I've driven it several times in the rig shown in my signature. 20 feet long, 87 inches wide. No problems, although this is not a road for the chicken-hearted. Low gears, good brakes, and careful driving are a must. The road is narrow and winding. The pavement was improved a few years ago due to this road being the only coastal access during another of Hwy 1's perennial long shutdowns. Check current conditions carefully before setting out.
