Message on phone of delayed

I'm going to be late for our meeting. I caught a bus one hour ago, but  the driver was drunk and he fell sleep while he was driving, and he crashed the bus. I'm fine.

I'm going to take a taxi. I'm hopping to arrive in 15 minutes.

This kind of messages are sent all the time and is important know how can we express our main ideas.

If we were in  the traffic, and our meeting is near, we would warn to our work about the situation.
