Illinois is about to go high tech to nab speeders on expressways and in construction zones -- and thanks to clear photographs of drivers behind the wheel -- it's a ticket you can't talk your way out of. Say "cheese" and open your wallet. Illinois police are getting ready to unleash their latest weapon to catch speeders in dangerous construction zones. It's a new photo enforcement van that snaps pictures of drivers behind the wheel, their license plates, and their speed. Here's how it works: within 50 yards of the enforcement van, a radar gun locks onto a vehicle and captures its speed. The driver sees his or her speed displayed on a board above the van -- then flash, police have what they need. Drivers don't know they've been had until they receive a $375 ticket in the mail. That's the minimum fine for a first-time offense of speeding in a construction zone. The second offense will cost you $1,000. And if you hit a worker, the penalty is up to a $10,000 fine and 14 years in prison.
