Truck vs. footbridge
Checking your mirrors is one of the fundamental requirements of the UK driving test, and this video shows exactly why it is so important.
OK, occasionally you might neglect to check your rear-view when you are heading down the motorway, but surely this truck driver must have noticed something was amiss.
What is also shocking is what happens when the inevitable happens and he collides with the bridge. Thankfully no-one was seriously hurt as far as we are aware.
