Ignition interlocks have proven effective in preventing intoxicated drivers from starting their car, and now a new system is aiming to do the same for cell-phone users who talk or text behind the wheel.

Consumers have a low level of satisfaction with run-flat tires versus more traditional tires, according to the research firm J.D. Power and Associates. These findings did not surprise us, though they serve as an important reminder for car shoppers who may be more focused on sheetmetal than rubber.

One of the coolest exhibits on display at the huge annual Lifesavers traffic-safety conference in Denver this week is an eye-catching driver-training simulator aimed at teens. Gamifying the education experience, One Simple Decision is programmed to demonstrate the hazards of impaired or distracted driving. And the results are impactful.

In recent weeks, Florida and Texas have crafted proposals to regulate the sale of used tires. Yes, used tires. In this tough economy, buying a used tire at the fraction of the cost of a new one is attractive and may even seem like a reasonable solution for replacing worn-out tires. But it is not.

Six automakers have seen front air bags from supplier Takata blow up in their face, as 3.4 million cars will be recalled worldwide from BMW, General Motors, Honda, Mazda, Nissan, and Toyota. From the headlines, it sounds frightening, with fire and shrapnel being among the risks, but what does it mean to you? We'll explain.

A new service promises the ability for car owners to track their young drivers through a smart phone, receive an alert if preset geographic boundaries are exceeded, conduct maintenance checks, and access an array of convenience features using an Android or Apple device. But, the cool functions come at a price.

The American Academy of Pediatrics recommends that babies born before 37 weeks undergo an assessment called the Infant Car Seat Challenge (ICSC) before discharge from the hospital. This test determines whether a baby is able to safely ride in the semi-reclined position of a car seat. And a new study shows that not all babies are being appropriately screened.

The new Toyota RAV4 is practical, fuel efficient, spacious, and, overall, a really easy car to live with. But there's one thing that is unexpectedly complicated: child seat installations.

Big-rig trailers are required to have underride guards on the back, essentially "bumpers" to prevent cars from running beneath the trailer in a collision. Through rigorous testing, the Insurance Institute for Highway Safety (IIHS) has found that significant risks still exist for passenger-car drivers.

After some mixed results from early models tested in the Insurance Institute for Highway Safety's (IIHS) new small overlap crash test, the latest batch of vehicles earn top scores.

After years of steady declines in teen driver deaths, the fatality numbers have started to increase again, according to a new nation-wide report from the Governors Highway Safety Association (GHSA). The study, which counted up teen driver deaths in every state plus D.C. in the first six months of 2012, found that deaths of 16- and 17-year-old drivers increased from 202 to 240, a 19-percent jump from year-earlier figures.

Over the past two decades, the average age of motorcycle riders has increased, and a new report shows that injury rates have risen at an even greater rate for older riders.

Sharing the road with big trucks scares almost all of us sometimes. You see a semi closing in on your car and worry if the trucker will brake in time, or if they can even see you.

Booster seats are the best way to keep your child safe in the car after he or she outgrows a harnessed child seat but is too small to correctly fit a vehicle's seat belt. The use of any booster seat will improve your child's safety, and likely his comfort as well. Chances are, however, that a high-back booster seat will be better on both fronts than a backless booster. (See our latest booster car seat Ratings.)

If you're thinking you have to run out and buy a new car to get all the latest safety features like lane departure and forward collision warnings, automatic high beam control, and even a speed limit warning, think again.
