I was drivin’ one night down I-35
I looked in the mirror at the fog filled night
I saw a big chrome grill fillin’ up my back glass
It was a semi-truck and she was on my ass

I saw big shiny bulldog on her fiberglass snout
And I knew it was the truck they all talked about
Tearin’ up the highway at breakneck speed
Dodging every scale and every DOT

Chorus: Doin’ ninety miles an hour
with a trailer on the back,
She’s a little bit Peter; she’s a little bit Mack
Spittin’ out smoke just as black as coal,
That’s another hundred miles and a gallon of oil
She’s hell on wheels and a real road hog,
Get outta the way of the big, bad dog

She lost the driver’s side door back in 89,
Had a fiberglass hood, just sanded and primed
Thirteen gears, 4 more in the back
The frame said Peterbilt, the cab said Mack

She had a queen size sleeper with satin sheets
The driver never did pull her over to sleep
Haulin’ through rain, mud, snow and sleet
Draggin’ everything from steel to Kansas wheat

Repeat Chorus

Bridge: Drop a load in Wichita
Crushed cars to Arkansas
Hot Sauce down to Louisiana
Dead head back to Texarkana
Next load goes to San Antone
Man she just keeps chuggin’ on
Hunkered down and makin’ racket,
If you can stack it, she can drag it

Yeah, yeah

So if you ever take a trip down I-35
Look in the mirror at the fog filled night
See a big chrome grill fillin’ up the back glass
It’s the big, bad dog – better move your ass!

Chorus: Doin’ ninety miles an hour
with a flatbed on the back,
She’s a little bit Peter; she’s a little bit Mack
Spittin’ out smoke just as black as coal,
That’s another hundred miles and a gallon of oil

Doin’ ninety miles an hour with a reefer on the back,
She’s a little bit Peter; she’s a little bit Mack
Spittin’ out smoke just as black as coal,
That’s another hundred miles and a gallon of oil

She’s hell on wheels and a real road hog,
Get outta the way of the big, bad dog

Boys she’s hell on wheels and a real road hog,
Get outta the way of the big, bad dog
