Determine Speed of Crash

Can the Speed of a Vehicle Be Determined After a Crash?

Speed Determined After Crash - Verifying Fault and Injuries After a Crash.


Vehicle speed is crucial in verifying fault and injuries after a crash. After a collision, if you can show that different drivers hit you at high speed, you can use that as proof of the driver’s carelessness or even reckless driving. Further, you can calculate the rate of a car hit to prove that that accident caused your damages. Car damage at different speeds can be shown a number of ways.


For example, you can show that another vehicle was going fast when it got into a rear-end accident in your car.  Then you will have proof that shows that your whiplash trauma, post-traumatic stress, and dented bumper was a result of the collision and not some previous incident.

Accident Reconstruction Specialists Can Prove Vehicle Speed


When a significant injury award is at stake, both parties to a lawsuit might hire expert experts to present the jury with evidence about the collision. These specialists gather evidence from the collision scene. They then use scientific methods to make opinions about circumstances such as a car’s rate of travel, when a driver applied the breaks, or whether he or she veered to evade the impact.


To determine a vehicle’s speed, a specialist can estimate the length of skid marks and the resulting damage that the car sustained upon contact. Automakers and regulatory bureaus keep information about the speeds at which bumpers, crumple zones, and side panels will fail.

Using Evidence From the Collision Scene to Ascertain Speed

Let’s assume, for example, that a vehicle has a bumper that can endure impacts of up to 10 mph. After an accident, a destroyed bumper will show a higher speed. Yet the crumple zone, which will fail at collisions higher than 30 mph, is intact. From this information, a specialist can reason that the collision speed was somewhere between 10 and 30mph.


Assume that 150 ft skid marks are leading up to the point of collision. A specialist would examine the street surface conditions at the time of the crash, research the car’s braking performance, and determine the kind of tires were on the vehicle on the day of the accident.


Based on this knowledge, a specialist can calculate the estimated speed at which the vehicle must have been moving to be still going between 10 and 30 mph after breaking for 150 feet. Some sports vehicles can decelerate from 60 mph in 100 feet. Trucks, on the other hand, would take double or triple this distance to decelerate.


Witnesses and Accident Footage Can Help Establish Speed


Collision reconstruction experts are costly, so they only work on large stakes matters. For the ordinary fender bender, attorneys and insurance adjusters usually rely on eyewitness statements and accident footage to ascertain speed.


Although eyewitnesses are notably unpredictable, attorneys will ask people at the scene how many seconds it took for a vehicle to traverse an intersection and use that number to determine that car’s rate. A more safe method is to gather footage from traffic cameras or the security cameras of a local store that may have captured the accident.


Finally, many contemporary vehicles have so-called “black boxes” that document vehicle data such as location and speed. An attorney or detective can download data from the vehicle’s black box and apply it as proof of a vehicle’s speed at the time of the accident. Until all cars become equipped with this state-of-the-art technology, however, attorneys will rely on older, less reliable methods for determining vehicle speed.
