Smoke on the highway That morning, I was driving on the highway when traffic suddenly came to a standstill. There was smoke everywhere ahead of us, and I had no idea what had happened. Cars were stuck all around me, and there was nowhere to go. I immediately checked online for updates. That’s when I found out that there had been an explosion at a nearby oil refinery. That was what caused the traffic jam, and local residents had been told to stay indoors. So far, no injuries have been reported. Useful sentences: 1.
