Kids have trouble judging traffic speed, gaps in traffic, or whether a car is coming, going or standing still.

Kids have trouble understanding that a car can't stop as quickly as they can.

Kids often think that if they can see a car, then the driver can see them, even if they are standing behind a shrub or parked car.

Kids don't realize that drivers are paying attention to many things and aren't focused on just them.

Kids are short, so being able to see in and around cars is more difficult for them.

Kids have limited ability to detect traffic in their side vision.

Kids focus on one thing at a time. When they're concentrating on a ball game in their yard, they're not thinking about nearby traffic.
