Drivers are required to use 4-wheel drive vehicles above the VIS because the road to the summit is unpaved, rough, and quite steep. Those traveling to the summit should always use 4WD Low Range to reduce brake failure and overheating. It is recommended to have at least 1/2 a tank of gas before proceeding to the summit. Make sure your vehicle and any items taken to Maunakea are clean to prevent the spread of invasive species.
