Know who needs a booster before the car pulls up
Mark which riders need a car seat or booster, and Kid Hop warns when a car doesn't have one. You can also leave a carpool yourself now.
Picking up a child who needs a booster, in a car that doesn't have one, is a scramble nobody wants at 7:45 in the morning.
You can now mark a rider as needing a Car seat or a Booster seat on their profile, and set how many Car seats and Booster seats your car has under Set Seats Available. Riders who need one show a car seat icon, and a car that is short shows a line like "Needs 1 booster seat". Kid Hop only warns you: you can still add the rider, in case a parent hands over a seat at pickup.
If your family no longer rides with a carpool, open it, tap ⋮ and choose Leave Carpool. Your riders and your upcoming rides leave with you, and the other parents see which rides need a new driver.
Both are free for everyone. See the steps in How to note a car seat or booster seat.
