Trucks and low bridge underpasses don't mix too well. At least once a week in this city, recently, I've heard of a semi-trailer getting stuck under a bridge.
The obvious way to prevent this (signs don't often work) is to put a lightweight version of the "bridge" over the road, with dangly bits to
smack into the top of the truck and warn the driver. They don't work either, probably because they're not loud enough or they're just not put in place by the road safety authorities, at every underpass, as they should be.
With GPS technology as good as it is now it would be a simple matter of loading a database of underpass heights and locations and having the GPS crosscheck whether the truck will actually fit. A few strategically placed roadside cameras could even measure trucks' heights and transmit them to the GPS, if the driver hadn't entered that data.
Wire it up to the horn and brakes and prevent Joe Lunchbucket ploughing his 50 tonne "traffic scalpel" into a solid concrete barrier at 100 kmh.

We have a number of bridge-tunnels crossing the James River and Chesapeake Bay here. This issue has come up a lot. |
|
| |
They do have trusses across the road with what looks like 2" or 3" metal pipe hanging down on chains. If the top of your truck brushed up against that, I'd expect you to hear it. The trusses are monitored via camera and oversized truck can be culled from the flow of traffice before entering a tunnel. |

When even those measures didn't garner 100% compliance, the state imposed heavy fines for the drivers. I've not heard of a problem since then. |
|
| |
There's a lot of new bridges around here. I suspect that's a large part of the problem. |

There's a bridge near the brewery with a massive chunk out of it, I noted as I passed by there this morning. |

Baked, I'm afraid, in the UK. Link added. |

Plus, instead of requiring companies to buy (potentially expensive)in-cockpit equipment (and subscription to update service), this one works for all vehicles, including the token estate-car-with-sofa-on-roof. |

That doesn't do what my post suggests. It only implements the detection... not the automated control of the vehicle. |
|
| |
Anyway, it's a rare truck that doesn't have GPS nowadays. |
|

OK, half-baked then. This could be linked to a radio or infra-red signal which directly controls the truck in the way you describe. |
|
| |
This same technology could be used on railway crossings if a train approaches. |
|
| |
However could be vulnerable to abuse by whoever wants a truck-stopping remote. Imagine standing on a highway bridge, with a button that can instantly make all nearby trucks sound their horns and jam on the anchors. |

Hilariously disastrous... |
