It should be one fluid motion - left hand grabs belt , right hand turns key. If vehicle is moving, your belt needs to be on - that is protocol.
Sleeve,
You are sort of right and mostly wrong. The 3/40 methods used for decades trained us to do exactly what you stated, however, with telematics this is no longer the proceedure.
NOW, with telematics, you must place the diad into the holder upon entering the truck, sit, latch the belt, place foot on brake THEN start the car. You can not have the car running AT ALL while belting or looking at the diad. You cannot have the diad in your hands while the ignition is in the ON position whether or not the engine is running. NO longer can you have one hand on the belt and one hand on the key.
When doing pickups, you must stop the car, turn the car off completely, pull the brake, lock in gear and then take the diad out of the holder and close out the stop even if the business owner is standing there waving you off because he doesnt have anything to pick up. NO longer can you close ANY stops while the car is in motion or the key in the ON position.
This will slow you down as you do this proceedure. There is a warning letter waiting for you if you record while IDLING or MOVING.
The company is even asking us (while on an obsevation ride) to shut the car off at intersections during red lights. No joke. One of the dumbest things ever.
There are ERR's involved with the system relating to selt belt violations, recording while idling and starting the car. There is a 6 second information delay from the moment you turn the key until it the information hits the ECU monitoring the truck. UPS has changed the device that records twice now, and this one appears to be working a little bit better.
The information is so sensitive, on cold days, if you simply have the ignition key to ON just to get the heater going, you will be spoken to for idling even if the engine is off! Same with the fan on hot days.
Either way, its by the book no matter how much longer it takes. This is the first thing UPS finds out when they go live with telematics and everyone gets on the program. Days get extended and hours increase. By the book is by the book, and UPS found a way to extend our days without us having to contribute anything in the process other than doing what we are told.
Peace.
