You can find an MACRS depreciation chart in IRS Publication
463, Travel, Entertainment, Gift, and Car Expenses. Once you determine the
basis of your vehicle, when you placed it in service, and the depreciation
method you will use, you can use the chart to find your depreciation deduction
for the year. There is a limit on the maximum depreciation deduction that can
be taken each year, depending on the year in which you placed the vehicle in
service. The referenced publication also includes a table with these
limitations.
