The main purpose of this legislation is to improve the financial support provided to veterans for travel related to their healthcare. Specifically, it aims to increase the mileage reimbursement rate for veterans who use their personal vehicles to travel for medical appointments or treatments through the Department of Veterans Affairs (VA). Key provisions of the legislation include a requirement that the mileage reimbursement rate for veterans must be at least equal to the rate that government employees receive when they use their own vehicles for official business.
