You enter a marked Safety Corridor. What should you do?

  1. A.
    Turn on your lights for safety. Correct
  2. B.
    Reduce your speed by 10 mph.
  3. C.
    Slow down for the work zone marked by diamond-shaped flags.
  4. D.
    Turn on your hazard lights.
The Why

The answer is "Turn on your lights for safety."

Safety Corridors are designated stretches of highway with more fatal and serious injury collisions than the statewide average. The instruction when driving through one is simple: turn on your lights for safety. The signs identifying a corridor may include diamond shaped flags, but those flags are part of the corridor signing itself, not a work-zone marker. There is no fixed speed reduction tied to the corridor; the posted speed limit still governs.

Why the others miss

The traps in the wrong answers

B. Reduce your speed by 10 mph.

No fixed speed reduction applies in a Safety Corridor; the instruction is to turn on your lights. The posted speed limit still governs. Misreading: Invents a fixed mph speed reduction. The manual's Safety Corridor instruction is to turn on your lights, not to drop speed by a set amount.

C. Slow down for the work zone marked by diamond-shaped flags.

The diamond shaped flags may appear on the signs identifying the Safety Corridor itself; they do not mark a work zone. The corridor instruction is to turn on your lights. Misreading: Mistakes the diamond shaped flags that may appear on Safety Corridor signs for work-zone flagging, turning the corridor into a construction zone.

D. Turn on your hazard lights.

Turning on your lights means your vehicle's regular driving lights for visibility, not hazard flashers. Hazard lights signal a stopped or disabled vehicle and would confuse drivers behind you in moving traffic. Misreading: Misreads the manual's "Turn on your lights for safety" as a directive to activate hazard flashers rather than the vehicle's regular driving lights.
