美国的交通规则有哪些,用英文表达？

In the United States, there are various traffic rules that should be followed. Some of the key rules include: 1. Driving on the right-hand side of the road: In the U.S., vehicles are driven on the right-hand side of the road. This helps to ensure uniformity and maintain order on the roads. 2. Speed limits: Each state and municipality in the U.S. has its own set of speed limits, which drivers must adhere to. These limits are typically indicated by speed limit signs placed along the roadside. 3. Traffic signals: Traffic signals such as red, yellow, and green lights are used at intersections to regulate the flow of traffic. Drivers must obey these signals and come to a complete stop at a red light before proceeding when it turns green. 4. Stop signs: Stop signs are used to indicate that a driver must come to a complete stop at an intersection. Vehicles should only proceed when it is safe to do so, after yielding to any traffic that has the right of way. 5. Right of way: The right of way determines who has priority when multiple vehicles approach an intersection or other driving situations. Generally, vehicles must yield to pedestrians and follow the right of way rules to prevent accidents. 6. Seat belts: Seat belt use is mandatory in the U.S. for both drivers and passengers. It is essential for safety and failure to comply with this rule can result in fines or penalties. 7. No drinking and driving: Driving under the influence of alcohol or drugs is strictly prohibited. The legal blood alcohol concentration (BAC) limit in most states is 0.08%. Violating this rule can lead to severe legal consequences. 8. Yielding to emergency vehicles: When emergency vehicles such as ambulances, fire trucks, or police cars approach with their lights and sirens on, it is mandatory to yield the right of way and move to the side of the road to allow them to pass. It is important to remember that traffic rules can vary slightly between different states in the U.S. It is advisable for drivers to familiarize themselves with the specific rules and regulations of the state they are driving in to ensure compliance with the law.
