Is there a problem?

Federal law requires large trucks to have rear underride guards but not side underride guards. At least three U.S. cities, Boston, New York and Seattle — mandate side guards on city-owned and/or contracted trucks as part of Vision Zero initiatives to eliminate crash deaths and injuries, particularly among pedestrians and bicyclists.

Watch the full compilation video of the side underride test held at the IIHS testing facilities.

The immense size and weight of large transport trucks can result in devastating results for a passenger vehicle and its occupants should a underride collision occur.  According to NHTSA data, 73% of all fatalities in a truck accident in 2014 were the occupants of other vehicles.  In 2015, White House and DOT issue call to action to data scientists and public health experts as 2,348 more people died in crashes than in 2014.

As the number of truck crashes and the resulting injuries and fatalities continue to rise, addressing truck safety issues is integral to making our highways safe again. In 2015, 4,067 people were killed in crashes involving large trucks, representing a 20 percent increase from 2009. This is the first time truck crash deaths have exceeded 4,000 since 2008. Further, early release data for 2015 shows that there were 415,000 truck crashes, which resulted in 116,000 people injured in crashes involving large trucks — an increase of 45 and 57 percent since 2009, respectively. The annual cost to society from crashes involving commercial motor vehicles is estimated to be over $110 billion.

What is a side, rear or front underride crash?

Few truck accidents are more destructive than those that involve a passenger car which gets lodged or pinned underneath a large transport truck. The tractor trailer bed is often higher than the hood of a standard vehicle which when a side, front or rear underride crash occurs, the car goes partially or completely under a truck or trailer. This significantly increases the chance of severe injury or death as most safety accessories and devices like airbags, anti-avoidance technology, and other type equipment are rendered ineffective because of the difference in heights between transport trucks and regular passenger vehicles.

What can be done to prevent this type of accident?

Recent IIHS tests evaluated a side underride guard crash at 35-mph.  One test crash involved a mid-sized vehicle and a semi-trailer outfitted with a typical composite side fairing side skirt intended only to improve aerodynamics.  The second test involved a mid-sized vehicle and a semi-trailer outfitted with a typical composite side fairing skirt and a side underride protection devices (AngelWing).  Although the crash specifications were similar (trailer, speed and vehicle type), the results were dramatically different.

In both tests, a midsize car struck the center of a 53-foot-long dry van trailer. In the AngelWing test, the underride guard bent but didn’t allow the car to go underneath or strike the trailer.  The end result was that the vehicle’s safety devices (air bags, safety belt, and crumple zones) could properly restrain the test dummy located in the driver seat. In the second test, with only the side fairing skirt and no side underride protection device, the car traveled underneath the trailer, slammed into the windshield and impacted the side of the trailer.  If the semi-trailer was in motion, the car could have possibly flipped the trailer, come into contact with the rear wheels, or both risking the life or the semi-trailer occupants as well.

The resulting impact sheared off part of the roof, and the vehicle became wedged beneath the trailer. In a real-world crash like this, any occupants in the car would likely sustain fatal injuries.

In summary, trailer fairing skirts are specifically designed to control the flow of air underneath the semi-trailers and reduce fuel consumption and not engage safety features of vehicles such as airbags, crumple zones or anti-avoidance technology (if equipped).  Should an impact occur, the car will breach the skirt and travel underneath the trailer and passenger compartment intrusion (“PCI”) will occur, possibly causing life-altering injuries or death.

How do AngelWing Truck Side Guards work?

AngelWing Side Underride Protection Devices are attached directly to the cross member of the semi-trailer body at specified intervals.  The strength of the lateral protection is achieved by AirFlow Defector’s patent pending skeleton design.  Upon impact, AngelWings dynamic structure engages and deploys the vehicle’s built-in safety features such as airbags, anti-avoidance sensors, crumple zones or seat belts, designed to protect its occupants from possible injury or death.

The end result is that AngelWing side underride protection devices provide strength, safety, and security to the affected occupants as well as underride protection to vehicles which may come into contact with the side of trailers.

Do I need to replace my side fairing skirt?

No, AngelWIng SideTruck Side Guards are designed to integrate with most composite side fairing skirts.  We work with most truck semi-trailer skirt companies so that both safety, security and fuel efficiency can be achieved.  Please contact your dealership for further details.

Fuel Saving Under-mount Deflector

AirFlow Deflector LTS Devices – SmartWay Certified

Designed to provide incredible fuel savings and stabilization while driving. LTS Deflectors are aerodynamic under-mount devices that reduce wind resistance and increase fuel efficiencies while providing better tracking properties when compared to traditional fairing truck skirts.

Created using the same objective as F1 race cars, our deflectors converts trailers and heavy trucks into aerodynamic vehicles. By redirecting air around the axle reduces turbulence and provides considerable fuel savings. It absorbs and deflects the wind to the side of the trailer and consequently increases the stability of the vehicle which contributes to up to 8.5% of fuel savings.  SmartWay certified providing confidence that they will produce results.

LTS Deflectors protect the rear axle from the ravages of bad weather and reduces the wear effect on the vehicle, extending the service life and reducing maintenance costs.  LTS guards are US patented and qualified with the SAE J1321 Type II. AirFlow products are easy to maintain, to install and is compatible with most trailers and trucks including flatdeck.

AirFlow Deflector’s goal is to increase fuel savings providing a more green approach to transporting goods as well as ensure the safety of your streets. LTS deflectors are EPA SmartWay Verified Technologies for Advances Trailer Aerodynamics as well as by the California Environmental Protection Agency.

Airflow Deflector LTS devices are eligible for a subsidy by many government agencies including the Hunts Point Clean Truck Program (www.huntspointctp.com) and the 30% rebate offered through Transport Quebec.
