The recent limousine crash in Schoharie, New York raises some safety concerns for large modified vehicles. The accident, which took the lives of 20 individuals, involved a large modified version of a Ford Excursion that had been essentially cut in half with the middle extended, then re-assembled to form a larger vehicle. The National Highway Traffic Safety Administration, otherwise known as NHTSA, stated that this was the most deadly transportation disaster in almost 10 years. The issues that surround the case include whether or not the limousine driver was properly licensed, and the shoddy inspection history held by the subject limousine company and failed inspection results. The history of the vehicle involved in the accident is not completely known to the public, but it is evident from the details that have been released that the vehicle began its life as a 2001 Excursion. While many limousines start out as a normal passenger vehicle, it is common for the limousines to be completely custom made by a third party, lengthening the vehicle to accommodate more people inside. In fact, the term “stretch” limousine appropriately defines what these vehicles are: stretched versions of a vehicle that have extra-long wheelbases, multiple windows in a row between front and rear, and have the capability of holding 10 or more passengers. Sometimes these custom modified vehicles are termed “Frankenstein” vehicles However, simply stretching a vehicle to turn it into a limousine has some very serious side effects. Most importantly, when a vehicle is modified with new custom parts and components, some of the original safety systems may be left out. Things like airbags and seatbelts, which were originally part of the vehicle, are removed from modified limousines. Unfortunately regulations on seatbelt requirements for rear seat passengers, just like those paying customers who hire a limousine service, are not regulated the same in every state. In fact, in New York, where this accident occurred, rear seated passengers are not required to wear seatbelts. Ultimately this accident indicated that there is a significant gap in regulation around the limousine industry that will likely be addressed by the National Highway Traffic Safety Administration soon.

The European Union is working to develop a new type of airspace that is focused on operation of drones. Drones, or unmanned aerial vehicles (UAV for short) are becoming more and more popular throughout the world and the European Union is proactively developing a system to accommodate these new aircrafts. Drone traffic management poses a unique number of challenges. Mostly, because of the sheer number of drones that are flown in the sky, monitoring and managing positioning of drones and keeping drones away from manned aircraft is a significant challenge. Also, because drones are very small, many drones are not effectively tracked by current technology. The European Union is developing a system to accomplish effective drone flight management by next year.
The Geneva based drone body that handles air navigation, Skyguide, recently joined forces with AirMap, a traffic management system, to collectively develop an infrastructure to manage drone flight across all of Europe in an airspace for low-level flight dubbed U-Space. U-Space will be defined as a flight altitude from ground level up to about 150 meters in height for which drone flight will be managed. New surveillance technologies developed for U-Space will be able to effectively track drone flights in U-Space.
In the past five years, Skyguide flight requests have increased over ten times, indicating that drone operation is increasing dramatically. While collectively managing drones that fly in U-space and follow protocols set forth by Skyguide pose little threat to manned aircraft, those UAV drones that are flying unauthorized in U-Space may pose significant threat by flying too high, flying without proper tracking devices, or other illegal operations. Because of this Skyguide and AirMap are working to develop a Universal Traffic Management system that will not only track drones that have proper on-board tracking devices, but also track those drones that do not have the tracking devices installed, or the tracking devices were disabled. U-space regulations are currently being developed to cover a variety of flight conditions.

A new study carried out by the Insurance Institute for Highway Safety has shed new light on the topic of seat belts and rear passengers. The study determined that the mindset of adult passengers in motor vehicles is that the rear seats are automatically safer than the front seats and that, in many cases, seatbelts are optional when riding as a passenger in the rear of a vehicle. The study showed that approximately 28 percent of individuals who participated did not wear their seat belts while in the back seats of a vehicle. 91 percent of individuals who participated claimed that they would wear seatbelts while in the front seat, however. Interestingly, of those who admitted not always using safety belts while in the back seat of a vehicle, approximately 4 out of 5 individuals stated that they would not use seat belts at all while on short trips, such as during ride-shares, taxis, or Uber.
The mindset that the rear seat is automatically safer than the front seat may have come from the early advent of seat belts in vehicles during the 1960’s and 1970’s. During this time, the rear seat was considered safer than the front seats because none of the seats were required to have seat belts. Without any seat belts, the rear seat is technically safer because the occupant is less likely to impact the hard dashboard in the event of an impact. However, with safety belts now required by federal law, the rear seat is basically just as dangerous as the front seat during a car accident.
The Insurance Institute for Highway Safety study identified that the age group of adults who were the least likely to wear seat belts while in the rear of a vehicle was those individuals 35 to 54 years of age. Only 60 percent of these individuals reported to wear seatbelts in the rear of a vehicle, compared to 76 percent 55 years old or older, and 73 percent of those aged 18 to 34 years.
The topic of drowsy driving has been visited by researchers many times before now, however new data has shown that the issue of drowsy driving is more serious than previously thought. Every driver has probably been through an episode of tiredness when behind the wheel. As many have been able to arrive at their final destination while driving drowsy, many others have not arrived safely or have even been killed due to drowsy driving. The likelihood of causing an accident is definitely more severe when a driver is tired, drowsy, or otherwise sleepy. Researchers have compared the effects of driving drowsy to that of driving distracted, or even driving under the influence of alcohol. Reaction times are reduced when a driver is tired, and even worse than that, driving with your eyes closed and unconscious literally turns a moving vehicle into a lethal weapon for the driver, passengers, or others on the roadway.
The National Highway Traffic Safety Administration has worked diligently to determine accident statistics relating to driving drowsy. While it can be difficult to determine if an accident was caused by drowsy driving, estimates have been made in attempt to raise public awareness of such a dangerous behavior when behind the wheel. The National Highway Traffic Safety Administration estimates that there were approximately 846 traffic-related deaths due to drowsy driving in 2014, and over the past decade, approximately 83,000 crashes per year can be blamed on drowsy driving.
The National Highway Traffic Safety Administration has some pointers for drivers to follow to avoid driving drowsy and potentially causing an accident:

