Delays due to trucks striking bridges are a worldwide problem, at least in countries with railroads. Despite yellow black striped reflective panels and height warning signs and sometimes height detectors that trigger flashing red lights.
Perhaps we should try a bale of straw next.
The London Blackwall tunnel has a more modern take on checking height: https://maps.app.goo.gl/b5P5Td1hsuSjLU3w8 traffic signals, barriers like at a railroad crossing, giant panels across the road at height, and a police car on standby to pull out and fine anyone that doesn't read the signs - I presume this happens often enough that they can justify the cost.
But then the bale of straw applied to ships not vehicles and bridges not tunnels.
