Capo 1st fret
 G       3 2 0 0 3 3
 Cadd9   - 3 2 0 3 3
 C       3 3 2 0 1 0
 D       - 0 0 2 3 2
 Em      0 2 2 0 0 0
G                    Cadd9
I keep tellin myself this is the right thing to do
      G                                     Cadd9
I was wastin her time, waitin on dreams that just weren't comin true
         G           Cadd9
And this old highway seems to understand
G                             Cadd9
Leadin me on to somewhere that no one knows my name
          Em                             G (or C whichever you like better)
I got the window rolled down, I got the radio up
          Em                      D
I'm doin all that I can to get my mind off us
G                    D
What I need to do is turn this car around
Em                           C
Drive as fast as I can til I see the lights of our hometown
G                        D
And run to her, take her in my arms

Em                                      C
Make her see how sorry I am, well that shouldn't be so hard
      G  D  C             G
But I drive on, and on, and on
VERSE 2 just like verse one. if you know the song it should be easy placing the chords 
the right spot.
Eighty-seven more miles gets me into Baton Rogue
There's a buddy of mine who says he might find some work that I can do
Or maybe head up north to Knoxville, Tennessee
I know my baby sister, has got a couch where I can sleep
Now the sun's goin down on my broken heart
Lord, I gotta go bak before I get too far
CHORUS AGAIN
THIS IS THE END OF THE CHORUS vvvv
      G  D   C
But I drive on
       G D  C               G
Yes I drive on, and on, and on
THEN THE SONG GOES BACK TO G TO CADD9 AND USES THESE FOR THE REST OF THE SONG
Knowin what I need to do
Girl, I'm comin home to you
Knowin what I need to do
Girl I'm comin home to you
I'm comin home to you
Knowin what I need to do...
