When used on straight sections of roadway, the spacing between barrier reflectors should be adjusted to ensure a minimum of three barrier reflectors are used, with a maximum spacing of 100 ft between any two barrier reflectors on guardrail or bridge rail. When barrier reflectors are used along a curved section, Table 8-3 or 8-4 should be used to determine the appropriate barrier reflector spacing up to a maximum of 100 ft. Figure 8-15 illustrates barrier reflector spacing.
