No one has suggested retractable spike strips? They could auto-engage when they detect an over height vehicle and nearly instantly take 6-8" off of the height of an oncoming truck.
I mean, it would cause a lot of destruction, but the being would be less likely to be hit…
Notice how bridge signs are always in 3 inch increments?
The advice is give yourself a good six inches.
Most men can’t be trusted with that measurement
And also a sobering read:
Ok so you have knackered the bridge, blocked the traffic, ruined everyones day, and away you go with a slap on the wrist.
No, Network Rail and the Traffic Commissioners are thoroughly fed up with this, and so hitting a bridge is a one way ticket to a Public Inquiry. Guaranteed
Consequences for the driver involved are likely to be a minimum 6 month suspension of the vocational driving licence.
For the Operator (company running the lorry) it may well mean the revocation of their Operator’s licence. Which means the end of the business.
Stick the stargate on the train tracks. In the dailout time (15 minutes?) they could move a lot of freight. (Only usable to sites with matching tracks, of course.) None of this fiddling around with people running up a ramp.
