A Type 1 barricade (sometimes written Type I) is the smallest of the three MUTCD-defined barricade tiers — a single horizontal rail, 8 to 12 inches tall, 24 to 48 inches long, mounted on an A-frame, single-post, or skid base. It exists for short-duration, daytime, low-speed channelizing on residential streets, parking lots, and pedestrian work zones — not for road closures and not for nighttime highway work. This article walks through the exact MUTCD spec, where Type 1 fits in the barricade ladder, and what to buy for contractor use.

The MUTCD definition

MUTCD §6F.63 defines three barricade types by rail count and rail dimensions:

  • Type 1 — one rail, 8" to 12" tall, 24" to 48" wide. Single-row alternating orange and white stripes.
  • Type 2 — two rails, same dimensions per rail. Used for the same applications as Type 1 with greater visibility for higher-speed or longer-duration work.
  • Type 3 — three rails, 8" to 12" tall, 48" to 96" wide, on dual supports. Used for road closures and detours.

All three carry the same alternating 6" stripe pattern, retroreflective Type III or higher sheeting, and the orange-on-white color. The difference is rail count and the underlying support — which scales the practical visibility and stability.

Where Type 1 fits — and where it does not

Type 1 is the right choice when ALL of these are true:

  • Posted speed ≤ 35 mph (residential and low-speed collector)
  • Daytime work only OR supplemental warning lights overnight
  • Short duration: less than one work shift in one position
  • Channelizing or pedestrian protection — not a road closure
  • No positive impact protection required (use a barrier for that)

Use Type 2 or Type 3 instead if:

  • Posted speed exceeds 35 mph — go Type 2 minimum
  • You need road closure signage — Type 3 only, with R11-2 ROAD CLOSED panel
  • Overnight without supplemental lighting — Type 2 minimum
  • Long-duration installations (more than one shift in one location)

Construction — what to look for

A field-grade Type 1 barricade has four components:

  • Rail — rotomolded polyethylene or plywood, 8"–12" × 24"–48" face. PE rails last 5–8 seasons; plywood is cheaper but soaks water and warps.
  • Sheeting — Type III prismatic retroreflective (or higher). Orange/white 6" stripes, alternating, slanted at 45° downward toward the side traffic should pass.
  • Frame — A-frame (hinged, folds flat for transport) or single-post slip-in. A-frame is the default contractor choice; single-post is lighter but tips in wind.
  • Base — sandbag pocket, water-fill base, or integrated steel feet. Water-fill bases double as ballast and footprint expansion.

Cheap commodity Type 1 barricades skip the prismatic sheeting and use lower-grade engineer-grade reflective tape. That is a citable error on NJDOT-inspected jobs. Confirm Type III prismatic or higher when buying.

Where contractors deploy Type 1

The five most common contractor use cases:

  • Sidewalk replacement — channelize pedestrians around a wet-concrete pour. Pair with caution tape between barricades.
  • Driveway and curb work — mark off a fresh cut for 4–8 hours of cure time. Single Type 1 across the apron.
  • Parking lot striping — protect freshly-painted lines from drivers. Type 1 every 30–40 ft along the protected row.
  • Manhole and inlet work — surround the open hole. Four Type 1 units form a square. (For a long-duration open inlet, upgrade to Type 2 or a barricade tape ring.)
  • Pedestrian channelizing through a work zone — guide foot traffic past an open job site on a sidewalk replacement.

What to buy — three contractor profiles

Profile A: residential contractor (driveway, sidewalk, curb)

  • 8× Type 1, PE rail, A-frame, sandbag pocket — ~$45 each
  • Plus 4× Type 2 for shoulder work — ~$90 each
  • Total kit: ~$720

Profile B: paving and parking lot contractor

  • 12× Type 1 with water-fill base — ~$55 each
  • 6× Type 2 for collector-street work — ~$110 each
  • Total kit: ~$1,320

Profile C: municipal / utility crew

  • 6× Type 1 for sidewalk and pedestrian protection — ~$55 each
  • 10× Type 2 for general lane work — ~$110 each
  • 4× Type 3 for road closures — ~$200 each
  • Total kit: ~$2,230

Common buying mistakes

  • Using Type 1 for road closure: a Type 1 barricade across a road is not a closure — it is a channelizer. NJDOT and FHWA inspectors will cite this. Closures require Type 3 with the R11-2 ROAD CLOSED panel.
  • Skipping retroreflective sheeting tier: engineer-grade tape is not MUTCD-compliant for new work. Prismatic Type III is the floor; Type IV or V is preferred for high-speed adjacent traffic.
  • Single-post bases on windy days: a single-post Type 1 in 25+ mph wind tips. Use A-frame or weighted-base versions for any outdoor work, save the single-post for inside parking decks.
  • Mixing stripe direction: MUTCD requires stripes to slant downward toward the side traffic should pass. A row of barricades with mixed stripe directions confuses drivers and is a citable inspection finding.
