My suggestion to Domino's on their uniform redesign:

Uniforms MUST include reflective accents on the hat and shirt visible from all directions, front and rear. This will make delivery drivers more visible when in the street on deliveries, and make inside employees more visible transiting parking lots to and from the store and while making trips to the dumpster or outside coolers etc.
This can be easily accomplished by adding retro-reflective pin-striping on hats and polo shirts, and on the adjustable bands on hats and into the collars of tee shirts.
This should be a mandatory component on all future uniforms and can also be incorporated into hot bags that drivers carry.
While this will add a modest cost to the uniforms, it is likely far less expensive than the costs associated with loosing employees in otherwise avoidable accidents when near cars at night.