Driving on the roads and highways in the United States can be dangerous. Statistics showing the number of fatalities caused during driving have been released by the National Highway Traffic Safety Administration. NHTSA released the stats which showed that traffic deaths increased in 2016 over the number of deaths recorded during the same amount of time in 2015. The trend for traffic-related fatalities has been increasing every year since 2014. This has some researchers at NHTSA concerned and looking for an answer as to why the numbers are increasing. Experts have mentioned that the increase in deaths is due to an increase in the number of miles that Americans are driving. The amount of driving has steadily increased as the economy has improved and Americans are also taking advantage of the low cost of fuel. However, the increase in deaths has far outpaced the increase in miles driven. In fact, the increase in traffic-related deaths has risen approximately 8 percent since the beginning of 2015, where the increase in miles traveled has only increased about 3 percent.
The increase in fatalities seems to be located around certain areas of the country. For example, in the heart of New England, traffic related deaths have increased significantly; around 20 percent more than in 2015. In the western center of the United States, an area that includes North Dakota, South Dakota, Wyoming, Colorado, Utah and Nevada, the increase in fatalities has only risen about one percent.
Even more concerning is the fact that traffic-related deaths have increased even while almost all automakers have developed significant safety systems in new vehicles in an attempt to make the vehicles safer. Systems such as stability control, traction control, lane departure warnings, backup cameras and other similar systems are now common in new vehicles. Despite the increase in vehicle safety systems, traffic deaths are on the rise.

Fiat Chrysler is undergoing a new series of investigations into their dial-actuated shifters used in many of their automatic transmission-equipped vehicles. This time, Dodge models, including the model years 2014 to 2016 Durango, and the 2013 to 2017 Ram Truck are under investigation by the National Highway Traffic Safety Administration (NHTSA) because the vehicles roll away after they have been shifted into park. The dial-actuated shifters use an electronic rotary controller to actuate the mechanical shifting mechanisms inside the transmission and the actuators do not effectively shift into park in some cases, allowing the vehicle to roll away from the intended position if the vehicle is left on a slight grade without any additional resistance to movement.
NHTSA is gathering information to formulate an official recall for the Durango and Ram Truck vehicles. At this point, NHTSA is investigating how frequently and how severe the reported roll-away cases are to determine a plan of action for the recall. Up to this point, there have been 43 reported cases of Durangos or Rams moving away from the driver after the shifter was put in park, and of these 43 cases, 25 have resulted in crashes or property damage, and approximately nine incidents have resulted in personal injuries, but no fatalities have been reported due to this issue.
The dial-actuated shifter mechanism is different than the mechanism used by Chrysler in their Charger, Chrysler 300, and Grand Cherokee models that has already been recalled on over 1.1 million vehicles, however the actuation process is very similar to the previously-recalled unit. NHTSA expects that the recall of the Durango and Ram models will affect over 1 million vehicles.

- Ensure that one is getting about 7 to 8 hours of sleep per night to avoid becoming drowsy, especially if driving after dark or early in the morning.
- Avoid drinking any alcohol before driving. Driving under the influence while tired increases the risk of an accident dramatically.
- If any medication is taken that can cause drowsiness, avoid driving altogether. It is especially important to be aware of the effects that new medications can have on alertness and consciousness.
- Remain vigilant for signs of tiredness and sleepiness, such as heavy eyelids, passing over the centerline, and shortness of breath. Any signs of sleepiness should signal the driver to stop driving immediately.
