You could always do what Wyoming does..,

As a CDL trucker when Wyoming closes i80 due to weather and you keep going, it's a felony depending on how much damage or how long you kept the road closed.

It's really dangerous not just for you who is crashing, but rescue services from the tow truck drivers to the police making sure people don't crash into them while they work.

So charge people upwards of whatever it is now (read a while ago maximum fines were $10,000 and 30 days in jail)
