Wheel Stops
Wheel Stops for Fleet Yards and Truck Parking: Heavy-Duty Spec

Fleet yards need 8x6x84 inch heavy-duty reinforced concrete or premium rubber wheel stops, anchored with 1/2 inch by 24 inch hardened steel spikes (asphalt) or 5/8 inch by 10 inch rebar pins (concrete). Paint is OSHA 1910.144 yellow with diagonal black stripes for combined caution and physical-hazard zones. The fleet-yard spec matches the warehouse-spec because impact loads and strike frequency are similar; the main difference is anchor depth, which goes deeper in fleet yards because of overnight settling and lateral truck movement.
Three factors drive the heavy-duty spec:
For warehouse-spec context see wheel stops for warehouse loading docks. For trailer and semi specifics see wheel stops for trailer and semi parking.
Fleet-yard anchor depth varies by substrate:
| Substrate | Anchor Type | Depth |
|---|---|---|
| Asphalt, 4 inch section | Steel spike, 1/2 by 18 inch | 18 inches into asphalt + base |
| Asphalt, 6 inch section | Steel spike, 1/2 by 24 inch | 24 inches into asphalt + base |
| Asphalt, 8 inch section | Steel spike, 5/8 by 24 inch | 24 inches into asphalt + base |
| Concrete, 6 inch slab | Rebar pin, 5/8 by 8 inch | 6 inches into concrete |
| Concrete, 8 inch slab | Rebar pin, 5/8 by 10 inch | 8 inches into concrete |
| Concrete reinforced fleet pad | Rebar pin, 5/8 by 12 inch | 10 inches into concrete |
The U.S. Federal Highway Administration's pavement maintenance guidance covers asphalt-section thickness specifications for heavy-truck loading; verify the substrate thickness before specifying spike length.
Layout considerations specific to fleet yards:
One wheel stop per stall, 8x6x84 inch, set 36 to 48 inches from the curb (deeper setback than retail because truck overhang is greater). For semi tractors with 78 to 96 inch axle tracks, the 84-inch length catches both axles squarely.
Forklifts in fleet-yard staging areas need 8 to 12 foot turning radii depending on capacity. Wheel stops within those radii get hit by forklift forks, mast bottoms, and tire shoulders. Layout-mark the forklift turning circles before installing wheel stops; keep stops outside the marked zones.
Fire codes in most Oregon jurisdictions prohibit wheel stops in active fire-lane stalls. Verify with your local fire marshal before installing in any stall that abuts or transitions a fire lane. Cojo customers in Portland and Hillsboro have lost stops to fire-marshal flag-and-remove inspections; better to verify up front.
OSHA 1910.176(c) walking-working-surface requirements apply to fleet-yard pedestrian routes. Where employees walk between truck-staging stalls and the breakroom or shipping office, install wheel stops at all stalls along the route. The painted yellow body and ASTM Type III reflective tape provide the visibility OSHA inspectors look for.
For OSHA detail see wheel stop OSHA requirements.
OSHA 1910.144 sets the safety color code for fleet-yard wheel stops:
Reflective tape on the front face is mandatory for night and pre-dawn visibility — fleet yards run early-morning shifts when natural lighting is poor. ASTM Type III high-intensity tape, 1 inch by 8 foot full length, is the fleet-spec standard. For application and cure detail see how to paint wheel stops.
Fleet yards refresh wheel stops faster than warehouses or retail because the impact loads are concentrated and recurring:
| Year | Action |
|---|---|
| Year 0 | Initial install |
| Year 1 | Quarterly inspections, paint refresh on damaged stops |
| Year 2 | Repaint pass on all stops, replace reflective tape |
| Year 3 | Anchor pull-out test on a 10 percent sample |
| Year 4 to 6 | Body replacement on stops with through-cracks or anchor pull-outs |
| Year 7 to 10 | Full lot refresh (most stops replaced) |
A Portland fleet customer (regional logistics carrier) we serviced in February 2026 had a 38-stall fleet yard with:
The yard had been running a previous-tenant retail-spec wheel stop install (4x6x72 rubber, asphalt-spike anchored). Within 14 months, 19 of the 36 stops with installations had cracked, anchor-pulled, or shifted out of layout.
We pulled the failed stops, patched anchor holes, and replaced with:
The forklift staging zones got bollards and painted hatch-marks instead of wheel stops; bollards are the right tool for forklift-route protection.
Total project was 3 days for a four-person crew. Projected replacement cycle on the new stops is 5 to 7 years, vs the 14 months the previous retail-spec stops survived. Annual amortized cost dropped roughly 65 percent.

| Item | Range |
|---|---|
| 8x6x84 reinforced concrete wheel stop, supplied | $95 to $180 |
| Heavy-duty rubber 8x6x84 wheel stop, supplied | $140 to $260 |
| 1/2 by 24 inch hardened steel spike, each | $9 to $22 |
| Polyurethane construction adhesive, per stop | $14 to $32 |
| ASTM Type III reflective tape, 1-inch by 50-foot roll | $25 to $65 |
| Per-stop installation, asphalt anchor with adhesive | $55 to $115 |
| Per-stop installation, concrete substrate | $65 to $145 |
| OSHA 1910.144 paint with diagonal stripes, per stop | $22 to $48 |
| Mobilization fee for fleet-yard install | $250 to $750 |
Heavy-duty fleet-yard wheel stops are running roughly 14 percent above 2024 baseline. Lead times on 8x6x84 reinforced concrete stops have stretched from 2 to 4 weeks ex-stock to 6 to 10 weeks for some Oregon distributors. Plan installs at least 8 weeks ahead of need, particularly for fleet-yard openings or carrier expansions on a fixed timeline.
Fleet operators spec'ing a new yard or refreshing an existing one should start with the wheel stops buyer's guide for product context and contact Cojo for a fleet-specific quote.
