All kinds of things. Here are some of them:
-The make and model of the truck – which can tell you how wide it is. Useful knowledge if you’re trying to reconstruct an accident that happened on a very narrow road.
-If the truck had an event on data recorder, or “black box”, you can learn information about the truck’s speed, steering and braking history immediately before the accident.
-The driver’s discipline and violations history – helpful if you’re trying to establish that the company was negligent in hiring, retaining or failing to discipline him.
-The training materials for the company’s drivers – which by themselves can establish a standard of care.
-The manifest for the truck for the particular trip.
-Whether the driver was given any particular route instructions – which could, in turn, reflect on the questions of whether he was following the instructions, how the instructions were formulated, and whether the driver was in the scope of employment.
-The damage incurred to the truck because of the accident.
-The mileage and maintenance history of the truck – very useful if equipment failure was a cause of the collision.
-How much time the driver had spent behind the wheel in the 72 hours before the accident – which can tell you how much time he had not slept during that period.
I have been a lawyer over 30 years. The stakes are usually higher in a truck accident case, and a good lawyer has to know what to do if the trucking company decides to fight liability vigorously. If you’ve been hurt by a truck, talk with an experienced Cincinnati Truck Accident Attorney about the case. Call me, William Strubbe, at 513-621-4775.
Because all situations are different, and because there may be other facts pertaining to your case that I don’t know about, you should not rely on this answer for legal advice. I am not your attorney, and no lawyer client relationship has been formed.
