Amend paragraph 15 in MUTCD Section 3B.18 to read:

If used, the diagonal or longitudinal lines should form a 24-inch wide marking pattern consisting of two 8-inch wide markings separated by an 8-inch wide gap or a 24-inch wide solid marking pattern. The marking patterns should be spaced 12 to 60 inches apart but with the maximum gap between marking patterns not to exceed 2.5 times the marking pattern width. Longitudinal marking patterns should be located to avoid the wheel paths and should be oriented parallel with the wheel paths.
