PennDOT Flagger Requirements for 2025 (Updated Guide)
If you're performing utility, telecom, municipal, construction, or road work in Pennsylvania, having properly trained and certified flaggers is not optional — it's required by PennDOT and OSHA.
Below is a clear breakdown of PennDOT’s 2025 flagger requirements so your crews stay compliant and safe.
1. Certification Is Mandatory in PA
Flaggers must complete an approved PennDOT or ATSSA flagger certification program. Training must cover:
Traffic control fundamentals
Hand signal procedures
Radio communication
Emergency scenarios
Work zone safety standards
Certification typically lasts 3 years, so contractors must track expiration dates.
2. Required PPE for Flaggers
According to PennDOT Publication 213 and ANSI 107 standards, flaggers must wear:
Class 2 or Class 3 high-visibility vest
Hard hat
Safety footwear
Weather-appropriate gear
High-visibility stop/slow paddle
These are non-negotiable on any roadway open to the public.
3. Proper Work Zone Setup
Flaggers must work within a compliant work zone that includes:
Advance warning signs
Cones, drums, or channelizing devices
Tapers
Buffer spaces
All required PennDOT signage
Utility Traffic Management can handle these setups for your project.
4. When You Legally Need Flagger Control
Flaggers are required when:
Lanes narrow
Traffic alternates one direction at a time
Temporary road closures occur
Heavy equipment enters/exits the roadway
Sight distance is limited
If your crew creates a road hazard, you must post certified flaggers.
5. Protect Your Company From Liability
Using uncertified flaggers or failing to meet PennDOT standards can result in:
Expensive fines
Stop-work orders
Lawsuits after accidents
Insurance complications
Hiring a professional traffic control company protects your crew and your business.
