Its very rare for me to see an operator actually carry out a pre shift check before using a forklift.

One customer I looked after in the past would send managers out in to the warehouse & stop random operators, ask to look at the pre shift check card & then the manager would check over / test the truck.

If something was found faulty by the manager that the operator had ticked ok to the operator then had some explaining to do as to why the truck hadn't been defected.
