What do I do about costs?

If you are sharing equally in the driving, you may not need to divide out the costs. However, if one person does most of the driving, you should decide on how to split the costs with the driver. Do this in advance, and consider establishing the cost based on fuel, maintenance and parking costs. Agree when money will be collected and stick to a schedule. One simple way of doing this is to use the Smart Commute Calculator or click on the ‘Cost Sharing’ button on your Carpool Zone trip information. Remember to include the cost of parking and 407 transponder charges.
