(ABC NEWS) -- Do you drive with a dog in your lap? And, should you?

U.S. President Lyndon Johnson did it-- at least once, as seen in the photo above, in which he's shown holding a dog at the window of the driver's side on the family's Texas ranch in 1967.

But what about on Chicago's busy streets? A bill in front of the Illinois General Assembly would amend the Illinois Vehicle Code to make it a violation for people to drive while holding a pet on their lap- unless in a commercial motor vehicle or agricultural motor vehicle.

While police couldn't stop a car just because a person has a pet on his or her lap, but a $25 fine for the petty offense could be tacked on if another violation occurs.

The bill is sponsored in the Illinois House by Representatives Daniel V. Beiser and Daniel J. Burke.
