A driver's license is a document that is obligatory for every person that want to drive a motor vehicle on public roads. In the United States, it is issued by the Department of Motor Vehicles (DMV), which is a state agency, and that is why the regulations and laws for obtaining a license may differ from state to state.
However, there are still some common practices in this regard. There is a requirement in every state that a person has to apply for a driver's permit first, before being able to get a license. In order to do that, you first have to pass a written test. The permit is temporary and allows learner drivers to operate motor vehicles, but with certain restrictions. For example, they can drive to and from work and school and may be required to be accompanied by a legal guardian or some other more experienced driver.
After you've had the learner's permit for the required period of time, you may apply for a driver's license. Similar to the learner's permit procedure, you need to fulfill certain requirements as far as a driver's license is concerned. The minimum age limit for a license varies subject to individual state laws, but it's usually not under 16.
At first you must go through a physical examination, as well as an eye examination. Then you have to pass a written test, which is followed by a practical road test.
Typically, there are several different types of driver's licenses, depending on vehicle type and function. In most US states, there is usually a distinction between an unrestricted, restricted, motorcycle and a chauffeur license.
Apart from that, a special license is issued for commercial vehicles, such as buses, trucks and tractors with trailers. Commercial Driver's Licenses (CDL) can have special designations. For example, drivers that operate a vehicle that needs to transport hazardous materials, a tank truck, a semi-trailer or a school bus, they all need to go through some further training as an addition to the standard CDL training.
Getting through the process of acquiring a driver's license can be a little tricky and definitely time consuming. However, you shouldn't lose sleep over it. There are many different laws and procedures in different states, so you need to be well informed and get the necessary paperwork ready before you even think of going to the DMV and starting the whole process.
