    Length of white stripes on highway

    Strange question here ... but does anyone know the average length of the 'white stripes' on standard Interstate highways, as well as the average space in between. Is there a source for that (Green Book, etc.).

    thanks in advance...

    MUTCD (Manual on Uniform Traffic Devices).

    Your state DOT standard may override the MUTCD, you should check with their standards.

    MUTCD (section 3A.05) states: "Broken lines should consist of 3 m (10 ft) line segments and 9 m (30 ft) gaps, or dimensions in a similar ratio of line segments to gaps as appropriate for traffic speeds and need for delineation."

    10' line and 30' gap is very standard. Only different one we use around here is the "puppy track" guiding across intersections, which is 1' stripe and 3' gap IIRC.

    Every state has its own MUTCD, but they generally follow the national one unless there is a very good reason.

    Jack White is about 6'1" while Meg White is about 5'3" this makes the ave white stripe about 5'7".
