The Federal Highway Administration’s 11th Edition of the Manual on Uniform Traffic Control Devices (MUTCD) took effect on , and every state must adopt it as its legal standard by . If you build, maintain, or manage work zones, the clock is ticking. Below are seven headline changes—plus practical tips and Traffic Safety Store product links—to keep your crews compliant and contracts flowing.Checklist at a Glance
- New state-level adoption deadline (2 years)
- Speed-limit setting overhaul (Section 2B.21)
- Advertising ban on Changeable Message Signs (Section 2L)
- Minimum retro-reflectivity for pavement markings (Section 3A.05)
- High-visibility crosswalk requirements (Chapter 3C)
- Drum & channelizer striping pattern upgrade (Section 6K.06)
- Accessible pedestrian-route width & barriers (Section 6K.07)
1 State Adoption Deadline
The Federal Register notice confirms that all states must formally adopt the 11th Edition by . See the Final Rule ↗ Plan your specification updates and bid language now so projects let in late 2025 don’t hit paperwork speed bumps in 2026.2 Speed-Limit Setting Overhaul (§2B.21)
The familiar “within 5 mph of the 85th percentile” benchmark is gone. Engineers must now weigh crash history, roadside context, and vulnerable-road-user exposure before posting limits. For contractors, that means variable-speed-limit trailers and radar feedback signs will see wider use.

3 Changeable Message Signs: No Ads, 5-Year Clock (§2L)
Portable CMS units must display only traffic-related information—no contractor logos, sponsorships, or “Have a nice day” quips. A five-year compliance grace period gives fleets until
to reprogram or retire non-conforming units. Inventory your boards and update message libraries now.

4 Pavement-Marking Retro-reflectivity Floor (§3A.05)
Longitudinal markings on roads ≥ 35 mph must maintain ≥ 50 mcd·m−2·lx−1 under dry conditions by
. Establish a night-time inspection program or partner with a striping subcontractor who uses high-build epoxy and glass beads designed to hit the new threshold.
See Section 3A.05 ↗
5 Crosswalks Get Their Own Chapter (Chapter 3C)
Every signalized intersection now shall have marked crosswalks, and uncontrolled crossings require an engineering study. High-visibility “continental” patterns and wider stripes are encouraged, especially on roads with ≥ 40 mph or ≥ 12 000 ADT. Contractors should budget for thermoplastic or preformed tape rated for heavy traffic.

6 Drums & Channelizers: Stripes Count (§6K.06)
Plastic drums must carry at least two orange and two white 4- to 6-inch retro-reflective stripes; any gap between stripes can’t exceed 3 in.

Order MUTCD-compliant drums ↗
7 Accessible Pedestrian Routes in Work Zones (§6K.07)
Whenever sidewalk width drops below 60 in., a 60 × 60 in. passing space is required every 200 ft. Barricade legs can’t intrude more than 4 in. between 27 – 80 in. above the walking surface. Use
ADA-friendly barricades ↗
and modular ramps to stay compliant and avoid costly change-orders.

Next Steps for Contractors and Work-Zone Managers
- Audit existing device stock now and look for items that need attention.
- Update bid specs to reference the MUTCD 11th Edition.
- Train field crews on new CMS and speed-limit rules.
- Source compliant traffic drums, CMS, and high-vis crosswalk materials from
