How do you know when your tired? One of major indicator of when I'm tired is I tend to talk a lot and I'm normally a quiet shy person! I tend to talk about everything under the sun until I annoy people. :lol: ops: :P :twisted: One thing I do to overcome fatigue is to walk around and stretch. Like right now I'm tired and I'm starting yet another pointless topic. :lol:

I know I'm tired when I fight to keep one eye open, while I'm mowing down small sapplings, mailboxes and running opposing cars off the road. What I do is speed up more, as it gives me more steering control, and I get to where I need faster. I sometimes have to use the johnson brake to straighten the trailer out.

My best indicator, is when I stop arguing out loud over imaginary conflicts. :evil:

I know I'm tired when I start thinking that maybe going back to OTR wouldn't be such a bad idea.

I always know I'm too tired to drive when the little guy who lives inside my drivers mirror pops out, taps me on the head and tells me to pull over and get a little sleep.

I know that I am getting tired when I can no longer see. Because my eyes are closed.

Being dehydrated can cause you to be tired also. It's your bodies way of telling you to slow down by making you tired. Drink a few glasses of water and take a walk around the truck. Listening to the news or music will wake you up also.

Your brain is the only thing that needs sleep, the body can go on forever with just food and water. Keeping the brain active will keep you from getting tired.

When your brain gets tired it slows down your breathing in preparation for sleep. The bodies natural reaction to you not breathing enough is to make you yawn and suck in lots more air.

How do I know this? I don't have a clue. Just random useless facts.

How do I know if I'm tired?
My eyes get sore... I start looking and double checking to make sure I didn't miss my exit... Was that light red or green when I went through it... I have to close one eye so that I can only see one road ahead, instead of two... Things like that normally tell me it's time to take a break.

When I start seeing things that are not there I know it is time to pull over and take a nap.
