Narrative:

We were on a late afternoon sightseeing flight when the engine sputtered and then suddenly quit. I pulled carb heat. [I] looked at the fuel gauge to verify that we had plenty of fuel. [I] tried to restart the plane to no avail. Contacted tower and announced that I had an incident and was going to land on the highway. I scanned the highway for the best place to set it down and safely landed. The airplane was not damaged and no one was injured. We met the FAA two days later and they examined the aircraft. They acknowledged that the fuel gauge showed plenty of fuel on board but after further examination it had run out of fuel. The fuel gauge had failed and I had relied too much on it. I usually am careful to time out my fuel and scan the gauges. To prevent this from happening in the future I am replacing the gauge. Also; I'll always top off the aircraft before flying; visually check it and rely on my watch to accurately manage fuel use.
