Zigzag lines in Downtown Hilo on Hawai‘i Island

Traffic Markings on County Roads

No, you're not seeing things! We really did paint those zigzag lines down the middle of the street.

And we're counting on motorists to notice these zigzag pavement markings and slow down at this busy downtown Hilo intersection.

Hawai‘i County uses innovative traffic calming devices such as zigzag and shark’s teeth pavement markings. Zigzag lines are painted on the street at busy intersections and in school zones to get motorists’ attention to slow down, making our streets and highways safer for everyone. Bold stripes like shark’s teeth are painted on blind curves and are especially effective at night due to the high reflectivity of the striping.

Markings on County roads include the center lines, crosswalks, stop, turn symbols, no passing and safety zones, and parking spaces. Pavement markings are regulated by Chapter 24, Section 24-144 of the Hawai‘i County Code.
