Raising the bridge always was the only real solution.

Yep. Electronics was used in the most effective way - to put so many embarrassing videos of crashes on the internet, that the authorities eventually had to fix the height of the bridge.

The extra 8" will help, and will prevent some crashes, but it isn't enough to stop them all.  :)

There will still be ripped-open trucks and toppled equipment, but it will be less frequent now...

Id bet, if you pulled each driver after a crash, and asked them “ how many inches in a foot “, half of them would go blank.
It’s a basic question of driver confidence and competence.
Don't ask a question if you aren't willing to listen to the answer.

Don't forget context. People have different size feet, you know, and most of them are shorter than ‎0.3048 meters.

I'm actually kinda curious, do big trucks, especially rentals, give you any info on their height?  Like is it listed on the dash somewhere?  I feel that could actually solve a lot of these issues.  Most people see the "clearance" sign and assume they'll fit but don't actually know their vehicle height.

I've rented a truck in Sydney a couple of times - and they DO advise you of the height... VERY CLEARLY.  They also make the point that the insurance cover option they provide does NOT include damage caused by over-height impact.

What they don't do - and CAN'T do - is get the driver (used to their highest point being a foot above their head) to appreciate that the highest point of the vehicle they're driving is now four feet (or more) above their head.

I'm not just talking about standing outside and looking up - I'm talking about when they are driving along, paying attention on navigation, lane changing and generally avoiding collision with non truck friendly traffic when their thoughts on the structure towering above their head is not featuring in their thinking.  This is not to mention their lack of interest in height warning signs - because they've never needed to worry about them before.

A number of the rental trucks I have seen in the past 3 years tend to have stickers somewhere near the rego sticker saying the height and gross? weight of the vehicle,

Haven't all large trucks been marked with their height and gross weight for decades, by mandate?

on the outside, yes, but rarely do they put it in an at a glance location you would find when you suddenly see "Low bridge ahead" or a road weight limit.

Whenever I have rented a box truck in USA, the vehicle height has always been printed on the dash, and usually on or near the driver door on the outside, and sometimes on the back of the truck, too. And as others have said, they make sure they tell you, too, and it’s a big bold point on the contract that height damage isn’t covered by the insurance. You have to be a real idiot to not know the height. Whether you do anything with that information is an altogether different matter.

In my experience, they also have it printed, mirrored, on the front corners of the box where it is clearly visible and readable when seen in the rear view mirrors.  There is also a sticker or printing on the dash REMINDING the driver that the vehicle is very tall, and that they must be aware of clearances when driving under things.

Good to know, sounds like most of these cases are definitely user error then.  I was ready to give benefit of doubt as someone who drives a normal size vehicle never even bats an eye at height signs as they only apply to large vehicles, then suddenly you're renting a large vehicle and I could see it slip the mind.  But if it's clearly printed, and told at the point of rental then yeah, no excuse really. 

Of course you not only need to know your height, but the height of your cargo.  If you are loading a vehicle with cargo that is higher than the vehicle then you should be aware of that.

Definitely user error.  If you have ever rented a box truck or RV (caravan) you know there is no way you can forget you are not driving a normal passenger vehicle.  Sight lines, turning radius, acceleration, braking, noise and comfort are all dramatically different.  In addition to all of those written warnings.

You certainly wouldn't forget, but all the cognitive load of coping with all those differences might reduce the amount of brainpower available to think "I wonder if I'll fit under there?".

Lasers.  Powerful lasers.  That will solve the problem.

Would these be used to slice off any excessive vertical areas of the approaching vehicles?

One obvious solution would be to remove the bridge altogether.
Or the road that passes under it.

Maybe if the signs had said it only had 3.5m clearance people wouldn't have run into it so much!

Anyway, raising it by 200mm seems to have solved the problem. ;D

Yes maybe. Could have it helped to also give a clearance figure in feet? :-DD (Sorry that was just because of the other thread...)

It solved the problem of the 11' 8" bridge - but now we have the new problem of the 12' 4" bridge.

Add a very slow speed limit like 20mph at least 1000 ft away from the bridge. This will give the truckers enough time to slow down and read the sign.

Easier idea: paint the whole area yellow and black stripe.  The bridge, supports, earth banks, road - everything.

No - scratch that.  Just paint it all a bright shade of pink.
