I was driving my daughter to glider lessons. My car was on the runway. I had my hazard lights on and my headlights on even though it was noon and sunny. I got to an intersection of road and I stopped. I looked both ways. I did see an airplane at one end but it wasn't moving. I waited about 10 seconds. I thought he might be waiting for me but I didn't have a radio to ask so I decided to cross. THAT was wrong. I didn't know better but that isn't an excuse. I thought I was delaying him but I now know that was a terrible decision for me to make. As it turned out the aircraft started approaching. I got out of the way but I scared everyone and feel terrible. In the future I will wait for as long as it takes for the airplane to leave the runway. The airplane has the right of way always.
