Many commuters like the idea of using public transportation or ridesharing, but are afraid of being stranded during an emergency. These concerns are addressed by the Charles River Transportation Management Association's (TMA) Emergency Ride Home (ERH) program.

When you register for the ERH and use an alternative mode to get to work, you'll have a ride available in an emergency.

Who can use it?

Any pre-registered member-company employee that uses public transportation, carpools, vanpools, bikes, or walks to work at least three days per week may use the program.

When can I use it?

Use of the program is limited to those who cannot travel home by their usual alternative mode due to any of the following circumstances:

  • Personal Illness or Emergency

  • Family Illness or Emergency

  • Unscheduled/Unplanned Overtime

When does the ERH not apply?

The ERH does not apply to the following conditions:

  • Weather delays or emergencies

  • MBTA or other transit delays or disruptions

  • Construction disruption to normal commuting
