Driving in the United States
86 percent of people in the United States use private automobiles as their primary form of transportation to their workplace.
The specific criminal offense is usually called driving under the influence [of alcohol or other drugs] (DUI), and in some states driving while intoxicated (DWI), operating while impaired (OWI), or operating a vehicle under the influence (OVI).
In the United States, the National Highway Traffic Safety Administration (NHTSA) estimates that 17,941 people died in 2006 in alcohol-related collisions, representing 40% of total traffic deaths in the United States.
[17] The arrest rate for alcohol-related offenses among American Indians was more than double that for the total population during 1996, and almost 4 in 10 American Indians held in local jails had been charged with a public order offense, most commonly driving while intoxicated.
[20] NHTSA defines fatal collisions as "alcohol-related" if they believe the driver, a passenger, or non-motorist (such as a pedestrian or pedal cyclist) had a blood alcohol content (BAC) of 0.01 or greater.
NHTSA defines nonfatal collisions as alcohol-related if the accident report indicates evidence of alcohol present.

According to Federal Highway Administration, it states “the color of roadway signs is an important indicator of the information they contain.
A white background indicates a regulatory sign; yellow conveys a general warning message; green shows permitted traffic movements or directional guidance; fluorescent yellow/green indicates pedestrian crossings and school zones; orange is used for warning and guidance in roadway work zones; coral is used for incident management signs; blue indicates road user services, tourist information, and evacuation routes; and brown is for guidance to sites of public recreation or cultural interest.
Traffic regulations are conveyed in signs that are rectangular with the longer direction vertical or square.
The investigation of Eco-driving is consistent with the assessment of accelerating and decelerating under varying traffic and environmental volume and composition.
Using micro-simulation, they analyzed the effects of Eco-Driving on network-wide traffic and environmental performance at the speed of 30 km/h.
Using Eco-Driving under limited speed and control of acceleration and deceleration can possibly affect CO2 emissions.
Carbon monoxide implores the flow of oxygen in the blood to the brain and other body parts.
Sulfur oxides are the cause of acid rain that damages the nature and human health.
Nitrogen oxides are the main ingredients in the formation of acid rain and ground-level ozone that contributes to the global warming.
Finally, high-lead level in the air can damage organs and affect the blood, nerves, brains, and heart.
[30] The U.S. traffic fatality rate fell to 1.08 deaths per 100 million miles traveled for the first half of 2018.
[32] The USA national strategy and target is 6.34 killed per 100 million vehicle kilometers traveled in end 2019.
[34] For tourists, in case of accident it is preferable to call the police (911) rather than to help hurt people, and to stay in that place.
Most states require a motor vehicle owner to carry some minimum level of liability insurance.
In some states you must purchase Personal Injury Protection which covers medical bills, time lost at work, and many other things
