For the 2017/18 income year, the reasonable amount for travel expenses (excluding accommodation expenses, which must be substantiated with written evidence) of employee truck drivers who have received a travel allowance and who are required to sleep away from home is $55.30 per day (formerly a total of $97.40 per day for the 2016/17 year).

If an employee truck driver wants to claim more than the reasonable amount, the whole claim must be substantiated with written evidence, not just the amount in excess of the reasonable amount.
