Teaching Teens to Stay Safe Behind the Wheel

Teaching Teens to Stay Safe Behind the Wheel

Why Are Teen Accidents Increasing?

Teen driving fatalities have been increasing in Tennessee and in the rest of the country, making it important for parents to teach their teens to drive safely. Teaching safe driving practices may help to save the lives of teens as well as those of others who are on the roads around them. Teen drivers have less experience than older drivers and are likelier to engage in risky behaviors. The widespread use of cell phones and apps has also contributed to the increase in accidents. There are several things that parents should keep in mind when they are teaching their teens to drive.

Teen driving fatalities steadily declined from the middle part of the 1970s until about four years ago. Since that time, the number of teen driving fatalities has been increasing. Almost 3,000 teens are killed in motor vehicle accidents every year. One of the major contributing factors to the increase in teen driving fatalities is the use of cell phones and other electronic devices while the teens are driving. Using a cell phone while driving to text, talk, check social media, or use apps diverts the attention of teens away from the road. While their eyes are off of the road, the vehicles that they are driving can travel hundreds of feet. Since they are inexperienced drivers, they may not react the correct way to avoid collisions. Other issues that have contributed to the increase in accidents include driving while drunk, speeding, not wearing seatbelts, driving while they are drowsy, and driving with passengers in their vehicles.

 

Teaching Teens to Drive Safely

Parents can help to prevent their teens from being involved in an accident by teaching them to drive safely at all times. It is a good idea for them to enroll their children in drivers’ education courses. Once they have completed these classes, the parents should regularly take them to practice driving. Parents should view the state’s required supervised driving hours as a minimum amount and should aim to teach them more. They should also model safe driving practices themselves by always wearing seat belts, following speed limits, and not checking their cell phones while they drive. Teaching teens to drive safely may save their lives and those of others.

Robotic Big Rigs Could Put More Pressure on Human Truckers

Robotic Big Rigs Could Put More Pressure on Human Truckers

The move to autonomous trucks may place added stress on Tennessee truck drivers and lead to new dangers from fatigue, disengagement and the potential for cyber terrorism. While manufacturers tout the safety of autonomous vehicles, their advent has led to questions about liability and concerns about the reaction times of drivers when they are forced to take control of the trucks in emergency situations. The Federal Motor Carrier Safety Administration recently conducted a listening session to talk about some of the potential issues that could happen when large trucks are traveling on the roadways. The agency is trying to determine what type of regulations might be in order for autonomous trucks.

Potential Dangers of Autonomous Trucks

According to Mark Rosekind, the former administrator of the National Highway Traffic Safety Administration, truck drivers who are assigned to these trucks may quickly become complacent and experience passive fatigue while they are monitoring autonomous systems and are not in control of the trucks. Among the major accidents investigated by the National Transportation Safety Board in the last few years, 20 percent were caused by fatigue.

A researcher from the Institute for Simulation and Training at the University of Central Florida conducted a study of drivers in vehicles with level 3 automation, which is when vehicles are in full automation mode but drivers are expected to remain in the vehicles and take over in the case of an emergency. The researcher found that the drivers became disengaged and exhibited passive fatigue starting about 10 minutes after they began operating the vehicles in autonomous mode. When the researcher presented a simulated emergency situation of another vehicle pulling out into traffic ahead of the vehicles, he found that the drivers’ reaction times were much slower. Passive fatigue caused slower reaction times than active fatigue.

Other concerns include the potential for attacks on interconnected systems by cyber terrorists. If cyber terrorists are able to hack into the systems that control autonomous trucks, they could wreak havoc and cause the loss of many lives in large truck accidents. There are also concerns about liability in accidents that might be caused by autonomous trucks. The FMCSA is considering ways to regulate autonomous trucks to make them safer for everyone.

Loose Lug Nut Season: When Tires Take Flight

Loose Lug Nut Season: When Tires Take Flight

In Tennessee, some accidents are caused by tires separating from vehicles on the highways that then crash into other cars. While these types of accidents are rare, some motorists are seriously injured or killed when their vehicles are struck by flying tires. Tires may separate from vehicles because their lug nuts have not been tightened enough by tire mechanics when they change the tires on the vehicle. They may also separate when the mechanics apply too much torque when they are replacing the tires, weakening the lug nuts and causing them to fail.

Dangers of Tire Separations

When tires fall off of vehicles while they are traveling on the highways, they may fly through the air and collide into other vehicles. These car accidents are sometimes deadly. In a recent case in Nevada, two cousins were killed when a tire separated from an SUV that was traveling in the opposite direction on Interstate 95. The tire crashed through the windshield of the vehicle in which they were passengers, killing them both. An engineer with MFA Forensics states that there are around 50,000 tire separations each year, and the incidents are underreported. This makes it difficult to determine the pervasiveness of the problem.

