California DMV Permit Test (Class C)Safe Driving PracticesMedium
You are driving in a construction zone where workers are present. The normal posted speed limit for this section of road is 55 mph. What is the speed limit you must observe?
- A25 mph, if no specific speed limit is posted for the construction zone.
- B45 mph, as it is generally reduced in construction zones.
- CThe posted speed limit within the construction zone, which is typically reduced.
- D55 mph, unless otherwise marked.
Show answer & explanationAnswer & explanation
Correct answer: C. The posted speed limit within the construction zone, which is typically reduced.
Construction zones with workers present typically have a significantly reduced posted speed limit for safety. You must always obey the specific speed limit signs posted within the construction zone, which override the normal speed limit.
Why the other options are wrong
- A. 25 mph is a common unposted speed limit for residential or school zones, not construction zones unless specifically posted.
- B. While often reduced, the exact speed limit must be obeyed as posted, not assumed to be 45 mph.
- D. The normal speed limit is superseded by the construction zone speed limit when workers are present.
Construction Zone Speed Limits
Drivers must obey the posted speed limits within construction zones, which are typically reduced for the safety of workers and other drivers.
- Fines for violations are often doubled in construction zones.
- Reduce speed further if conditions (e.g., narrow lanes, uneven pavement) warrant it.
- Watch for workers, flaggers, and construction vehicles.
Memory trick: Orange cones mean slow down and obey the new speed tone.
