Police said the accident involved "minor injuries" to the driver, but could not immediately provide specifics.

The overturned vehicle ended up against the center barrier and forced the closure of both the westbound and eastbound HOV lanes, as well as the left lane westbound. Traffic cameras showed police, fire and medical crews at the scene. The crash backed up westbound traffic for miles and impacted eastbound traffic, too.
