The United States Grand Prix is held at the Circuit of the Americas (COTA) in Austin, Texas. The Circuit of the Americas is a purpose-built racing venue designed to host various motor racing events, including the United States Formula One Grand Prix.

Austin, Texas, like many other cities in the United States, is governed by traffic laws set by state and local authorities. Here are some general traffic rules and guidelines that apply in Austin:

• Speed limits are posted on signs along roads and streets and are enforced by local law enforcement. Speed limits can vary depending on the type of road, such as highways, residential streets, and school zones.
• Texas law requires all drivers and passengers to wear seat belts while driving. Children under a certain age or height may be required to be restrained in child safety seats or booster seats.
• Drivers are required to obey traffic signals, signs and markings on the roadway. This includes stopping at red lights and stop signs, yielding to pedestrians at crosswalks and obeying lane markings.
• Drivers must give way to pedestrians at crosswalks and, if necessary, to other vehicles, for example when entering a motorway or turning left at an intersection.
• Driving under the influence of alcohol or drugs is illegal in Texas. The legal blood alcohol concentration (BAC) limit for most drivers is 0.08%, although lower limits may apply for professional drivers and those under the legal drinking age.
• Texas law prohibits the use of hand-held electronic devices, such as cell phones, while driving in school zones and for certain drivers, such as those with a learner's permit or within the first six months of obtaining a provisional licence.
• Parking rules and regulations vary depending on location, for example in city centres, residential areas and business districts. Drivers should pay attention to parking signs and restrictions to avoid violating parking rules.
• It is important for drivers to familiarise themselves with local traffic laws and regulations, as violations can result in fines, penalties, and points on a driver's record.
