Err, they're not going through the tunnel. They're too tall for it. They crash into the roof of the tunnel, causing severe damage to the infrastructure, their trucks and anyone who happens to pass by.

There's likely some space left between actual tunnel height and truck height limitation (for safety), and clever driver's incentive to go through the tunnel (if it's a nice shortcut) might be stronger than any kind of sign.

If you deliberately put yourself in a situation where you're operating a machine without the mental faculties you need to do it safely, then I think we can safely say that you deliberately caused the accident, even though you may not have thought, in so many words, "I think I'll go cause an accident now."

People are probably more afraid of losing their jobs. They also probably think it won't happen to them.

Well, if people are deliberately endagering lives of others for fear of losing their jobs; then maybe we should ensure that they'll fear the legal consequences more than their boss?

For example, if you temporarily take away the truck drivers licence as a punishment for driving too many hours without rest (as EU does, for example), then they'll make sure that they don't drive without rest, since they will definitely lose their driving jobs if they do.

I'm mildly surprised that requiring trucks to file travel plans has not become a more widespread practice. What with terrorism concerns, and the widespread use of GPS monitors on trucks it's both feasible and plausible. It seems like major metro areas could institute a slightly tighter control of large load vehicles; which could actually benefit from coordinating with traffic control signals in some cases.

Since Garmins and other GPS devices have lane information and speed limit information, you'd think you could punch in your load height and get a route that worked for it. Anyone want to go collect 500K bridge heights for the database?

In the US at least the state DOT's have that information and have a GIS office that would make it available for a nominal fee. You'd still need to check a lot it in cities. Big worry would probably be liability; if your database of overpasses has an error (inevitable) can the truckers insurance company hold you financially responsible for relying on your app?

Unfortunately when we have reliable, safe, self-driving cars, the loudest complainers will be truck drivers who now have to find new careers. I hope I don't sound too mean to hope their concerns are ignored.

If we make long-haul trucks self-driving, then we'll just have to replace the 'driver' job with 'guard' job. Otherwise it's far too simple - block the road; the robot will stop to avoid an accident, and you loot the cargo and/or the car. It doesn't really matter what they're shipping - a truckload of TVs is nice, but even a truckload of sh*t is valuable enough to make it worthwhile.

That's fine as long as they don't kill people by driving while fatigued

Garmin already offers a specific product line for truckers and bus drivers, that deals with these kinds of issues - beyond vertical clearance you have issues of turning radius and maximum load.

I've seen them being sold at major truck stops in the US. You're not suppose to use a normal consumer GPS if you're driving an oversize / multi-axle vehicle.

Why not have a plastic flap hang down and thwack the top of the too-tall truck? Next, if that's ignored, a plywood barricade hanging down: Better some splintered plywood than a jammed tunnel.

And lastly a large flashing sign, or water sign, saying there is tire damage up ahead. Then have tire damage spikes come out of the road. It's the drivers responsibility to not damage the tunnel or bridge. Better to damage some cheap tires on a truck than the tunnel.

A vehicle with its tires blown will take longer to stop than one with its tires intact and brakes applied. This would just turn it into an 40-ton wrecking ball - what if there's stopped traffic in the tunnel?

This is the same problem as getting pilots to not land on aircraft carriers with their landing gear up. I've heard they station a guy with a flare gun as a final notification, but sometimes the pilot lands anyhow.

This idea could be used on an aircraft carrier, if the water was sprayed up from below.

I think it would be interesting to try a projection of a scary face, or even a non-scary face, or a video of a crowd of people.

Really? "any vehicle size"? Including trucks carrying around 40ft tall construction equipment (like cranes) on flatbeds? What about those huge wind-turbine pieces? You can't plan for "any", especially with shrinking government budgets globally. You plan for "most", and work to ensure the remainder has some sort of possible route.

I knew somebody was going to point out that oversized vehicles won't fit. For your knowledge, these vehicles are not normally legal to drive(in the EU), they need to have special permissions, display "oversized" badge on the back and on the front, but most importantly, they need to have their route planned and approved days in advance from actually driving anywhere. So none of these vehicles would ever crash into a t…

Cool, clearly Australia is a bit different.

Can you, maybe, also cite a trustworthy source on how many trucks actually went through the tunnel without a problem? I imagine there're clever drivers who know precisely metrics of their vehicle and tunnel regulations. I think we rarely hear about those cases on the news, though.

Edit: if you're responding “No” to whether there's leeway between actual tunnel height and regulations, I'd like to hear a source on that as well—I couldn't find one, but common sense suggests that in such a case then there'd be enough incidents of trucks with allowed height damaged because of, say, a bump on the road.
