According to publication 463 over the road truckers can claim $63 a day and instead of the 50% it is 80%. The publication reads as follows: Special rate for transportation workers. You can use a special standard meal allowance if you work in the transportation industry. You are in the transportation industry if your work:
•Directly involves moving people or goods by airplane, barge, bus, ship, train, or truck, and
•Regularly requires you to travel away from home and, during any single trip, usually involves travel to areas eligible for different standard meal allowance rates.
If this applies, you can claim a standard meal allowance of $63 a day ($68 for travel outside the continental United States) for travel in 2016.
Using the special rate for transportation workers eliminates the need for you to determine the standard meal allowance for every area where you stop for sleep or rest. If you choose to use the special rate for any trip, you must use the special rate (and not use the regular standard meal allowance rates) for all trips you take that year.
