The Maryland State Police (MSP) declares snow emergencies with input from MD State Highway Administration. As of 8:00am, a snow emergency was declared in Montgomery County.

“Once a snow emergency is declared, the law requires certain precautions.

They include:

  • Prohibited parking on roads and streets designated as snow emergency routes; and
  • The use of snow tires/chains (most cars now use all weather tires, so changing to “snow” tires is unnecessary);

Once an emergency is in effect, all requirements are in effect until lifted.   A Snow Emergency Plan is put into effect by county.  Certain exceptions can occur while a snow emergency plan is in effect.  A specific route(s) can be lifted and the remainders of the roads in the county still remain under the Snow Emergency Plan.   If the Statewide Operations Center is notified of an exception, we will note these routes as exceptions in our list below.  Please check back periodically for updated information.”

To monitor snow emergencies, and when they are declared/lifted across the state, you can check out MDOT’s snow emergency plans.
