Can the driver if a small sports car get a ticket for driving UNDER a large tractor on the road?

Definately

For Inconsiderate, Careless and Downright Dangerous Driving

They would throw the book at him for being a Cad, a Bounder and Absolute Heel

Yes!  IT IS AN UNSAFE ACT!   FOOL!

If you're still alive after that feat, and a police officer observes the stunt, you'd likely be arrested for reckless driving.

driver, of any kind, can get ticketed for not obeying the laws

That "small sports car would have to be a GO CART. " They are not known for doing highway speeds...and no one is risking their Lambo under the trailer. It could scratch the paint. There goes $40,000.00 just to touch it up. There is not that much room to even walk under them when they are parked. Besides there is no TICKET DISPENSING machine under any of them. Where did you get that notion.?

ONLY ON TV......where is where the ORANGE DIAPER came from. The Loser & Chief...in the WH.

No knowledge of the REAL WORLD. Everything is Special Effects or FAKE.

Don't worry about the ticket, it's the Darwin Award that you get for removing yourself from the human genetic pool that counts

They can get more than one for doing something that stupid.

Yes, very unsafe. And there is a thing about 2 vehicles in the same space.

Not when they are dead.

That's nothing but Hollywood bullshite. There's probably three cars in the entire world that can actually fit under a semi trailer
