Yes. Everyone knows about those blistering 'Illinois Summers...'
It may be inconvenient, but that doesn't compare to safety. You have to be able to SEE to drive safely, and tinting the windows makes it harder to see out, period. Plenty of people break that law, and plenty of people get tickets for it.
I would recommend one of those removable windshield screens. That will do wonders to keep the inside cool for your niece and nephew, and doesn't break the law to do so.
