What should you do when a lower work-zone speed is posted?
Correct answer: Obey the posted limit and slow more if needed
Why
The posted work-zone limit is a maximum. Reduce speed further for workers, narrow lanes, poor visibility or other hazards. Follow the temporary lane controls and leave more space. An enhanced penalty can apply where the required work-zone notices are posted.
