Teen Driving App Effective In Modifying Teen Driving Behavior
February 9, 2015
A teen driving app for smartphones, developed by the University of Minnesota’s HumanFIRST Laboratory, is showing a lot of promise as an effective tool to modify teen driving behavior and keep teen drivers safe on the road.
There have been a lot of apps and different products developed over the years with the same intent but the developers of this app claim that this is the first developed based on years of scientific research.
Funded with $2.5 million by the Minnesota Department of Transportation, the HumanFIRST Laboratory spent almost ten years examining the issues surrounding teen crashes and developing the app. Those studies were followed up by a year-long, in-vehicle study involving teens and their parents.
The teen driving app is known as the Teen Driver Support System (TDSS) and among other things, the app:
- Prohibits the use of cell phones while the vehicle is in motion except to make 911 calls.
- Warns the teen driver if he or she is speeding or running a stop sign or red light.
- Warns that the teen is driving aggressively.
- Warns the teen that parents will be notified if the dangerous driving behavior continues.
- Notifies parents via text message if the warnings fail to stop the dangerous driving behavior.
- Provides parents with a website that documents the teen’s driving behavior over a longer period of time.
In the in-vehicle study, cars belonging to teen drivers were outfitted with instrumentation to record their driving behavior and the teen drivers were divided into three groups:
- Drivers with no app (control group).
- Drivers with app that provided warnings but didn’t notify parents.
- Drivers with app that provided warnings and notified parents.
The teen drivers without the app showed a greater tendency to engage in distracting and risky behaviors such as, speeding more than seven mph over the posted speed limit and using the cell phone both for calls and texting while driving. The app that only provided warnings was highly effective in modifying teen driving behavior but, as might be expected, the app that provided both warnings and parental notification had the most dramatic effect on the teen’s driving behavior.
Both the teens and parents involved in the study gave the driving app high marks although, also to be expected, the teens weren’t as enthusiastic about the app as their parents:
- 60 to 75 percent of teens had a favorable opinion of the system.
- More than 90 percent of parents had a favorable opinion of the system and;
- 90 percent of parents would recommend the app to other parents of teen drivers.
While the TDSS teen driving app isn’t yet available for general use, the University of Minnesota’s Office for Technology Commercialization is studying the system and the team hopes it will be available for general use within a year.

Best States For Teen Drivers: Florida Ranks 34th
January 14, 2015
In a list of best states for teen drivers, Florida ranked 34th according to a survey conducted for Wallet Hub. Wallet Hub is a website designed as a one-stop site to help individuals and businesses make financial decisions and their teen driver survey is primarily focused on the financial aspect of teen drivers in the home. However, teen driver safety issues and laws designed to keep teen drivers safe play a big part in the total cost of teen driving.
To conduct their survey, the researchers considered various aspects that contribute to cost and safety where teen drivers are concerned. Factors that were considered included:
- The number of teen drivers in each state
- Teen driver fatalities
- Impaired-driving laws
- Graduated driving laws
- Average cost of car repairs
- Cost of insurance
A correlation can be seen between strong graduated driving license laws (GDL) and teen driver safety. Several studies have shown that states with strong GDL laws have lower teen fatality rates. The Insurance Institute for Highway Safety (IIHS) created a GDL crash reduction calculator that shows Florida would experience a 20 percent reduction in insurance rates and a 45 percent reduction in teen fatalities if the state were to adopt the strongest GDL laws on the books in other states.

Teens Killed More Often In Older Cars
January 7, 2015
The older cars passed down to teen drivers may not be the best choice when it comes to keeping teens safe on the road. Research by the Insurance Institute for Highway Safety (IIHS), shows that most teens killed in traffic crashes were driving a vehicle that was at least six years old and almost half were driving vehicles that were eleven years old or older.

Parents Are Aware Of Alcohol Use At Teen Parties
December 17, 2014
A new study shows that most parents are aware of alcohol use at teen parties hosted in their homes. This disturbing fact came to light in a study printed in The Journal of Primary Prevention. The researchers gathered their data through phone interviews of 1,121 teens in 50 mid-size California cities over a two year period.
The good news from the study is that most of the teens interviewed hadn’t hosted a party where alcohol was used. However, among those that had hosted a party during the previous twelve months, thirty nine percent reported that there was alcohol at their last party. The alcohol was supplied by multiple sources.

Ask The Driving School Instructor: Braking Distance VS Stopping Distance
December 3, 2014
Question: I’m studying for my driving exam and I’m confused about the difference between stopping distance and braking distance.
Answer: It can be a little confusing, I’ll try to sort it out for you.
If you encounter an emergency on the road requiring you to stop suddenly, there are two parts that make up the total stopping distance.
- Reaction distance
- Braking distance
When you’re in an emergency situation, it takes time to react to the emergency, to brake, and to finally bring your vehicle to a complete stop. Remember that your vehicle is traveling a surprisingly long distance every second. At 40 mph, your vehicle will travel approximately 60 feet per second and a lot can happen in that short amount of time.
Reaction time
The time it takes you to react and respond to an emergency can be broken down into three parts:
- Perception or awareness time
- Decision time
- Action time
Let’s look at each part by imagining a scenario that requires you to make a sudden stop. Let’s say that you are traveling at 40 mph when the driver of the car ahead of you suddenly applies his brakes.
Perception time
The perception or awareness time is how long it takes before you are even aware that the driver ahead is suddenly stopping. If you aren’t expecting an emergency, it will take time before you realize that the car ahead is suddenly braking
Decision time
Now that you’re aware of the emergency ahead, you have to decide what to do. Will you hit the brakes or swerve into another lane to go around? If you try to change lanes, is the lane clear or are there other vehicles that may be in the way? It takes time to decide what to do. In our emergency, let’s say that you decide to hit the brakes but that decision took time
Action time
Now that you’ve decided you’re going to brake, you have to move your foot from the gas pedal to the brake pedal and push it all the way down. That also ate up precious time.
For the average person, the total reaction time can take from three-quarters to a full second. At 40 mph, if your reaction time is one full second, you’ll have traveled almost 60 feet before applying the brakes.
Braking Distance
Now that you’ve applied the brakes, it still takes time to come to a complete stop. For an average car that weighs almost 3,000 pounds, that can take up to 60 feet.
Total stopping distance
So, the total stopping distance is made up of both the reaction distance plus the braking distance. Adding the two together means that, at 40 mph, it can take up to 120 feet before your vehicle will come to a complete stop. That’s why maintaining a safe following distance between you and the vehicle ahead is so important.
