All drivers – new drivers especially – should be aware that stop signs can “hide” behind trucks as well as overgrown bushes/shrubs. Keep your eyes constantly moving when driving and look for clues that there’s an intersection. If you’re not sure if you have a stop sign or not, it is better to be safe than sorry; go slow enough to check it out. If you can see the back of another stop sign, then there is a 99% chance that you will be facing a stop sign too. Pay attention to the shapes of signs. Signs of this shape will never say anything else other than “STOP.” It is illegal for vehicles to park where they are obstructing the view of a sign, but it seems to happen anyway.
What else could be hiding behind the truck?
