New NHTSA Study

drowsy drivingWhen dealing with a ‘ton of data’ about crashes, causes, contributing factors, costs and such, it can take several years to fully value and understand what it all means.  Why?

  1. First, there’s a lot to analyze.  
  2. Second, not all final crash costs are known until the bulk of medical treatments have been completed and reported.  
  3. Third, data about the source data becomes available during the analysis process (we gain insights as the analysis proceeds — sometimes causing us to reverse and re-examine details).

With these points in mind, the National Highway Traffic Safety Administration (NHTSA) recently released a new study of “The Economic and Societal Impact Of Motor Vehicle Crashes” that occurred during 2010.

We wanted to share some select quotes from the study to highlight several key findings.

In 2010, there were 32,999 people killed, 3.9 million were injured, and 24 million vehicles were damaged in motor vehicle crashes in the United States. The economic costs of these crashes totaled $277 billion. Included in these losses are lost productivity, medical costs, legal and court costs, emergency service costs (EMS), insurance administration costs, congestion costs, property damage, and workplace losses. The $277 billion cost of motor vehicle crashes represents the equivalent of nearly $897 for each of the 308.7 million people living in the United States, and 1.9 percent of the $14.96 trillion real U.S. Gross Domestic Product for 2010. These figures include both police-reported and unreported crashes. When quality of life valuations are considered, the total value of societal harm from motor vehicle crashes in 2010 was $871 billion. Lost market and household productivity accounted for $93 billion of the total $277 billion economic costs, while property damage accounted for $76 billion. Medical expenses totaled $35 billion. Congestion caused by crashes, including travel delay, excess fuel consumption, greenhouse gases and criteria pollutants accounted for $28 billion. Each fatality resulted in an average discounted lifetime cost of $1.4 million. Public revenues paid for roughly 9 percent of all motor vehicle crash costs, costing tax payers $24 billion in 2010, the equivalent of over $200 in added taxes for every household in the United States.

Clearly, traffic crashes cost a lot of money!

Key contributing factors to the crash data in 2010 included:

  • Impaired (drunk) driving
  • Speed
  • Distraction
  • Seat belts saved many, but some (3,350 people) perished for failing to use their restraints properly/consistently

It is staggering to realize that during 2010, there were more than 3.9 million people injured in 13.6 million motor vehicle crashes (including about 33,000 fatalities).  Alcohol-involved crashes accounted for about 21 percent of all crash costs and a third of all road deaths.

Speed-related crashes (where at least one driver was exceeding the posted limit OR driving too fast for conditions) were connected to 10,536 fatalities (another third of the total for the year).

So, in hindsight, if all drivers had:

  1. worn their seatbelts properly,
  2. avoided driving while impaired and
  3. followed the speed limit (or driven with regard to local conditions)

then, about two-thirds of all road deaths could have been avoided (22,000 lives saved).

The opening paragraph of the study that deals with speeding says a lot in a few words:

Excess speed can contribute to both the frequency and severity of motor vehicle crashes. At higher speeds, additional time is required to stop a vehicle and more distance is traveled before corrective maneuvers can be implemented. Speeding reduces a driver’s ability to react to emergencies created by driver inattention; by unsafe maneuvers of other vehicles; by roadway hazards; by vehicle system failures (such as tire blowouts); or by hazardous weather conditions. The fact that a vehicle was exceeding the speed limit does not necessarily mean that this was the cause of the crash, but the probability of avoiding the crash would likely be greater had the driver or drivers been traveling at slower speeds. A speed-related crash is defined as any crash in which the police indicate that one or more drivers involved was exceeding the posted speed limit, driving too fast for conditions, driving at a speed greater than reasonable or prudent, exceeding a special speed limit or zone, or racing.

In short, speeding robs you of needed reaction time – you need to make judgments faster and have less room to maneuver in an emergency.  Each of us can choose to drive slower and buy time to react and respond, but we’re often in a ‘hurry’ to get to our destination, and choose to increase or risk.

Police

The study reminded us of the urgent need for ALL drivers of cars, trucks, buses to properly use restraints such as seatbelts whenever driving.  Consider these statistics:

When properly fastened, seat belts provide significant protection to vehicle occupants involved in a crash. The simple act of buckling a seat belt can improve an occupant’s chance of surviving a potentially fatal crash by from 44 to 73 percent, depending on the type of vehicle and seating position involved. They are also highly effective against serious nonfatal injuries. Belts reduce the chance of receiving an MAIS 2-5 injury (moderate to critical) by 49 to 78 percent.

MirrorPoster_72dpiThe report did not have kind words for the use of motorcycles (however, I could speculate that the authors were concerned for the welfare of riders in delivering their findings in a stark way):

Motorcycles are the most hazardous form of motor vehicle transportation. The lack of external protection provided by vehicle structure, the lack of internal protection provided by seat belts and air bags, their speed capability, the propensity for riders to become airborne through ejection, and the relative instability inherent with riding a two-wheeled vehicle all contribute to making the motorcycle the most risky passenger vehicle. In 2010, 4,518 motorcyclists were killed and 96,000 were injured in police-reported crashes on our Nation’s roadways. This represents 14 percent of all traffic fatalities and 3 percent of all police-reported injuries. Motorcycles accounted for only 0.6 percent of all vehicle miles traveled in 2010. Per vehicle mile traveled in 2010, a motorcyclist was about 30 times more likely than a passenger car occupant to die in a motor vehicle traffic crash and 5 times more likely to be injured. The difference in these proportions reflects the more severe injury profile that results from motorcycle crashes. Over the past several decades motorcycle fatalities and injuries have generally increased relative to those in other vehicle types.

Other observations included a good reminder that intersections continue to be a prime location for crashes since there are so many ways that vehicles, pedestrians and cyclists can interact with each other during turns or even while transiting the intersection (straight across).

SUMMARY

While the data summarizes activity from 2010, we can learn a lot about behavior, choices and safety results.  There’s never an inappropriate time to share safety messages with drivers about obeying traffic laws, using seatbelts and avoiding risk taking (i.e. driving while impaired, distracted driving, etc.)
