0.08%. Drivers 21 and older are considered legally impaired at a blood alcohol content of 0.08% or higher in Hawaii.

What should I do at a four-way stop in Hawaii?

If you arrive before other vehicles, proceed when safe. If two or more vehicles arrive at the same time, the vehicle on the right has the right-of-way. If facing each other going straight, both may proceed; a turning vehicle must yield.

When are U-turns legal in Hawaii?

A U-turn is legal only when it can be completed safely without interfering with other traffic, is not prohibited by a sign, and you have sufficient visibility in both directions. U-turns are generally prohibited in intersections with traffic signals.
