Due to the federation character of the United States, it is not possible to cite road traffic regulations across the country. National law regulates only basic issues, and detailed solutions are the responsibility of a particular state.
Differences in the regulations of particular states best reflect the speed limits, which can be very different. In built-up areas (depending on the state) you can move from 18 to 31 mi / h, in front of hospitals, nursing homes, etc. 12-18 mi / h, on exit roads with two-way traffic – 31-46 mi / h, on roads several-lane and expressways – 55-71 mi / h, and on motorways – 50-75 mi / h.
Even greater difference can be seen in the issue of tolerance for drivers under the influence of alcohol. In some states they have to be completely sober – 0.0 ‰, and in others the limit is even 1‰. On the other hand, driving license may be for people over 16 years of age, but they can not carry alcohol up to the age of 21 in the vehicle.
During stoppage, you should stand on the roadside, check the window and wait in the car with your hands resting on the steering wheel. The ticket for road traffic offenses can range from several dozen to several hundred dollars. For exceeding the alcohol limit in the body, you are usually at risk of arrest. In the United States it is possible to turn right at a red light, but after stopping the vehicle and making sure it will be a safe maneuver.
Before embarking on American roads, it is necessary to familiarize yourself with the regulations in force in the states by which we intend to travel. The general Highway Code does not address the most practical issues such as speed limits, alcohol limit, mandatory car equipment, etc.
