2. How does a Utah court handle the fine for a driver caught speeding in a highway work zone?

Why: Utah courts are required to fine a driver caught speeding in a highway work zone at least twice the amount of the regular speeding fine.

3. How does a driver know whether a Utah "flex lane" is open for use?

Why: Utah's I-15 express lanes are free for vehicles carrying two or more people, motorcycles, and vehicles displaying a clean-fuel C decal (a one-time $10 fee); a solo driver without a C decal must buy a UDOT express pass instead.
