Roundabouts are circular intersections with design features that promote safe and efficient traffic flow.

Parents choosing a car for their teen driver have a tough decision to make because they need to strike a balance between cost and safety. But the latest analysis by Consumer Reports and the Insurance Institute for Highway Safety shows that more safety is available for the money in the latest list of best used cars for teens.

Most electronic systems that take on some driving tasks for humans don’t adequately make sure drivers are paying attention, and they don’t issue strong enough warnings to make drivers behave.

The agency named 71 vehicles that earned high marks for passenger and pedestrian safety features.

Most small SUVs flunked the latest frontal crash tests done by the insurance industry, but oddly enough, they’re just as safe as they were before.

Drivers of bigger vehicles such as pickup trucks and SUVs are more likely to hit pedestrians while making turns than drivers of cars.

Two organizations that influence many Americans’ automobile buying decisions will begin rating vehicles on how well they track behavior of motorists who use partially automated driver-assist systems.

Two key groups that offer automobile safety ratings have yanked their top endorsements from some Tesla vehicles because the company has stopped using radar on its safety systems.

DETROIT Safety features such as automatic emergency braking and forward collision warnings could prevent more than 40% of crashes in which semis rear-end other vehicles, a new study has found. This is an important countermeasure to that.Trucks with collision warning systems reduced rear crashes by 44%, while automatic emergency braking cut rear crashes by 41%, the study found. For automatic emergency braking, the figure was 12%. In October of 2015, NHTSA began the regulatory process to evaluate forward collision warning and automatic braking for heavy trucks. Some just warn the driver of hazards, while more sophisticated emergency braking systems will actually brake the truck.

The group says that while autonomous vehicles eventually will identify hazards and react faster than humans, and they wont become distracted or drive drunk, stopping the rest of the crashes will be a lot harder. We're still going to see some issues even if autonomous vehicles might react more quickly than humans do. Autonomous vehicles need to not only perceive the world around them perfectly, they need to respond to what's around them as well, she said. Just how many crashes are prevented depends a lot on how autonomous vehicles are programmed, Cicchino said. Even fewer crashes will be prevented while self-driving vehicles are mixed with human driven cars, she said.
