Very fast object traveling just above low stratus clouds.I was driving south bound on 46th street off CR 358 for approx 1/4 of a mile. A white light in the sky traveling east caught my attention as it passed over the road ahead of me at a very high rate of speed. I could not see the shape as it was just above a blanket of stratus clouds. The clouds were relatively low. It was very dark and I could easily see the bright white light illuminating through the clouds as it shot through and off into the distance. It traveled in a straight line and I was able to witness it until it was no longer visible. It took no more than a couple of seconds (approx. 2 sec.) to cross the sky until out of view. I heard no sound though I was in a vehicle. No radio on. Seemed much too fast to be a commercial plane, crop duster-type aircraft or a drone.
