Driving demands your constant attention, good judgment, the ability to maintain your vehicle, and a positive attitude.
Some personal health conditions (e.g., poor vision, heart problems, diabetes) may affect your driving. You should discuss your condition with a physician and follow his or her advice when you get behind the wheel. Whether you are calm, nervous, or hot-tempered, your personality affects the way you drive. Extreme emotions of any kind, whether positive or negative, increase the chance that the driver is not paying close attention to the driving scene and the cars around. As a result of your mood, you may also take more driving risks than you normally would when you're calm, relaxed, and alert.
Don't endanger yourself and others on the road by driving under the influence. According to NHTSA statistics the majority of car collisions, injuries, and deaths occur due to drunk driving. In the following section, you can learn about the BAC (blood alcohol concentration), testing for drugs and alcohol, Implied Consent Law, and Zero Tolerance Law for minors, which take place in most of the states.
