But they're getting safer as more car makers add a safety feature called stability control.
Consumer Reports has pushed for this ever since its tests showed the significant difference it can make in preventing accidents.
Wendy Ennis had to replace her old suv after it rolled over on a highway. She says the accident was terrifying.
“Time seemed to slow down and I was sliding on the roof of my car." Wendy said.
David Champion, head of auto testing at Consumer Reports says the risk of an accident like Wendy's can be dramatically reduced with a safety feature called stability control.
If the car starts to slide sideways, it applies a brake to one wheel or more, takes power off the engine, bringing the car back into line, keeping you under control.
Consumer Reports' tests clearly demonstrate the importance of stability control.
With the stability control feature turned on, the same vehicle at the same speed has no problem negotiating this emergency maneuver course.
A recent study by the insurance institute for highway safety reinforces Consumer Reports' findings. The study found stability control can reduce fatal single-vehicle crashes by 56 percent.
And when it comes to suv’s, Consumer Reports says stability control is even more important.
In fact, a new study by the National Highway Traffic Safety Administration finds stability control can reduce single-vehicle suv accidents by 67 percent.
But when looking for a car, it can be difficult to know whether it has stability control because car makers call it many different names.
When you go into the dealer to buy a car, make sure it has in there that it's called stability control and not all-speed traction control, but stability control and then you should have the system that really works.
Knowing how much safer our highway can be, consumer reports says don't buy a vehicle without stability control, especially a suv.
Five automakers announced plans to make stability control a standard feature on their suvs. They are: Ford, Toyota, Honda, Daimler Chrysler and General Motors.
