I am a company truck driver and can I deduct my meal per diem per day of $66.00

What do you mean by"company truck driver?"   If you are a W-2 employee you cannot deduct job-related expenses on a federal return since the tax laws changed for 2018 and beyond.   Your state laws might be different.

The IRS allows self-employed drivers and owner-operators to deduct certain costs under the category of “travel expenses.”

These include a per diem for meals, plus accommodations, tolls, and parking.

If you are an employee driver, you are not eligible for per diem deduction as they are job-related expenses. Under the Tax Cuts and Jobs Act, the itemized deductions for job-related expenses subject to the 2% of AGI floor are suspended for expenses incurred after December 31, 2017 through 2025.
