Grandpa Makis' four grandchildren become passengers in this book! They will take a ride in grandpa's car, but they will also go to school by school bus. How should we behave as passengers? What should we watch out for when boarding and alighting from vehicles? Can we help drivers avoid accidents? We will read all this in the third book of the series "I Travel Safely on the Road," a series of books authored by traffic accident expert and analyst Makis Kallitsaris. The book also includes educational and fun activities that help children reinforce the information and rules.
