We know that the trucking industry has expressed concern about potential operational issues which could occur when side guards are installed on large trucks. In order to address those concerns, we asked several trucking companies to give us feedback about their experience after installing side guards on their tractor-trailers.
On April 17, 2020, over 40 people participated in a virtual meeting of a volunteer Underride Protection Committee’s “Side Guard Task Force.” This included two engineers from trailer manufacturers. As a follow-up, several subcommittees began to hold virtual meetings, including an Underride Engineering Subcommittee.
The engineering subcommittee met at least monthly and sometimes every other week from May through November. At the outset, the VP of Engineering of one of the trailer manufacturers provided valuable input. Subcommittee members also participated in a Virtual Briefing for Senate Commerce Committee transportation staffers on August 19, 2020.
The goal of the Underride Engineering Subcommittee was to create a Consensus Side Guard Standard which would provide additional insight for the development of a side guard regulation and industry standard. Lengthy conversation and exchange of information has led this group to submit the following recommendation:
A side underride guard shall be considered to meet the performance standard if it is able to provide vehicle crash compatibility with a midsize car, to prevent intrusion into the occupant survival space, when it is struck at any location, at any angle, and at any speed up to and including 40 mph.
The subcommittee members are in agreement as to the details shaping this long-overdue standard, which they anticipate will lead to the saving of countless lives in the days and years to come. The following group of individuals participated in the Underride Engineering Subcommittee and are willing to continue to provide input.
NOTE: It should be mentioned that this standard has, in fact, been evaluated through research conducted by the Insurance Institute for Highway Safety when they crashed a car at 40 m.p.h. into the side of a tractor-trailer equipped with AngelWings side guards on August 29, 2017, during the Second Underride Roundtable at their Ruckersville, Virginia, testing facility.
There was no underride, no Passenger Compartment Intrusion (PCI), and the crash dummy data showed that it was survivable. In other words, this standard is not pie-in-the-sky; it has been proven that the Consensus Side Guard Standard is attainable.

Authorities have identified 20-year-old Lily Macke of Grimes, Iowa, as the woman who died in a fatal collision between a car and a semi.
The Polk County Sheriff’s Office said in a news release Saturday that Macke was driving a 2006 Nissan southbound on Highway 141 on Friday morning when her vehicle crossed the median and was struck by a northbound semi. Iowa woman killed in collision between car, semi truck
Because the bottom of a truck is higher than the bumper of passenger vehicles, when there is a collision the smaller vehicle easily slides under the truck and the first point of impact is the windshield. Seatbelts, airbags, and car crumple zones do not function as intended in underride crashes —front, side, and rear — leaving passenger vehicle occupants vulnerable to life-threatening injuries.

Emergency crews were called to the scene of the incident on I-465 westbound near Michigan Road at 11:52 p.m. First responders found a full-size cargo van had crashed into the back of a tractor trailer, and two unconscious and unresponsive men were trapped in the van, police said.
Indianapolis Fire Department crews freed the men from the van, but the passenger, identified as 25-year-old Brenden Harper, of Indianapolis, was pronounced dead at the scene. The van’s driver, Andrew Blackwell, 33, of Greenwood, was taken to an area hospital, where he later died. 2 dead after van crashes into semi-tractor trailer stopped on I-465 late Thursday night

Richard Hamm, 62, died when his 2008 Dodge Caliber drove “directly into and underneath” a UPS tractor-trailer in front of Thorlabs at 2:22 p.m. Friday, according to a press release from the Andover Township Police Department. Hamm was traveling northbound toward Newton when the accident occurred, police said.
An investigation determined the tractor-trailer was perpendicular with the roadway and attempting to back into the loading dock area of Thorlabs at the time of the crash. The driver of the UPS vehicle, whom police did not identify in the report, was uninjured.Police identify victim in fatal Route 206 accident involving car, tractor-trailer

William Taylor, 87, of Cochranville, Pennsylvania, died in the crash. . .
the driver of Dodge Dakota was traveling south on Georgetown Road, and for unknown reasons, failed to stop at the posted sign and entered the intersection of South Belmont Road.
The driver of a tractor-trailer was traveling north on the intersection and the front end of the Dodge Dakota collided with the passenger side of the tractor-trailer. The vehicle then became stuck under the tractor-trailer.
The tractor-trailer continued north for a short distance before coming to a final rest in the northbound lane of Georgetown Road.
