Road conditions and driving environments vary by island, from urban freeways and city streets to rural, coastal, and mountain routes. Visitors should follow posted traffic controls, stay attentive to changing road conditions, and check current roadwork or traffic information before longer trips. Hawaii DOT provides state highway information, roadwork notices, and traffic resources for travelers.
Heavy rain may cause flooding, standing water, reduced visibility, landslides, and road closures, especially in low lying or steep areas. The National Weather Service advises drivers not to cross fast flowing or rising water because flooded roads can become dangerous quickly.

Separate closure pages are available for Oahu, Kauai, Maui, Hawaii Island, Lanai, and Molokai, while GoAkamai provides current traffic information for major routes on Oahu and Maui.
