Read the Fact Sheet

Veterans and other beneficiaries may be eligible to have toll charges reimbursed by the U.S. Department of Veteran’s Affairs when they use a toll road to travel for care at a Veteran’s Administration medical facility. The Beneficiary Travel Benefits program is established and administered by the Veterans Administration. View details on eligibility and the VA’s procedures for reimbursement of toll charges available from the Veterans Administration.

The VA’s Beneficiary Travel Benefits program does not require that the person eligible for toll reimbursement travel in a vehicle with a Disabled Veterans or other special license plate. However, to be reimbursed for toll charges, you must submit a form to the VA with your receipt for payment of the toll charge no later than thirty days after the date you traveled to a VA facility for medical care. Download the required VA Form 10-3542.
