How do I explain this

A not uncommon sight but still worth stopping to watch is the trucker explaining to the police officer how he plans to get out of this mess. He was too high to continue under the El so he turned onto Wakeling and blocked the hospital entrance. He had nowhere to go since Wakeling is one way at the end of that little stretch and he was too long to make a turn onto Griscom. I didn’t stay to see how it was resolved.
