When winter weather strikes, the Maryland Transit Administration does everything possible to keep our scheduled routes running as smoothly as possible. Buses follow normal routes as long as the streets are safe for travel. When road conditions deteriorate, we may have to temporarily detour from our regular route until roads/areas are treated and safe for driving.

For the latest on conditions that may affect your ride, we recommend that you visit our service alerts web page, where information is posted first when service is modified. We also invite you to sign up for eNotifications delivered directly to your phone, including those that are voice and text only. And you can download and print our Snow Guide for a handy, comprehensive reference for transiting safely in wintry weather. The Snow Guide also offers a complete list of radio stations, social media sites and guidance on staying safe and informed when winter weather strikes. 

Which bus routes are affected first?

The Maryland Transit Administration will implement route modifications in phases, including restricting service to major roads or suspending service on routes,  as weather conditions warrant.   Phase 1 routes are implemented first, followed by Phase 2 and Phase 3.  During winter weather events, riders will experience increased travel and wait times due to road.

Service alerts are issued as route modifications are implemented. Please visit our service alerts page for the most complete information regarding alternate routes and bus stops as well as other service modifications and follow us on Twitter/X.
