When we went into the safely van we did some stuff just like we watched a video about what to do when a truck is near and also the blind zones of trucks when they are driving.
After that we got a book and we had to answer the missing words in the sentences. I really liked this because it taught us stuff like the blind zones and where not to drive if you are next to a truck. it also teaches you to stay out of the blind zones.
If this truck comes to your school make sure you listen to what they say because you might need to know what they say one day!
