At 3pmET today, Fox News and CNN began covering a high speed pursuit along busy I-75 north of Atlanta. This pursuit was unique on several fronts - a big rig was being chased, and its driver was clinging to the back, presumably having been carjacked.

Also rare, was CNN's airing of the chase live. The network has historically left the reporting of high speed pursuits to HLN, which also carried the chase live. MSNBC began taking the chase at 3:05pmET after a live interview with Sen. Joe Lieberman about Arlen Specter's jump to the democratic party.

It was about that time that CNN stopped airing the chase live. Minutes later, the presumed driver of the truck jumped to safety as the truck rolled to a stop. The suspect was pulled out of the cab surrounded by more than two-dozen officers and taken into custody.
