The transportation industry is constantly evolving, with safety at the forefront of new developments. One of the emerging discussions revolves around side underride guards for semi-truck trailers—a safety feature designed to prevent smaller vehicles from sliding underneath trailers during collisions.

These guards, while not yet mandatory in the United States, have sparked significant debate among safety advocates, legislators, and the trucking industry. As discussions continue, the question arises: Will side underride guards become a required safety feature for trailers in the U.S.? Below, we’ll delve into the purpose of side underride guards, the current state of regulations, and the growing movement pushing for mandatory implementation.

The Purpose and Function of Side Underride Guards

Side underride guards are essential safety devices designed to prevent smaller vehicles from sliding underneath semi-truck trailers during side collisions, a scenario that often leads to severe injuries or fatalities. These guards provide a physical barrier that absorbs impact and redirects the colliding vehicle away from the trailer, significantly reducing the likelihood of a catastrophic outcome.

Tests, including those from the Insurance Institute for Highway Safety (IIHS), have shown that side underride guards could prevent a substantial number of fatal accidents, particularly in urban settings where the risk of side collisions is higher.

By mitigating the severity of these accidents, side underride guards play a crucial role in enhancing road safety, making them a focal point in the ongoing debate over their potential mandatory implementation in the U.S.

Current Regulations and Standards

In the United States, regulations for trailers have focused on rear underride guards, mandatory since the 1950s for most large trucks, to prevent vehicles from sliding underneath trailers during rear-end collisions. However, side underride guards, which could prevent similar risks in side collisions, are not currently required by federal law. This contrasts with countries like Canada and several European nations, where side underride guards are already mandated.

Though the National Highway Traffic Safety Administration (NHTSA) has been researching the effectiveness of side underride guards, there are no federal mandates yet. Some U.S. cities, states, and trucking companies have started adopting these guards voluntarily, but without a national standard, implementation remains inconsistent. The push for federal regulations to require side underride guards is growing, driven by advocacy groups and legislative proposals seeking to enhance trailer safety across the country.

Challenges and Opposition

Despite the safety benefits of side underride guards, their implementation faces several challenges and opposition, primarily due to concerns from the trucking industry. Key points of resistance include:

  • High Implementation Costs: The expense of installing side guards, particularly on older trailers, is a major concern, especially for smaller companies.
  • Impact on Trailer Design: Modifying trailers to accommodate these guards could affect payload capacity, fuel efficiency, and overall logistics, potentially increasing operating costs.
  • Maintenance and Durability: Ongoing maintenance, inspections, and repairs involving side guards for trucks add to the cost and complexity of their implementation.
  • Industry Resistance: The trucking industry generally resists new regulations that could impose financial or operational burdens, favoring voluntary measures instead.
  • Alternative Solutions: Some suggest that other safety technologies or measures might be more effective and less disruptive than mandatory side underride guards.
