Automatic Emergency Braking

In 2015, 4,067 people were killed in large truck crashes in the United States

Automatic Emergency Braking

Automatic Emergency Braking (AEB) technology is a proven highway safety technology that could and will save countless lives and prevent injuries.  Unfortunately, after years of study and successful use by leading motor carriers, this technology has yet to be required for commercial motor vehicles.  As the public endures continued delays to require equipment that is readily available, families across the nation have had to pay the ultimate price.
In order to prevent these needless deaths and injuries, the National Highway Traffic Safety Administration (NHTSA) should mandate AEB technology on all large trucks with a gross vehicle weight rating of 10,000 pounds or more. While the agency granted the petition submitted on February 19, 2015 by the Truck Safety Coalition, Road Safe America, Advocates for Highway and Auto Safety, Center for Auto Safety this past October, action is long overdue and we call on NHTSA to produce a final rule.
NHTSA estimates that current generation AEB systems can prevent more than 2,500 crashes each year and that future generation systems could prevent more than 6,300 crashes annually. Every year a full implementation of AEB is delayed, research estimates that 166 people will unnecessarily die and another 8,000 individuals will suffer serious injuries. In a September 2018 study, the NHTSA found that AEB systems have an incremental cost to the end user of $70.80-$316.18.
To save these lives, prevent injuries, reduce costs, and ensure families remain whole, we call on Congress to immediately mandate AEB technology in all large trucks by passing H.R. 3773, the Safe Roads Act. To get involved in this effort, we invite you to send a message to your Senators and Representative to educate them about the benefits of requiring this technology in the heaviest vehicles on our roads.

Automatic Emergency Braking – Prime Time for Regulation

From the Truck Safety Coalition… Semi Crashes in Kansas Work Zone

A highway worker was providing traffic control with an arrow board in the back of a pick-up truck when he was struck by the truck. The semi sideswiped the truck and then rolled onto its side. Fortunately, no one was injured in this crash.

We wanted to bring your attention to this crash because it is National Work Zone Awareness Week. Even though large trucks constitute 5 percent of the registered vehicles in the U.S., 30 percent of fatal work zone crashes involve a large truck. Too many work zone crashes occur because the truck driver cannot stop his/her vehicle in time, which is why TSC promotes collision avoidance and automatic braking on large trucks.

From the Truck Safety Coalition … 1 Killed, 1 Injured in Michigan Work Zone Truck Crash

In Michigan, two road workers were installing a highway sign at 5 p.m when a they were struck by a truck. The big rig crossed the white fog line into the work zone, killing one of the workers and injuring the other. The semi-truck driver was charged with reckless driving causing a death.

It is National Work Zone Awareness Week, and this fatal and injurious crash serves as a grave reminder that more must be done to ensure safety on our roads for the men and women that help fix and build them. Large trucks are involved in 30 percent of all fatal work zone crashes. TSC will continue supporting a federal mandate for forward collision avoidance mitigation braking on large trucks, and continue opposing efforts to allow Double 33s, which have a 22 foot longer stopping distance that existing double (28-foot) tractor trailers.

From the Truck Safety Coalition… 10 Year Old Girl Survives After She Was Hit by a Box Truck

After stepping off of the school bus and crossing the street, 10 year old, Olivia Walter, was struck by a box truck. Despite another motorist stopping and waving her to cross the street, a box truck that was approaching from the other lane hit her on the right side. The girl sustained a fractured bone above her eye and bruises and road rash on the right side of her body. TSC supports collision avoidance technologies that require automatic braking, which may have prevented this truck from hitting this girl.

From the Truck Safety Coalition… Teacher Dies in Tragic North Carolina Crash

Last week, a dump truck towing a Bobcat bulldozer rear ended a minivan, causing it to collide into a tractor in front of it. Consequently, the minivan was destroyed and a 42 year-old high school English teacher was killed.

Unfortunately, this fatal crash could have prevented by commonsense proposals that TSC has been promoting for years. Adopting forward collision avoidance and mitigation (F-CAM) technology could have prevented this crash, or at least mitigated the severity of it. Establishing a drug clearinghouse database would have also possibly prevented the crash. The driver of the dump truck, who had a history of driving violations as well as two pending drug charges, should not have been behind the wheel of this truck.

From the Truck Safety Coalition… Crash Avoidance Technologies May Have Saved Lives in ME Truck Crash

Two people were killed in Knox County, Maine last week after a tractor-trailer crossed the center line, corrected, fishtailed, rolled, and then took out four cars. It is still unclear as to what caused the driver cross lanes and overcorrect, but this is consistent with issues such as fatigue and distracted driving. Technologies like electronic stability control, lane departure warnings, and forward collision avoidance and mitigation braking systems would reduce the chances of these truck crashes as well as the severity of a crash. TSC will continue our education efforts with Members of Congress on the need to mandate these proven technologies.
