Flags and signs are required on vehicles over 8’6″ wide, over 80′ long, or with over 10′ of overhang. Signs are also required when overweight only. For night running, amber marker lights are required at the front corners of the load and one on the left outside extreme edge, visible from front and sides, and red at the rear corners, visible from rear and sides. Los Angeles County also requires amber lights at all protrusions and at 5-foot intervals completely around the load (and red in the rear), but not over 5 feet above ground level. At night, when a rear overhang is 4 ft. or greater, it requires at least two lights or a rear light bar. A rear light bar is not needed on a long load in daylight unless turn signals and brake lights are hidden by a load.

Trailers exceeding 48 feet in length are illegal in California unless the kingpin is at the center of the rear axle. In which case, it may not exceed 40 feet. Longer trailers can be permitted only when justified by the length of the load.
