What is the speed limit on highways in the United States, and is there a speed limit on highways abr

The speed limit on intercontinental highways in the United States is generally 65 to 80 mph, or 105 to 129 km/h

The highest speed limit is in Texas, with a maximum speed limit of 85 mph, or 136 km/h, on some sections; Speed limits in urban areas range from 50 to 65 miles per hour, or 80 to 105 kilometers per hour. The speed limit in residential areas is generally 25 miles, and if you're driving on a block and don't see a speed limit sign, you're still driving according to that standard.

The speed limit on intercontinental highways in the United States is generally 65 to 80 miles (105 to 129 kilometers).

Speed limits range from 50 to 65 miles (80 to 105 kilometers per hour) near cities.

Let's popularize science. Freeway.

The expressway is a high-grade highway. According to the Technical Standards for Highway Engineering issued by the Ministry of Communications of the People's Republic of China, expressways refer to "highways that can adapt to the annual average day and night passenger car traffic of more than 25,000 vehicles, and are designed for high-speed driving of cars in separate lanes, and all access is controlled". Although the names of expressways vary from country to country, they all refer to highways with more than 4 lanes, two-way separate driving, full control of entrances and exits, and all three-dimensional intersections.

In addition, in many countries, direct trunk lines that partially control entrances and exits and do not use three-dimensional intersections are also called expressways.

In general, motorways can accommodate speeds of 120 km/h or more, and the road surface has a width of more than 4 lanes. A separator is arranged in the middle, and asphalt concrete or cement concrete high-grade pavement is used, and a complete set of signs, markings, signals and lighting devices are provided; It is forbidden for pedestrians and non-motorized vehicles to walk on the road, and to use three-dimensional crossings, pedestrian cross-line bridges or tunnels with other routes. As can be seen from the definition, generally speaking, expressways should meet the following four conditions:

1) Only for high-speed driving; (2) There are multi-lane and first-class separators to completely separate the round-trip traffic; (3) It is equipped with a three-dimensional intersection; (4) The whole line is closed, the entrance and exit are controlled, and only cars are allowed to enter and exit the highway at some specified three-dimensional intersections.

75 miles (but foreigners have a saying that no more than 15% does not count). It is also basically no more than 120 kilometers an hour.

Legal analysis: foreign highways are also subject to speed limits, and their speed limits are generally below 130 km/h.

Legal basis: Road Traffic Safety Law of the People's Republic of China

Article 67 Pedestrians, non-motorized vehicles, tractors, wheeled special mechanical vehicles, articulated passenger cars, full-trailer trailers and other motor vehicles designed for maximum speeds of less than 70 kilometers per hour shall not enter the expressway. The maximum speed indicated by highway speed limit signs shall not exceed 120 kilometers per hour.

Article 68 When a motor vehicle breaks down on a highway, it shall be handled in accordance with the relevant provisions of Article 52 of this Law; However, warning signs should be set up 150 meters away from the direction of the breakdown vehicle, and the occupants of the vehicle should quickly move to the right shoulder or emergency lane, and quickly call the police. If a motor vehicle breaks down or has a traffic accident on the highway and cannot drive normally, it shall be towed and towed by a rescue vehicle or wrecker.

Foreign highways are also subject to speed limits, and their speed limits are generally below 130 km/h. Taking the Netherlands as an example, on November 13, 2019, Dutch Prime Minister Rutte announced that from 2020, the maximum daytime speed on most highways in the Netherlands will be reduced from 130 km/h to 100 km/h in order to control nitrogen emissions.

Under the new rules, the maximum daytime speed on Dutch motorways will be reduced to 100 km/h, the lowest in the European Union with Cyprus. However, between 7 p.m. and 6 a.m., the maximum speed will remain unchanged at 130 km/h.

Foreign.. All I know is that there is basically no speed limit on the highways in Germany. The speed limit is also 250kmh.

The speed limit on intercontinental highways in the United States is generally 65 to 80 mph, or 105 to 129 km/h

The highest speed limit is in Texas, with a maximum speed limit of 85 mph, or 136 km/h, on some sections; Speed limits in urban areas range from 50 mph to 65 mph, or 80 to 105 km/h. The speed limit in residential areas is generally 25 miles, and if you're driving on a block and don't see a speed limit sign, you're still driving according to that standard.

Among them, the only country in the West that does not have a highway such as a speed limit is Germany. Only half of Germany's motorways have no speed limit, while other city roads with speed limits are "proposed speed limits", which can be divided into 80 km h, 100 km h, 120 km h, and 130 km h depending on the situation.

U.S. Highway Mileage:

Since the construction of the first Changwei highway in California in 1937, the United States has built a total of 89,203 kilometers of highways in the country by 1997, accounting for 14% of the total mileage of the country's highways.

Its network runs through almost all cities in the country, and the expressway from New York to Los Angeles is 4,556 kilometers long, making it the longest highway in the world.
