In the above photo I'd have dialed in a +2 exposure compensation and reshot. You can do the same thing shooting manual, but it will take longer. For a "news" shot like this I'd really ramp up the ISO, and try to capture as much ambient light as possible. Shoot without the flash if you can, or as little as possible.
Adding to the flash compensation is the wrong thing to do here. The flash is causing the reflection. If you could move the flash off camera a few feet, or bounce off something, that would have helped a great deal, but obviously is not ideal for quick shooting at an accident scene.
The camera is metering properly, but the retroreflective portions of the vests are much brighter than the subjects making the camera. The camera is averaging and overexposing the retro-r portions, underexposing everything else.
