Dan Quayle was George H.W. Bush’s running mate. Many people assumed Quayle was incompetent and easily confused, and a newspaper article accused him of looking like “a deer in the headlights” during a debate.

Deer are especially likely to suddenly run into the road during mating season. Bucks are always in pursuit of fawns during the rut.

If the male deer thinks receptive female deer are to be found on the other side of a road, they’ll run across without hesitation.

Deer also cross roads to reach water and food sources. If food and water are in short supply, deer are more likely to suddenly run into the road to find what they can on the other side.

The deer may take a couple of minutes to move, so be patient. As touched on earlier, deer will generally refuse to move until it can see and it will take a couple of minutes for the animal’s eyes to adjust.

As cautious animals, deer won’t move if they don’t know what is happening. They will generally freeze until they can see and ascertain their surroundings.

Always limit your speed as much as possible when driving in areas where they may be deer, especially if it’s near dusk or dawn or at night.
