This is why a good grasp of number sense is important.
The trucker didn't know that her 43,000 pound load plus the weight of her truck exceeded 6 tons.
The trucker did not realize that the height of her vehicle exceeded the height of the bridge.
What a great example of the importance of math in the everyday world.
The police report is interesting.
