Work zone signs: orange diamonds, double fines, and lane closures
Orange instead of yellow. Work zone signs share the diamond shape with regular warning signs but the color flips you to high alert. Most states double the fines for any traffic violation in a work zone - and the DMV permit test wants to make sure you know it.

Where you’ll see work zone signs
Anywhere road work, lane closures, or construction equipment is present. Often extends a half-mile or more before the actual work to give you time to merge or slow down.
What to do
Slow to the posted reduced limit before you reach the work area. Merge early if a lane is closing - don’t zipper merge at the last second. Watch for flaggers (workers holding STOP/SLOW paddles) who have legal authority equal to a traffic signal.
Common test traps
The ‘flagger has more authority than the signal’ question. If a work zone flagger waves you through a red light, you go. If they stop you at a green, you stop. The other common trap: cell phone use in work zones is a separate offense in many states, even if it’s normally legal hands-free elsewhere.
