What Is a State Travel Advisory Map?
A state travel advisory map is an official, real-time safety tool published by government agencies. These maps are designed to inform residents and travelers about current conditions that may affect travel.
They typically cover:
- Road conditions
- Severe weather impacts
- Temporary travel cautions
- Emergency or safety updates
Travel advisories are informational, not automatic travel bans.
