Traffic control for volunteer litter pickup crews
Volunteer litter pickup in Texas is typically associated with the Adopt-A-Highway program. Adopt-A-Highway signs are located permanently at the ends of the section of highway that is adopted. Either a folding (hinged) worker symbol sign (CW21-3a) or a vinyl roll-up version of the same sign is placed underneath the Adopt-A-Highway sign when pickup is ongoing. More details including highway safety tips and apparel for this program can be found on the web site below.
