How often should a flagger be trained or re-certified?

Flaggers play a crucial role in ensuring safety at construction sites and traffic control zones, and regular training is essential to maintain their skills and knowledge of best practices. The correct interval for training or re-certification is every 3 years.

This timeframe is established based on the need to keep flaggers updated on safety protocols, changes in traffic laws, and new techniques that may have emerged. Regular training reduces the likelihood of accidents and ensures that flaggers can effectively manage traffic, protecting both the workers on site and the traveling public. Moreover, the three-year interval strikes a balance between providing sufficient time for practice and ensuring flaggers' knowledge remains current.

Staying informed and adequately trained is vital for the role of a flagger, making the re-certification period an important aspect of maintaining operational safety in highway construction environments.
