The Role of Driver-Assistance Technology in Accident Reconstruction

Self-driving cars aren’t here yet, but Advanced Driver Assist Systems (ADAS) are widespread. These systems can independently warn drivers of potential risks, steer, brake and accelerate. As accident reconstruction experts, we can already see the influence of ADAS in the crash data we download from cars. They are changing the way we reconstruct accidents, and […]

Autonomous vehicle braking: still a bit hit and miss

Many new cars automatically brake before striking another vehicle in their path. Though automakers have coined different names for this new feature, all of these auto emergency braking systems operate in much the same way: they use a combination of cameras, radar and lidar to “look” ahead for obstacles and then apply the brakes to […]

Safely Towing a Trailer

Trailers are an important part of many family vacations, but they can also spell tragedy if they are not properly equipped, properly set up and properly towed. Tow vehicles handle, brake and corner differently when towing a trailer. Stopping distances can be twice as long when towing a trailer, and during cornering the trailer’s wheels […]

Guardrail End Treatments

Roadside guardrails make our roads safer, but the ends of these guardrails need protection, or end treatments, to prevent them from becoming roadside hazards of their own. Recent court cases involving some end treatments have focused media and public attention on the potential hazards associated with these special features of guardrails. The ends of guardrails […]

Three Factors for Assessing a Driver’s Emergency Response

A driver who fails to avoid a roadway hazard, such as a pedestrian, cyclist or other car, could have his pre-crash responses closely scrutinized if the crash is investigated.  Driver responses are generally scrutinized in three ways: 1) response speed, 2) response choice, and 3) response magnitude. Response Speed The time it takes a driver […]

There’s Something in the Road – Now What?!

Drivers predictably encounter the unpredictable. Whether as benign as a newspaper blowing across the road or as serious as a child darting from the curb, drivers must decide what to do when confronted with these situations. In the case of the blowing newspaper, a driver may decide to do nothing, whereas in more serious situations, […]

Recreational Vehicle Accident Reconstruction

The techniques for reconstructing motor vehicle collisions are similar whether they involve passenger cars, pickups, SUVs, and even large trucks. There are, however, unique challenges involved in the reconstruction of All Terrain Vehicle (ATV) and snowmobile collisions. The first challenge is a lack of data. Unlike other types of vehicles, far less standardized testing and […]

Benefits and Complications of Electronic Stability Control (ESC)

Until recently, automotive safety efforts have focused on reducing the likelihood of occupant injuries or fatalities during a collision. In the past decade, however, the automotive world has shifted its focus to active safety: systems designed to prevent collisions in the first place. Electronic Stability Control (ESC) is the first active safety system that assists […]

Electronic Crash Data in Heavy Trucks and Buses

Accidents involving heavy vehicles can result in large injury and damage claims. The key to resolving these claims efficiently and fairly may be contained in one of the many on-board computer modules found in modern vehicles. The electronic engine control module, or ECM, is the most common source of electronic crash data in heavy trucks […]

The Potentially Counterintuitive Effects of Witness Evidence

Witness evidence following a car accident can be a tricky thing. Some witnesses recall considerable detail, whereas others recall very little. A witness may accurately recall portions of an event, but then confuse the sequence of events or inaccurately estimate distances and times. Some witnesses may even alter or exaggerate their evidence to try to […]
