The NASCAR Cup Series haulers entering Bristol Motor Speedway is one of the craziest looking things you'll ever see. The 80,000 pound big rigs loaded with 2 NASCAR haulers and all sorts of equipment and tools enter at the crossover gate at the entry to turn 3 on the half mile high banked track, come down the steep banking, making a left turn to drive toward turn 2 on the backstretch.
They go all the way around the track and make the tight turn to enter the infield garage area almost directly across from where they entered the track. They could potentially come straight across into the infield but looping around the track allows all of the trucks to get into the facility quicker, clearing the last trucks from the roadways entering the speedway.
They come in in a specific order that allows them to park efficiently, at first alternating teams' trucks parking at spots on opposite ends of the garage, but putting each team side by side with its own team trucks.
It's a very organized and precise process with each truck lining up it's left tires on the white line and then the back of each truck's trailer lined up on the exact spot to put them all in a very nice straight line.
