This may be the most literal form of 'concrete evidence' I've ever seen.

A Minnesota motorist is facing a pretty big insurance claim after doing approximately $100,000 in damage on Highway 63 in Olmsted County. Minnesota road crews were pouring fresh concrete and somehow a motorist got around a construction barricade and traveled around 1,000 feet.

This is why work zones are blocked by barricades, signs, cones, etc. Don’t make this costly mistake, never go around construction signs or move cones to enter a work zone

The motorist was ticketed and the state filed an insurance claim with the driver to cover the damaged roadway due to the tracks that were created in the fresh concrete.

I can only imagine the damage that was done to the driver's car.
