Vehicle abruptly brakes and blocks another on highway 

Transcript:
738, are you available to check northbound 53? It's going to be near my arm marker 147. Ed received a call from (name withheld), advising he was traveling northbound, attempted to pass a slower SUV. They then slammed on their brakes and pulled in front of him in the passing lane. He then got back into the driving lane, and as he passed him, they started honking their horn and flashing their lights. He continued northbound, but advised that vehicle did pull over under the shoulder. If you want to just check that area to make sure there's no disabled vehicles, we haven't received any further phone calls. 1040, you said it was about a mile south of where the speed limit sign changes going over the bridge. 104, please 7.6. It was 104. It was 104.
