Squirrels are often seen as intelligent creatures, but this intelligence does not always protect them from becoming roadkill.One reason for this is that squirrels are not very effective at judging the speed of oncoming traffic. They also have a strong preference for crossing roads at right angles, which puts them in the path of oncoming vehicles more often than if they crossed at other angles. Additionally, squirrels are more likely to take risks when searching for food, which can lead them into busy roads.
