| If you experience any of these Warning Signs get off the road immediately: |
 | You find yourself weaving in your lane or drifting into other lanes; |
| Your eyes start to play tricks on you, e.g. a motorway off-ramp looks like your lane; |
| Or a road sign looks like a person standing on the side of the road; |
| Your vision becomes blurry; |
| You lose mental focus and become unable to concentrate for more than a few seconds; |
| Your eyelids become heavy or difficult to keep open and they close by themselves; |
| Your head nods or falls toward your chest; |
| You become drowsy or overly relaxed. |
