If you travel too closely behind the car in front of you, its tires may fling rocks into your windshield. Do yourself a favor, maintain a safe distance between yourself and other travelers. Finally, if you are traveling slow and holding up traffic, pull over. It is against the law in Alaska to hold up more than five vehicles because of your speed. This is an important thing to remember.
Accidents happen when impatient motorists try passing four and five vehicles at a time.
If you are driving slow, and trying to enjoy the scenery, that's great. Just don't expect everyone else to do the same. Be polite, pull over. Some of us live in Alaska and aren't on vacation. But there are road hazards you should know about.
