Saw this in the Accidents in India thread. Made me think of the importance of under-run protection instantly:

Construction:

Even a difference of a few inches in the construction can lead to a much weaker under-ride bar.

In this example the placement of the car, the car's speed, and the bar's length & material are all exactly the same in both tests. But, spot the difference in crash results:

Answer: The under-ride bar on the right has the vertical members much closer to the center of the truck. They should be further out to give the ends of the horizontal bar more strength.

Unfortunately this is a common problem with the construction of bars on Indian trucks.


Another downside:

In the US, the bars are only tested till 35 MPH (56 km/h). There's no guarantees above that speed...

Just look at the way that Innova has crumpled. It's high time authorities should start checking under run protection bars on trucks strictly. No car is designed to take such a high impact on the A Pillar.

I am surprised to see the overhang the truck has. The rear overhang could accommodate the whole Innova (not at all happy to see this) and the Innova hasn't even reached the rear axle.

A smaller overhang could have minimized the damage in this case. I know that is not the ideal solution here but just a thought.
