Winter weather can take a toll on road signs and sign posts, which often sustain damage from snowplowing operations and vehicle accidents resulting from slippery conditions or poor visibility. Traffic signs are critical because they communicate the rules, warnings, guidance and other highway agency information that drivers need to safely and efficiently navigate roads and streets. Well maintained signs help drivers make good decisions, so it is a traffic safety imperative to repair, reinstall or replace signs and sign posts that are damaged or missing.
