Driving in the U.S. can be confusing not just because of all the rules and laws that drivers must follow, but also because of driving customs. Many people in the U.S. are really dependent on their cars to get to work and school. In fact most American workers spend an hour driving to work each day. In order to drive in the U.S., you have to go to your local Department of Motor Vehicles first, and take a written test to get your learner's permit. If you pass this test, you can practice driving so you can pass a road test and get your license. The Department of Motor Vehicles or DMV has free booklets you can go and get to study for your learner's permit. You can also access the information online and even take a practice written exam. To prepare for the road test, you can have a friend teach you to drive or pay to take classes at a driving school. You cannot, however, practice driving by yourself. If you are caught driving with only a learner's permit, you can get into trouble with the law.
Once you get your driver's license in one state, you can use it to drive in all of the United States. Wherever you drive, you will see signs posted along the road indicating the speed limit. These numbers are not a suggestion. Generally you can drive faster on a highway than on local streets. Local police use special equipment to detect your speed. If they detect you are speeding or driving over the speed limit, police can stop you and give you a ticket. You will have to pay a fine, and some of the fines are more than $100. The lines painted on the road are not just to keep cars in their lanes. They send a message. For example, a double solid yellow line means that it is against the law to pass another car here.
