Truck Route Signs | Official R14-1

Truck Route Signs provide clear, enforceable guidance for commercial drivers moving through industrial zones, municipal corridors, distribution hubs, and private properties. These signs help direct heavy trucks onto approved roadways, prevent accidental entry into restricted neighborhoods, protect residential streets, and keep traffic flowing safely around loading areas and major transport routes. Our Truck Route Signs are manufactured on heavy gauge reflective aluminum designed to withstand constant vibration, high-heat conditions, rain, snow, and chemical exposure. Panels remain visible in low light and during adverse weather, making them dependable for long term roadway use.

Each sign is produced with premium reflective sheeting that meets or exceeds MUTCD specifications for traffic control devices. Edge finishing and mounting holes are predrilled for simple installation on U channel, square, and breakaway post systems. Property managers, DOT contractors, city engineers, industrial parks, and logistics facilities rely on these signs to communicate mandatory truck pathways and maintain safe routing for both commercial vehicles and passenger traffic. Whether you need a standard Truck Route layout or a supplemental arrow sign for directional control, this collection offers ready to ship options for immediate field use. These signs deliver clarity, compliance, and durability in every installation.

Truck Route Assembly & Mounting

To ensure visibility for heavy vehicles and MUTCD compliance:

  • The Assembly: The R14-1 "TRUCK ROUTE" sign is paired with an M6 Series Arrow plaque (like the M6-1R shown) to indicate the mandatory turn.
  • Mounting Height: The bottom edge of the lowest sign (the arrow) must be at least 7 feet above the ground. This clearance is critical to ensure the sign is visible over the cabs of cars and small trucks, allowing the semi-driver behind them to see the instruction in time to react.

Federal Standards for Truck Route Signs (R14-1)

Designating a mandatory path for heavy vehicles requires specific, legally enforceable signage. Truck Route Signs are the primary regulatory device used by city engineers to funnel tractor-trailers onto arterial roads that can support their weight. Under MUTCD Section 2B.45, proper installation of Truck Route Signs is mandatory for the route to be legally binding.

The R14-1 Truck Route Sign Specification

To rank as a compliant device, a Truck Route Sign must meet strict physical criteria:

  • The Code: R14-1 is the federal designation.
  • The Legend: It must feature the words "TRUCK ROUTE" in black bold text on a white reflective background.
  • The Size: The standard size for municipal roads is 24" x 18". For high-speed highways or multi-lane arterials, the size must increase to 30" x 24" to ensure visibility at distance.

Truck Route Sign Assemblies & Arrays

A Truck Route Sign is rarely installed alone. It functions as part of a directional assembly to guide drivers through complex intersections.

  • Directional Guidance: The R14-1 Truck Route Sign must be paired with an M6 Series Auxiliary Arrow (Left, Right, or Straight). This assembly tells the driver exactly where the Designated Truck Route goes.
  • Advance Warning: An "Advance" Truck Route Sign assembly should be placed 200 feet before a major intersection to give heavy vehicles time to change lanes safely.
  • End of Route: The "End Truck Route" (R14-2) sign marks the termination of the corridor, signaling the driver they are leaving the designated heavy haul network.

Reflectivity for Commercial Navigation

Commercial logistics operate 24/7. Your Truck Route Signs must be visible in all weather conditions.

  • High Intensity Prismatic (Type IV): This is the industry standard for Truck Route Signage. It ensures the white background reflects headlights brightly, contrasting with the black text for instant readability.
  • Durability: We manufacture every Truck Route Sign on .080" 5052-H38 Aluminum. This gauge is stiff enough to withstand the wind blast from passing semis without bending or fatigue.

Frequently Asked Questions

Common questions regarding MUTCD compliance, installation standards, and material specifications for regulatory signage.
Where should Truck Route Signs be placed?

Truck Route Signs must be installed at every intersection where the designated route turns. Additionally, "Reassurance Assemblies" (a standalone Truck Route Sign) should be placed periodically along the straight sections of the route to confirm to the driver that they are still on the correct path.
What is the difference between a Green and White Truck Route sign?

White Truck Route Signs (R14-1) are Regulatory. They indicate a mandatory law that must be obeyed. Green Truck Route Signs are Guide Signs (informational). For legal enforcement of a mandatory route, you must use the White R14-1 Regulatory sign.
Do I need specific arrows for these signs?

Yes. Truck Route Signs use the standard M6 series arrows. You should order the R14-1 sign along with the specific M6-1 (Left/Right) or M6-3 (Straight) arrow plaque that matches your intersection layout.
