Rascal Flatts - Life is a Highway Lyrics Meaning

This song could be percieved as a song about Hope...that life is short and no matter what burden one must attend to "break down the garden gates and sail away," their love still survives; "I love you now like I loved you then." It could equally be heard to mean that (two lovers) could survive the long, long road of heartache just waiting for the other to turn on the light as a beacon guiding one home. The vehicle (presumably truck) could also be an indication of the light to say something like, I still love you and wait for that day when we may ride the highway of forever. A fucking cruel joke that needs to end. Whoever you are and however many, I've stayed out of your life, please stay out of mine. It's gone on long enough. You can pick on me all you like, but if you so choose to pay the same homage to those I love; who are like my own blood, you will see my claws come out and I fear it won't be a pretty sight. The End.
