And for construction or work zones, when entering a highway construction area, Illinois law requires motorists to:

• Slow down
• Discontinue wireless use
• Yield or change lanes away from any authorized vehicles or workers in the area.

Scott’s Law or the “Move Over” law applies to all vehicles displaying flashing warning lights. Motorists are required to move over when encountering any stopped/disabled vehicles, when it is safe to do so.

Violators could face a maximum fine of up to $10,000.
