I know that in the SF Bay Area these days if you use a clipper card to pay fares and the total number of fares paid to a particular transit agency amounts to the cost of a day pass for that agency the clipper card will automatically treat it as a day pass had been purchased and will not charge any more fares from you account for any additional rides on that transit agency. Is this the case with San Diego County and it’s transit agencies which uses compass cards?

It is really a good idea as we don’t know how many rides we will take and whether it’s worth it or not to buy a day pass in the first place. Just an FYI in SDd County there is a Region plus day pass that is good for all transit agencies including Coaster until the end of the day for $ 12. A good bargain given a single ride fare between Oceanside and Santa Fe costs about $ 6.
