General roadway conditions will be provided by the SHA and MDTA maintenance shops for the Interstate, Primary and Secondary state highways in each county. Only state maintained roads (roads with prefixes of I, US and MD and a route number) will be reported on CHART Web Mobile.

The conditions for a specific area will only be displayed if the information is less than 6 hours old. If an area is not listed, then there are no current conditions available at this time. The reporting maintenance shops will be listed by county.

These conditions are to be used for providing Traveler Advisories and general road conditions to motorists and may change rapidly during storms. The conditions reported may not always reflect the actual conditions on every roadway within a shop's reporting area. Motorists are urged to use these conditions as a guide along with other available information to gauge the severity of the roadways in their area. Motorists are always advised to use caution when driving in winter weather events.
