Low Bridge Detection System

Bridge strikes remain one of the most common and disruptive incidents affecting commercial vehicle operators across the UK. Motormax’s Low Bridge Detection System provides advanced height-clearance monitoring and proactive driver alerts, helping fleets avoid costly collisions with low bridges, overhead structures and restricted routes.

The system automatically identifies potential height conflicts and delivers clear visual and audible warnings, allowing drivers to take action before an incident occurs.

Bridge Strikes Continue to Impact UK Transport Networks

According to Network Rail, there were 1,666 bridge strike incidents across the UK between 1 April 2024 and 31 March 2025, the equivalent of one incident every five hours.

These incidents can result in:

• Vehicle damage and repair costs
• Road closures and traffic disruption
• Rail delays and infrastructure repairs
• Increased insurance claims
• Reputational damage to fleet operators

Many bridge strikes occur simply because drivers are unaware of their vehicle’s height or encounter unexpected route restrictions. Read more about bridge strike prevention in our insights blog.

How the Low Bridge Detection System Works

The Motormax Low Bridge Detection System continuously monitors vehicle height against known bridge and overhead structure clearances using AI technology, GPS mapping, or a combination of both. Vehicle height is configured during installation, ensuring reliable and accurate monitoring without requiring driver input.

When a potential height conflict is detected, the driver receives:

• Visual in-cab warning
• Audible driver alert
• Real-time event recording via MaxConnex®
• View our Low Bridge Detection System on our trade website
