Bridge Strikes Reported in the Past Year

Issue

In the UK, more than 1,800 bridge strikes are reported every year. These incidents are far more than a minor inconvenience—they cause significant disruption to road and rail services, damage infrastructure, and lead to costly repairs, delays, and liability claims. For fleet operators, just one bridge strike can mean thousands of pounds in losses, not to mention the impact on driver safety and brand reputation.

Despite improved signage and awareness campaigns, bridge strikes remain a persistent issue. Drivers are often unaware of their vehicle’s exact height—particularly in leased or changing fleets—and may miss low bridge warning signs or rely on outdated satnav information. In fast-paced operating environments, where routes change frequently and pressure to stay on schedule is high, even experienced drivers can make critical errors. Factors like poor weather, low visibility, and unfamiliar roads only increase the risk.

Solution

ACSS Low Bridge Warning System is an advanced, AI-powered safety solution designed to help drivers avoid low-clearance collisions before they occur. Using a combination of GPS positioning and AI-enhanced dash cameras, the system delivers real-time in-cab alerts whenever a vehicle approaches a low bridge.

Our technology references a verified database of over 2,000 low bridges across the UK and dynamically calculates clearance using AI vision to read road signage and gantries. This dual-layer detection ensures drivers are given timely, accurate alerts, reducing reliance on memory or guesswork and helping them make safe decisions on the road.

The system also includes a suite of advanced driver assistance features, such as forward collision warnings and monitoring of safe following distance, enhancing road safety beyond bridge strike prevention. It operates as a standalone unit or can be integrated with AC Cloud, our powerful video telematics platform, allowing fleet managers to monitor alerts, review incident footage, and generate compliance reports remotely.
