W17-1 vs W17-2
W17-1 BUMP warns of a short 2–4 in device with 12–15 in of travel. W17-2 HUMP warns of a 10–14 ft long device. Use the sign that matches what you actually installed.

Signage & compliance
The standard warning sign for a speed bump is MUTCD W17-1 (BUMP); a speed hump uses W17-2 (HUMP), usually paired with an advisory speed plaque. Mount it 100–200 ft ahead of the device, 7 ft from pavement to the bottom of the sign in a walking area, and repeat it at every entrance to the property. We supply the bumps themselves — bolt-down rubber, $260–$660 per 12 ft lane — and tell you exactly which sign and distance your layout calls for.

| Bump sign | MUTCD W17-1 (BUMP) |
|---|---|
| Hump sign | MUTCD W17-2 (HUMP) |
| Advance placement | 100–200 ft ahead |
| Mounting height | 7 ft in walking areas |
| Bump cost per lane | $260–$660 + freight |
| Signs included? | No — bumps only |

Recommended model
Signage is only half the defense. Pairing W17-1 with a visible reflective 3 in modular bump is what actually documents a good-faith traffic-calming effort on private property.
W17-1 BUMP warns of a short 2–4 in device with 12–15 in of travel. W17-2 HUMP warns of a 10–14 ft long device. Use the sign that matches what you actually installed.
Studies of advisory signage consistently show small speed reductions; the physical device is what enforces the limit. Sign it, then install it.
Both of our profiles carry high-visibility yellow with reflective bands, so the bump is visible in headlights well before the sign is readable.
The yellow diamond BUMP sign (MUTCD W17-1) warns that a short, abrupt rise in the pavement is ahead and that you should slow to the posted advisory speed, typically 5–10 mph. HUMP (W17-2) means a longer, gentler rise at 15–20 mph.
On public streets, yes — the MUTCD governs and the city specifies the sign and advisory plaque. On private property they are not federally mandated, but posting W17-1 at each entrance is standard practice and is what insurers look for after a lot incident.
100–200 ft in advance of the device on the approach, plus one at each property entrance. Mount the bottom of the sign 7 ft above the pavement where pedestrians walk, 5 ft in rural areas.
No. We supply the speed bumps and speed humps themselves, in stock in the USA. Signs are a separate purchase from a traffic-sign supplier; we tell you which MUTCD code and placement your layout needs so you order the right one.
Bolt-down install takes two people about 30 minutes per 12 ft lane: position the modules, mark the bolt holes, hammer-drill the asphalt or concrete, and torque the anchors flush. No paving contractor and no cure time.
Yes. Every kit is in stock in the USA and ships by LTL freight to all 48 contiguous states. Pallet and container pricing is available for volume orders, and freight is quoted to your ZIP code.
