Why Are Rear-End Collisions into Trucks So Deadly? The Back Guard Series Offers an Engineering Solution

Rear-end collisions between small passenger vehicles and large trucks are a common yet often devastating type of accident on roads today. Due to the high ground clearance at the rear of most trucks, small vehicles tend to slide underneath the truck bed during a crash—a phenomenon known as "underride." This often results in severe deformation of the passenger cabin and, tragically, driver or passenger fatalities. Reducing the harm caused by such accidents has become a critical challenge in commercial vehicle safety.

In response to this industry-wide issue, Shanghai Riminghuan Trading Company Limited has developed the Back Guard Series Rear Underride Protection Device—an engineering solution that combines structural integrity, energy absorption, and ease of installation.

Industry Background: Underride Accidents Demand Better Passive Safety

Statistics show that in rear-end collisions involving a small car and a medium-to-heavy truck, the fatality rate is significantly higher when underride occurs. The primary reason is that many trucks have high rear ground clearance, and their rear underride protection devices are either insufficient in strength or completely absent, preventing the car’s crumple zone from functioning effectively.

In recent years, many countries and regions have introduced mandatory standards for rear underride protection devices on trucks. However, structures that merely meet minimum regulatory requirements often fail to protect the following vehicle in real-world crashes. The industry is now shifting from simple "compliance" to "effective protection," and the Back Guard Series is designed precisely for this evolving need.

Product Technical Highlights: Energy Absorption, Safety, and Customization

1. Non-Destructive Installation, Compatible with Existing Vehicle Structures

The Back Guard Series can be mounted based on the original vehicle structure without cutting or welding, preserving the vehicle’s integrity and lowering installation barriers.

2. Multiple Models for Different Applications

Three versions are available: Temperature-type, Fixed-type, and Retractable-type. These are designed for 2–4 ton vehicles across various wheelbases, load capacities, and operating conditions. Clear installation dimensions and weight parameters are provided for easy engineering matching.

3. Built-in Metal Energy-Absorbing Structure Prevents Secondary Accidents

Unlike ordinary rubber or simple steel guards, this device uses impact-absorbing metal profiles. In the event of a collision, it effectively absorbs impact energy without generating sparks or shrapnel, reducing the risk of fire and secondary incidents.

4. Effective Even in Offset Rear-End Collisions

The design accounts for both direct and offset impacts. Even if the following vehicle strikes from an angle, the device still provides protection, increasing real-world accident coverage.

5. Highly Visible Reflective Warning Strip

The device is equipped with a red reflective warning strip, improving visibility at night or in low-light conditions. This feature combines active and passive safety by alerting following drivers to maintain a safe distance.

Typical Applications

• Urban delivery trucks (box trucks, flatbed trucks)

• Sanitation and construction vehicles (at risk even at low speeds)

• Light commercial vehicle fleets (most suitable for the 2–4 ton category)

• Cross-border transport vehicles (meeting higher underride protection standards across different markets)

Services and Support

Shanghai Riminghuan not only designs and manufactures the product but also offers customized color options and structural adaptations. After-sale replacement services are available. Whether for single-vehicle installation or fleet-wide deployment, customers receive full technical support.

Conclusion

As commercial vehicle safety standards continue to rise, underride accidents remain a serious and often overlooked risk. The Back Guard Series is more than a simple structural add-on—it is an engineered, energy-absorbing rear underride protection solution. More than just a product, it represents a tangible commitment to protecting the lives of all road users.
