Yes, you can if it's job related and you didn't get get reimbursed the full amount the government stipulates per mile. I'm a system-wide teacher so I drive between 6 schools during the week. I get a travel stipend of $600/year (laughable right?). When I file my taxes, I enter the estimated miles I drive per year. Then Turbo tax asks if you were reimbursed for it and how much. I enter $600 and it figures out the rest. For "other" travel expenses, you need exact amounts and such, but it basically works the same as the mileage.
