Conduct guidelines for

United States

Rules of conduct in United States

Speed limits vary by state: generally 25 to 35 mph (approximately 40 to 55 km/h) in urban areas.

On Interstate highways, the limit is most often between 65 and 80 mph (approximately 105 to 130 km/h), depending on the state and the section.

Limits are strictly enforced, including by aerial surveillance over long distances.

Maximum blood alcohol level in almost all states: 0.08 g/dl of blood (approximately 0.8 g/l).

For drivers under 21, the limit is practically 0.00 to 0.02 g/dl depending on the state.

Wearing a seatbelt is mandatory in almost all states for the driver and passengers.

Traffic lights are often located on the far side of the intersection, and not just above the stop line.

A stopped school bus with flashing lights prohibits all overtaking, in both directions of traffic.

 Tips from easy-idp.org

"In the United States, driving is on the right side of the road.

Except for a "No turn on red" sign (and except in New York City), you may turn right on a red light after a complete stop and after yielding to pedestrians and other vehicles.

Most rental vehicles have an automatic transmission: familiarize yourself with the gear selector (P, R, N, D) before driving off.

On multi-lane highways, the principle "Keep your lane" is common: you can be overtaken on the right; always check your blind spots before changing lanes.

Distances are immense: plan for fuel, water, and breaks, especially in the American West, and in case of a stop, remain in the vehicle, hands visible on the steering wheel, until the officer's instructions."
