I start my first shift at Amazon as a delivery driver. I heard about the cars having to be off and hazard lights on when loading the packages in. Do hazard lights work when the car’s engine and battery is off? Or just when the engine is turned off and just the battery is on?
hazard lights are directly connected to the battery and will work no matter where you have the keys. In your pocket or in the ignition with the vehicle running or not.
Assuming you’ll be driving a full size van (Transit, promaster etc) I hope you have experience parking this kind of vehicle. I rum a fleet of these vans for deliveries, most of the damage happens when parking. Look up - identify things the top of the van might hit like awnings, gutters, overhangs on carports and garages, etc. Then remember where they are and don’t hit them.
