Driver's License Test Prep
California Practice Construction Signs

The manual says to prepare to slow down or stop for what inside a work zone?

  1. A.
    Trucks carrying hazardous loads
  2. B.
    Any vehicle towing a trailer
  3. C.
    Highway equipment ahead Correct
The Why

The answer is "Highway equipment ahead"

The manual tells drivers to prepare to slow down or stop for highway equipment inside a work zone. The hazardous-loads pick at A pulls from the paragraph just below, where the rule governs what a truck carrying gas or explosives must do at railroad tracks, not what you do around it.

Why the others miss

The traps in the wrong answers

A. Trucks carrying hazardous loads

The manual tells drivers to slow down for highway equipment; the hazmat truck rule concerns what that truck itself must do at railroad tracks. This answer reaches for the hazmat placard rule printed just below, where the diamond-shaped sign on a truck signals gas or explosives on board.

B. Any vehicle towing a trailer

The manual singles out highway equipment inside a work zone, not passenger vehicles pulling trailers. This answer applies a general habit of keeping distance behind any heavy or towed vehicle, missing that this instruction targets the road-work machinery itself.
