Frequently asked questions

Are work zone fines really doubled?

In most US states, yes. Some states double fines automatically in posted work zones; others double them only when workers are physically present. Either way, expect significantly higher penalties.

What is "Slow Down or Pay Up"?

A common public-awareness campaign for work zone safety. Many states use this slogan on signs and in PSAs.

Can I be charged with a felony for hitting a worker?

Yes. Many states have enhanced penalties (up to felony charges) for injuring a highway worker through reckless driving.
