KingCounty VanPool is a way where people share the Van on a monthly basis. The Van is provided by King County and everyone that is a member in the VanPool share the monthly cost.
The periodic maintenance is paid by the County. Gas (Gasoline/Petrol) is paid from the pocket.
This facility is not limited to just corporate employees, but anyone can use. When backed by the employer, the charges are usually paid by the employer and the gasoline is reimbursible.
When the cost is borne by the employer, such as Microsoft, Amazon, the penalties (such as tickets issued by Police, Parking violations) are borne by the individuals.
