Dear Savitri
If the activity is concerned about the quality testing, I have no objection.
But may I suggest you to put the signage on the golf car, the wording is say this golf car(s) is running test or doing some quality test, this is to reduce the question from other employees of what you are doing.
Beside, you have to be very careful while you and the below person driving the golf car in the factory area.
You must drive only on the golf car lane and control speed not to exceed the maximum.
Thank you for your understanding
Dear Khun Karan
To prevent unnecessary argument with the insurer, you may need to read the insurance policy about the coverage, I believed this is no problem but better to read it again to make sure that we don’t miss any hidden clause
