Electronic Stability Control

Electronic stability control (ESC) systems combine independent antilock brakes with sensors that monitor steering input and intended line of travel.  When the ESC system senses that a driver is about to lose control, the brakes engage on certain wheels to prevent the vehicle from skidding sideways. 

Preliminary studies indicate that ESC drastically reduces the likelihood of single-vehicle crashes, especially SUV rollovers.  A 2006 NHTSA study found that ESC reduced single-vehicle crashes in passenger cars by 34% and 59% for SUVs.   The rollover prevention statistics are even more encouraging – 71% for passenger cars and 84% for SUVs.  Preventing rollover accidents is the first line of defense in preventing rollover deaths, of which there are more than 10,000 per year.

But that means we depend on the generosity of concerned citizens like you for the resources to fight on behalf of the public interest. If you would like to help us in our fight, click here.
