# Trucker Route

> Live 511 alerts, road conditions, mountain pass status, and weather data for professional truckers, dispatchers, and fleet operators. Live incident feeds come from 41 state DOTs, 6 more send work zones only, and there is no feed yet for Connecticut, New Jersey or Rhode Island. State DOT incident feeds and National Weather Service alerts are read every 15 minutes. WZDx work zone, NIFC and NASA wildfire, and USGS earthquake feeds are read every 60 minutes, FEMA disaster declarations twice a day, and the FMCSA / NHTSA / FHWA statistics once a day.

Trucker Route aggregates incident, weather, and chain-control data from 41 state DOT feeds, the National Weather Service, NIFC wildfire perimeters, USGS earthquake feeds, FEMA disaster declarations, and FMCSA / NHTSA / FHWA freight statistics. The site is designed for in-cab and dispatcher use: SSR-rendered for fast loads on weak cellular signal, with structured data on every page for direct citation.
