Don't pass another vehicle if you are within 100 feet of

According to traffic laws, it is illegal to pass another vehicle if you are within 100 feet of a bridge, tunnel or a viaduct. Also, it is illegal to pass another vehicle if you are 100 feet of or traversing any intersection or railroad grade crossing. These actions are considered illegal because your visibility in those cases is very restricted. Under restricted visibility, drivers should proceed with caution. These rules exist in order to protect drivers from dangerous situations on the road.
