Truckmakers Ordered by U.S. to Add Anti-Rollover Technology

Makers of heavy-duty trucks in two years must add electronic stability-control systems to new vehicles, an effort by the U.S. government to prevent rollover crashes that kill about 300 drivers a year and injure 3,000 others.

The technology uses engine torque and computer-controlled braking to help truckers maintain control in emergencies by keeping the wheels on the ground and the trailers from swinging. The regulatory requirement, proposed in 2012, is estimated to cost $585 per truck, the National Highway Traffic Safety Administration said in a statement on Wednesday.
