Reporting Road Conditions

If you’re in an accident, be sure to note the condition of the road – was it icy? Was it pouring rain? Was it dry and sunny? These are important points and used in collision reconstruction cases.

Accident reconstructionists look at the many variables that may have contributed to an accident. Road conditions are just one of the areas, here are some things they look at:

Road Conditions

  1. Bumps and potholes as well as the condition of the pavement or gravel can impact the cause of an accident.
Friction Evaluation

  1. Friction is the resisting force of motion between two surfaces when they are in contact.
  2. Friction analysis can determine the speed of a car.

Weather Conditions

  1. Road conditions are critical to an accident.
    • A record of conditions helps establish whether slippery or wet roads affected the accident and they help establish the drag and speed at the time of the accident.
    • Weather conditions are usually found in the police report and can be verified from local newspapers and weather services.

Lighting Conditions

  1. Lighting is one of the most important issues involving accidents – especially at night.
  2. Many people overestimate their ability to see at night and very often the headlights are insufficient to reveal potential collisions in time for a driver to react and avoid them.
  3. Pedestrians and cyclists are often hit at night because the road is not adequately lit or the victim is wearing dark clothing.
    • In some cases, it can be determined that the driver could not have seen the pedestrian or cyclist until it was too late.
    • Pedestrians can often see the car, however the driver cannot see the pedestrians.

Traffic Signs and Signals

  1. Examination of the relevant traffic control is crucial – especially if a driver ignored or did not see a sign or signal.
  2. Experts can:
    • Establish the timing in seconds of the delay between a set of lights turning red and the other turning green.
    • Determine if the traffic signal or sign was obstructed.
    • Analyze the placement of the signs.
