At the wheel

At the(And) (a)sleep at the wheel. The stunning video tonight (of the) bus driver who nods off and then smashes into car after car. Next tonight, bus driver who falls (asleep)at the wheel as cameras roll. ABC's Linsey Davis now on the multiple collisions. It happened last October around 6 p.m. it was olympia michigan (in Wes Bloomfield, Michigan). The driver quickly admitting to investigaters what went wrong. What happened? I fell asleep going down that hill. Sleepy drivers are to blame (for)one out of every five car accidents killing 7500 people seriously injuring 50000 each year. As for the solo(e) passenger on the bus. Are you alright? I sure I am, I think so. Her choice of seat on this day may have made all the difference.

When I go to KGU, I often use my bicycle, listening to English podcast. Riding bicycle makes me feel comfortable. But, during the period of exams for each semester, due to a large amount of reports and tests, I stay up late almost every nights. So, as I have feeling of sleepiness and fatigue that period of time, I have no choice but to use my car. 

Once I didn't get any sleep two days, on the way to the university, I fell asleep temporarily many times at the wheel. A catastrophic car accident may have happened if I had steered in the wrong direction.
