That pertains to the required weight fee paid on the registration renewal.AI states:
“In New York, a non-commercial vehicle, such as a pickup truck, can be registered as a passenger vehicle if its unladen weight is 6,000 pounds or less and it is used exclusively for non-commercial purposes. If the unladen weight exceeds 6,000 pounds, it must be registered as a commercial vehicle.“
The Rivian and many other non-commercial SUVs exceed this weight.
