Hot Rods is a 1953 Mighty Mouse cartoon.
Teenage mice get out of school and drive their hot rods around town, scaring the wits out of the local townspeople. But then three bad cats hatch a plan to kidnap (mousenap?) all these teenage terrors of the road. Two of them throw up their own road detour sign to catch mice traveling through. But of course, in the end, it's Mighty Mouse saving the day!
