I would think so - it may stress the snake, but it's good intentions so i wouldn't waste another minute thinking about taking my snake in or not to a vet clinic that's at least an hour away. When my python had RI, the closest exotic pet clinic was thirty minutes away and she made the ride just fine. Of course, I put her in a sealed, dark container with various ventilation holes and just let her sit in that for the ride.
:shrugs: Then again, i'm no RI professional, i'm just going on about what I would do in the situation - and antibiotics are for the best, so i'm sure your snake could last an hour ride.
