That rate is the 45¢/$100 state levy plus the county, school-district, and (if you live in a city) municipal levies. La Grange city + fire-district levies add to the county baseline.

How much is the annual car tax in Oldham County, KY?
About $201 a year on a $15,000 car — a combined 1.341% of the car's value. A newer or pricier vehicle owes more; the tax is value × the county rate.
Does Oldham County charge sales tax on a car?
