During declared snow emergencies, parking is prohibited on major arteries and discounted parking is available at several parking lots and garages to cars that display Boston resident parking stickers. Use the drop-down list below to identify major arteries and to find alternate parking locations. You can also watch your local papers for details or call the Storm Center at 635-3050.

Parking regulations are strictly enforced during snow emergencies. Violators are subject to fines ranging from $45 to $250 and towing.

• Don't park within 20 feet of an intersection, or further than one foot from the curb.
• During a snow emergency, don't park on streets with signs declaring "Emergency Snow Artery" or "Tow Zone- Snow Emergency".
• Disabled cars blocking the roadway must be removed as soon as possible.
• Cars parked in driveways must not extend to the sidewalk or street.
• Resident parking stickers must be visible within 24 hours after the end of a snowstorm.
• Any 'spacesavers' left in on-street parking spaces that have been shoveled out must be removed 48 hours after a snow emergency has ended.
• In very rare cases, after exceptionally severe snowstorms where snowfall exceeds two feet, the mayor may expand the parking ban to include one side of secondary roads, until crews can clear the snow. The side alternates each year, with parking allowed only on the odd side in winters beginning in odd years and the even side in winters beginning in even years. For the 2009-2010 season, parking would be allowed on the odd side. This event is rare and has not happened since 2003.

The Boston Transportation Department also offers drivers the following traveling tips:

• Take extra precaution near school bus stops where children may be waiting without parental supervision.
• Treat non-working traffic lights as stop signs and proceed cautiously at intersections.
