident
A large part of the physical evidence of road accidents won’t linger long after the collision itself – glass shards and fuel spills are usually cleaned up quickly for safety reasons, for example. Other types of physical evidence will last longer, such as tire tracks and skid marks which may linger until traffic or weather erases them. Personal injury attorneys who investigate truck accident scenes on behalf of their clients understand the importance of bringing an investigator to the scene as soon as possible to collect and preserve remaining evidence.
Certain types of physical evidence on the site may remain present for much longer. Sometimes vehicular debris can be ejected by vehicles onto road shoulders or nearby vegetation and not be observed immediately after the accident or simply not cleaned up right away. At other times, debris may simply be swept off the roadway as a quick safety measure. In these cases, the evidence may be of limited value since it may be uncertain when it was moved or changed after the accident.
Some types of accident scene evidence can persist and be useful for much longer. One category is gouge marks in the pavement surface. These can remain visible for years, until the next road resurfacing. They are often caused at or near a point of impact when parts of a vehicle protruding from its underside (or which are forcibly torn from the vehicle) come into contact with the road surface and leave a footprint. One type of gouge mark that is relatively well known is the marks left by the heads of bolts thrown downward from a car engine oil pan – this is usually the lowest point of a gouge. a car engine, and when an impact occurs at the front of a car it tends to force the engine compartment down with the oil pan bolts leaving a clear gouge mark indicating the point of damage ‘impact.
