You can use a special standard meal allowance of $59 per day if you work in the transportation industry, which includes those whose work directly involves moving people or goods by bus or truck, regularly requires them to travel away from home, and, during any single trip, usually involves travel to areas eligible for different standard meal allowance rates.
You would use your log book and multiply the $59 for each day you were away from home.
