If you are a cyclist, you will know of the dangers that cars present on the road. Even when you are cycling safely and wearing a helmet, sharp turns and low visibility can lead to disastrous consequences.
If you are a commercial driver of a large truck, any mistake that you make has the capacity to have a more devastating effect than a driver of a passenger vehicle can inflict. This is why you are held to a higher standard when it comes to having alcohol or drugs in your system when driving.
You can blame the heat, the long desolate roads or even the need to work longer hours, but Texans are a tired bunch. There is nothing wrong with being a little tired, but when you decide to drive while being extremely drowsy, the results could be deadly.
