Caltrans highway design manual guardrail

Spacing posts 6 feet 3 inches apart provides resistance to guardrail deflection on impact and lessens the tendency of the guardrail to form a pocket during impact. If there is less than 4 feet, but at least 3 feet of clearance from the face of the guardrail to a fixed object, a strengthened rail section as shown in the Standard Plans should be used.
