Historical plates any cop problems ?

I'm sure every State/Region/Province is different and their interpretation of the law is different as well.
Texas:
Classic's are registered just like a regular car and can come and go like a regular car fee's are the same. Difference is you can get a Classic car plate or use a plate of the year of manufacture but it must be a Texas plate.

Historical is for parades and shows.Fee's are cheaper and no annual inspection is required.

I imagine if you live in a rural area with a small population where most folks know each other it ain't a big deal but if you live in a big metropolis where Officer Friendly is getting kicked in the nards during daily staff meetings about raising the ticket count to generate more county revenue then you are going to be easy pickings. A lot depends on the cops discretion, your attitude and their like or dislike of hot rods in general. Just remember and it's been a common theme, it's probable cause to pull you over.
