Explanation of Road Condition Terms

Note: These definitions are intended to provide information to the public regarding the status of the roads during or after winter storms. However, please remember that road conditions may change rapidly, and the status of current conditions is not always readily available. It is always important for the public to be prepared to exercise caution while driving during the winter months. Please think ahead.

Normal/Seasonal: The roadway surface is normal/dry up to and including rain. This condition could have an adverse effect on pavement friction.

Fair: This is the result of precipitation, including rain, sleet, snow, or a mixture causing roadways to become partially covered. The driver may experience periods when the roadway markings may be obscured. This could be the result of continued precipitation over a period of time. This represents an advanced deterioration of the surface. Roadway markings may become difficult to see, and the surface may be slick, snow packed, and have rutted conditions. The roadway may become difficult to navigate.

Difficult: The roadway is completely covered with precipitation. Accumulation is to the point that the roadway markings are completely obscured making it difficult to differentiate between the roadway and its surroundings. These conditions make travel very difficult. This is a hazardous environment. Some weather conditions can be severe enough that roadway treatments, such as salt or sand, will not work. Emergency vehicles and snow removal equipment may be called off of the roadway due to the conditions. In the event of an emergency, it may be impossible to get emergency vehicles to a scene. This condition could also warrant Travel Not Advised. Travel not advised must be authorized by a State Patrol Supervisor or a DOT District Engineer or higher.

CLOSED / Impassable: By driving on a road that has been designated as closed, you are entering at your own risk. Emergency vehicles and snow removal equipment will most likely not be available to help you. You are not authorized to travel on a closed roadway.

No Report: If the roadway indicates no report, that means we have not been able to get anyone to give us a report from that area.
