DRIVERS are slowing down to figure out optical illusions on the road.
A series of brain teasers have popped up on roads worldwide as safety officials hope to slow cars down.
One optical illusion, showing a girl chasing a pink ball in the street, appeared in Canada, according to .
Motorists racing down the street frequently slowed to see the optical illusion.
Drivers noted that the illusion is on a school street.
The illusion, named "Pavement Patty," was temporarily seen on the street in 2010 during the back-to-school season.
"You're probably not expecting a child to run into traffic," a black sign near the optical illusion said.
The illusion wasn't an IQ test.
Instead, lawmakers used is as a ploy to get drivers to slow down.
Pavement Patty was a three-dimensional decal employed near the West Vancouver, Canada, grade school.

The decal was applied to the road to make sure drivers slowed down in the school zone.
Jennifer Smith, then-senior program manager for The Community Against Preventable Injuries, said the installation highlighted driver speed in the school zone.
"The idea behind this installation, and all of Preventable’s work, is to get people’s attention and get them thinking about their behavior," Smith said.
"Although this installation was done in 2010, Preventable still receives questions about the decal to this day."
While the installation raised awareness of road law issues, Smith said it was removed after area drivers expressed concern about the girl decal.
"Some people expressed concern that the decal would startle or distract drivers, potentially increasing the risk of a crash," Smith added.
