How to Reduce Bridge Strikes in 2026

Reducing bridge strikes requires addressing several failure points simultaneously. No single intervention eliminates the risk, but a combination of technology, process, and driver training can reduce incidents significantly.

Low Bridge Warning Technology

Camera-based low bridge detection systems scan the road ahead and alert the driver when an approaching structure is identified as a potential height hazard. These systems have improved significantly in recent years — modern versions use AI-powered image recognition to identify bridge warning signs, height restriction markers, and structural features with high accuracy.

The alert gives the driver time to stop or take an alternative route before contact occurs. Systems integrated with GPS can also flag known low bridge locations proactively, providing advance warning well before the hazard is visible.

HGV-Specific Routing

One of the most straightforward interventions is ensuring drivers use routing systems designed for HGVs rather than consumer navigation applications. HGV routing systems incorporate known height and weight restrictions and route around them automatically. The challenge is enforcement — ensuring drivers use compliant navigation rather than defaulting to familiar apps.

Pre-Trip Checks and Training

A non-trivial proportion of bridge strikes involve drivers who don't know the height of the vehicle they're driving. Systematic pre-trip height checks and driver training that makes height awareness habitual reduces this category of incident significantly.

Operator Responsibility

Fleet operators carry a legal responsibility for bridge strike incidents. Operators who can demonstrate that they have deployed available technology and implemented appropriate training and process controls are in a materially better position when incidents do occur.
