Depends on how big a bag. Make you own. Sow strong material in a tube shape. Passenger vehicles driven slowly shouldn't destroy bags too much. It doesn't take a great deal of height to divert water unless you're in a real low spot where runoff is very concentrated.
However. How much area in front of your garage do you control (legally)? If you have 10-20' you might be able to bring in some road base and then gravel and berm up a shallow rise in front of the garage. Make a speed bump. <g> It would be permanent and it would take some adjusting to get it right. Ie. standing out there watching water happen. It would need to be compacted; the better the compaction the longer it will last. Consider how you plan to clear the drive in winter; a big truck behind a big plow can move a lot of things so some thought and care might be needed. Plan where you are diverting the runoff. Actually, review your whole site and see what makes sense overall for your water.
Water control is always a challenge, always with us. Good luck.