What Causes Tires to Separate?

Tires may separate from vehicles because of several maintenance issues. In 643 cases that happened between 2000 and 2003, 65 percent were caused by loose lug nuts, and 26 percent were caused by wheel bearing failures. Nearly all of the cases could have been prevented by proper maintenance. In a Canadian study, 83 percent of the reported wheel separations happened soon after the vehicles’ tires had been serviced.

Tires may separate when their lug nuts are tightened too much or not tightened enough. Mechanics that do not use the proper torque or calibrated tools when they change the tires may cause too much pressure to be applied to the lug nuts, causing them to sheer off while the vehicles are being driven. This may then lead to the tires flying off of the vehicles and striking other motorists who are traveling nearby. The mechanic shops that performed the improper maintenance may be liable to pay damages if people are killed or injured when the tires separate and fly off the vehicles.

Hand-Free Systems Are Still a Distraction for Truckers

Hand-Free Systems Are Still a Distraction for Truckers

In Tennessee, truck drivers are prohibited from using their cell phones with their hands, but hands-free systems, which are also distracting, are allowed. The Federal Motor Carrier Safety Administration prohibits the use of handheld cell phones while truck drivers are driving. The drivers are also forbidden from using hands-free phones if they must press more than one button to make a call. While the FMCSA recognizes the dangers of texting while driving and has moved to make doing so illegal, using a hands-free system is also distracting and may lead to truck accidents.

FMCSA Rules About Cell Phones

The FMCSA has rules in place about the use of cell phones while truck drivers are driving. They are prohibited from using phones that require them to hold the phones in their hands when they make calls. They are also prohibited from using phones that require them to push more than a single button to make a call. Finally, they cannot have their phones positioned in such a way that they are forced to reach for their phones, making them lean over and out of a seated position.

Why Hands-free Systems Are Distracting

Dialing on a hand-held cell phone, reading text messages or typing messages cause three different types of distraction, including visual, manual and cognitive distraction. Hands-free systems take away the problems of visual distraction and manual distraction because the drivers can keep their eyes on the roads and their hands on the wheel. However, when their cognitive attention is divided between responding to a message or talking and concentrating on the road, they are still cognitively distracted.

In addition, while hands-free system manufacturers claim that visual distraction is eliminated, most drivers who use hands-free systems still tend to glance at their phones when they are sending voice texts. Most people check to see if what they say is being translated accurately because the translators are known for making mistakes.

Because people tend to think that they are being safe when they use hands-free systems, this may give them a false sense of security when they are driving. Truck drivers may be distracted while they are sending text messages by voice or when they are talking on the phone over their hands-free systems, and these issues may result in accidents.

Voice Command Helps Older Drivers Stay Focused on the Road Ahead

Voice Command Helps Older Drivers Stay Focused on the Road Ahead

Infotainment systems that use single-voice commands help older drivers keep their attention focused on the roads much better than multi-step systems or manipulating knobs on the dashboard. Single-step voice command systems help drivers by reducing the amount of visual distraction. With multi-step voice command systems, researchers have found that as age increases, the systems become more distracting to the drivers. However, they found that single-command systems do not show a correlation between age and increased distraction.

Single-Command Voice Systems Safer

According to the Insurance Institute for Highway Safety, voice command systems are less distracting for drivers than infotainment systems that require people to glance at them or manually manipulate them. Researchers evaluated the effects that the characteristics of various interfaces had on drivers’ ability to focus and determined that those that used single-step voice commands impacted driver focus less than those that required multiple-step commands.

The researchers studied 80 drivers on Boston-area interstates between the ages of 20 and 66 while they made phone calls. Half of the drivers drove vehicles that were equipped with single-command systems while the other half drove vehicles that were equipped with multiple-step command systems. After the drivers were trained on how to use the infotainment systems, cameras were used to analyze the effects of using the systems.

The researchers found that for each 10-year increase in age, 3.7 more seconds were required for drivers to complete their calls with the multiple-step systems. Long glances away from the road lasting two seconds or more also increased by 0.4 percentage points. In the single-voice command vehicles, there was no corresponding increase in distraction with increasing age. Regardless of how old they were, the drivers that used single-voice command systems were able to keep their eyes on the road 85 percent of the time while they were making phone calls.

The findings indicate that installing single-voice command systems in vehicles that are owned by older drivers may help them to keep their attention focused on the roads. These systems may help older drivers avoid accidents that are caused by distracted driving.
