Time For School, Little Blue Truck by Alice Schertle

Little Blue Truck and his good friend Toad are excited to meet a bright yellow school bus on the road. They see all the little animals lined up in the school bus's many windows, and Blue wishes he could be a school bus too. What a fun job-but much too big for a little pickup like Blue. Or is it? When somebody misses the bus, it's up to Blue to get his friend to school on time. Beep! Beep! Vroom!
