Zero Traffic Fatalities Task Force.

Existing law requires the Department of Transportation to include in the California Manual on Uniform Traffic Control Devices a requirement that the department and local authorities, when setting speed limits, round speed limits to the nearest 5 miles per hour of the 85th percentile speed of traffic as determined by an engineering and traffic survey. Existing law authorizes the department or a local authority to round the speed limit down to the lower 5 miles per hour increment in instances when the speed limit should be rounded up, but prohibits that speed limit from being further reduced for any reason.
