HRS §291C-55
Heavy commercial trucks and the left lane
This law says heavy commercial trucks (10,000 pounds or more) cannot drive in the far left lane on roads with three or more lanes in the same direction, unless they can keep up with traffic and are passing another vehicle. They may use the left lane to turn or exit. County buses and van pools are exempt.
