  • Abstract:
    To minimize the severity of run-off-road collisions of vehicles with trees, departments of transportation (DOTs)

    commonly establish clear zones for trees and other fixed objects. Caltrans’ clear zone on freeways is 30 feet

    minimum (40 feet preferred) from the edge of travel way to a fixed object. Clear zone distances on conventional

    highways vary depending on conditions such as road geometry and design speeds.
