We can never really say it enough: always make sure you're not too tired to drive. As the dashcam footage featured here shows, even being a little tired can lead to disaster. The driver mistakenly thought the car ahead of him was too close, so he hit the breaks and his vehicle went out of control. Eventually, the car did come to a stop, but not before causing some damage to the car and knocking down a tree.
Next, a guy and his brother-in-law in Texas were on their way home when the brother-in-law took the car out of four-wheel drive while they were still on an icy road, which ended up being a mistake. The car slid across the road and almost collided with a railway crossing post. Fortunately, everyone was OK.
