(Press-News.org) Almost half of teen drivers killed on US roads in the past few years were driving vehicles that were 11 or more years old, and often lacking key safety features, reveals research published online in Injury Prevention.
Parents, who are usually the ones stumping up for a car, could be putting their children's lives at risk by focusing on cost, warn the researchers.
The prevalence of fatal road traffic collisions among US teens has fallen sharply since 1996. Yet per mile driven, rates of police-reported and fatal crashes involving teens are around three times those for adult drivers.
The researchers analysed data from the US Fatality Analysis Reporting System for 2008-12. FARS collects information on all vehicle collisions on US public roads that result in at least one death within 30 days of the incident.
Using vehicle information databases, they compared the types, sizes, and ages of vehicles driven by 2420 teen drivers (15-17 year olds) with those driven by 18,975 middle aged drivers (35-50 year olds).
Two thirds of the teen drivers who died were in a car: 29% were driving a mini or small car; and just over one in three (35%) were driving a mid-size or larger car. The rest were driving pickups (17%) and sport utility vehicles, otherwise known as SUVs (17%).
Fatally injured teen drivers were significantly more likely than middle aged drivers to have been at the wheel of a small or mini car (29% vs 20%) or a mid-size car (23% vs 16%), and significantly less likely to have been driving a large pickup (10% vs 16%).
Most of the teen drivers (82%) who were killed, were in vehicles that were at least 6 years old. A third (34%) were 6-10 years old, and a similar proportion (31%) were 11-15 years old. Some 17% of the vehicles involved in fatal collisions were 16 or more years old.
Fatally injured teens were almost twice as likely as middle aged drivers to be driving a car that was 11-15 years old (20% vs 12%).
Only around one in 10 of the fatally injured teens' vehicles had Electronic Stability Control (ESC) available as standard (3%) or as an optional feature (8%).
ESC is particularly useful in cases where the driver loses control--something that is relatively common among young drivers who have just passed their driving test, say the researchers. It can cut the risk of death in single vehicle crashes by around half and by 20% in crashes involving several vehicles.
In all, only around a third (36%) of teen and middle-aged drivers' vehicles had optional or standard air bags, but the vehicles driven by adults were slightly more likely to have them as standard equipment.
Given that teen drivers are more likely to be involved in road traffic collisions than older drivers, it is especially important that they drive vehicles fitted with key safety features, which afford good protection in the event of a crash, say the authors.
"Larger, heavier vehicles generally provide much better crash protection than smaller, lighter ones," they write, pointing out that even when teens were driving cars, 2 or fewer years old, these tended to be small or mini.
"Newer vehicles generally are also more likely to have better crash test ratings and important safety features such as ESC and side airbags," they say, adding: "Parents may benefit from consumer information about vehicle choices that are both safe and economical."

Dr Timo Wolf and colleagues, from University Hospital Frankfurt in Germany, detail the successful intensive-care treatment the doctor received under biosafety level 4 conditions in an Article published in The Lancet.
On 28 September, 2014, the 38-year old doctor, who was in charge of an Ebola virus treatment unit in Lakka, Sierra Leone, developed a fever and diarrhoea. He tested ...
Prostaglandin analogue eye drops, the most commonly prescribed treatment for glaucoma, can greatly reduce risk of vision loss in people with open angle glaucoma (OAG), one of the leading causes of blindness, according to the first placebo-controlled trial to assess their vision-preserving effect published in The Lancet.
"Medication to lower raised eye pressure has been used for decades as the main treatment for OAG to delay progressive vision loss. But, until now, the extent to which the most frequently prescribed class of pressure-lowering drugs (prostaglandin analogues) ...

Kidney donors with hypertension had slightly fewer nephrons (the kidney's filtering units) at the time of donation than similarly aged donors with normal blood pressure; however, 6 months following their surgery, hypertensive and non-hypertensive donors both maintained excellent blood pressure control and had similarly robust compensatory kidney responses.
Nearly 6,000 people donate a kidney in the United States each year.
Washington, DC (December 18, 2014) -- With proper monitoring, kidney donation may be safe for individuals with high blood pressure, according ...
Struggling to balance on one leg for 20 seconds or longer was linked to an increased risk for small blood vessel damage in the brain and reduced cognitive function in otherwise healthy people with no clinical symptoms, according to new research in the American Heart Association's journal Stroke.
"Our study found that the ability to balance on one leg is an important test for brain health," said Yasuharu Tabara, Ph.D., lead study author and associate professor at the Center for Genomic Medicine at Kyoto University Graduate School of Medicine in Kyoto, Japan. "Individuals ...
WINSTON-SALEM, N.C. - Dec. 18, 2014 - State and local enforcement of federal immigration laws can have an adverse impact on the use of health care services by immigrant Hispanics, according to a North Carolina-based study by Wake Forest Baptist Medical Center researchers.
The study, published in the Dec. 18 issue of the American Journal of Public Health, analyzed both birth records and information collected in focus groups and individual interviews.
"Our findings suggest that immigration enforcement policies negatively affect the health of immigrant Hispanics, including ...
An investigation into factors related to disparities of depression in young adults has found that higher parental education - which has a protective effect for white youth - can also increase the risk of depression for black youth. The MassGeneral Hospital for Children (MGHfC) study published online in the Journal of Pediatrics also found that, among high-socioeconomic-status black youth, greater perceptions of being discriminated against cancelled out the protective effects of parental education.
"High socioeconomic status (SES) - particularly higher parent education ...
Before Charlotte the spider spelled the word "humble" in her web to describe Wilbur the pig, she told Templeton the rat that the word meant "not proud."
That's probably what most people say if you put them on the spot. But if you give them time to think about it deeply, like a new study just did, other themes emerge that have a lot to do with learning.
And these intellectual dimensions of humility describe the spider as well or better than the pig.
"Wilbur has many of the dimensions of humility in general: regard for others, not thinking too highly of himself - but ...
Auroras are the most visible manifestation of the sun's effect on Earth, but many aspects of these spectacular displays are still poorly understood. Thanks to the joint European Space Agency and NASA's Cluster mission combined with data from a past NASA mission called the Imager for Magnetopause-to-Aurora Global Exploration, or IMAGE, a particular type of very high-latitude aurora has now been explained.
Known as a theta aurora -- because seen from above it looks like the Greek letter theta, an oval with a line crossing through the center -- this type of aurora sometimes ...
ITHACA, N.Y. - To encode data, today's computer memory technology uses electric currents - a major limiting factor for reliability and shrinkability, and the source of significant power consumption. If data could instead be encoded without current - for example, by an electric field applied across an insulator - it would require much less energy, and make things like low-power, instant-on computing a ubiquitous reality.
A team at Cornell University led by postdoctoral associate John Heron, who works jointly with Darrell Schlom, professor of Industrial Chemistry in the ...
