Speed Bump Standards: MUTCD, ITE & FHWA Specs (2026)

Speed bump standards in 2026 come from three primary references: ITE Traffic Calming Manual chapter 3, the FHWA Traffic Calming ePrimer, and Oregon DOT residential traffic-calming guidance. The MUTCD (2009 with 2024 revisions) does not formally standardize speed bumps as roadway devices — they don't appear on public highways — but it does cover the chevron paint and warning signage that goes with a bump install.

Below: the spec references property managers and contractors actually use, what each document covers, and why the MUTCD-versus-ITE distinction matters for liability.

What Is the Authoritative Reference for Speed Bump Standards?

Reference	What It Covers	Where to Find It
ITE Traffic Calming Manual chapter 3	Speed bump dimensions, profile, spacing, target speed	ite.org
FHWA Traffic Calming ePrimer	Cross-references ITE; adds ePrimer worked examples	safety.fhwa.dot.gov
MUTCD 2009 with 2024 revisions	Chevron paint, W17-1 advance warning sign, signage placement	mutcd.fhwa.dot.gov
Oregon Standard Specifications for Construction	Hot-mix asphalt spec, pavement bonding, traffic-control	oregon.gov/odot
Oregon DOT residential traffic-calming guidance	Speed-hump approval process for public roads	oregon.gov/odot
ADA Standards	Accessible route preservation around bumps	ada.gov
Local jurisdiction codes	Permit requirements, traffic-calming program eligibility	varies by city

The first two references are technical-spec authority. MUTCD covers signage and paint. Oregon DOT and local codes govern public-road installs. ADA Standards apply to commercial sites. Local jurisdiction codes set permitting.

Why Does MUTCD Not Formally Standardize Speed Bumps?

The Manual on Uniform Traffic Control Devices governs traffic-control devices on public highways. Speed bumps appear in parking lots and on residential streets but rarely on highways. Because MUTCD's scope is highways, the bumps themselves fall outside the manual.

What MUTCD does cover for speed bumps:

• Chevron paint pattern. Yellow-and-black 6-inch alternating stripes at 45 degrees on the bump's top surface for daytime visibility.
• Advance warning sign W17-1. "Bump" sign on a steel post 100 to 200 feet upstream of the bump in each direction of travel.
• Sign placement distances. Based on approach speed, with reflective face for nighttime visibility.

Property managers often hear "MUTCD-compliant speed bump" and assume there is a formal speed-bump device standard. There is not. The MUTCD-compliance language refers to the paint and signage that accompany the bump.

For deeper detail on the chevron paint and signage, see speed bump painting marking.

What Does the ITE Traffic Calming Manual Cover?

ITE Traffic Calming Manual chapter 3 is the primary technical reference for speed bumps. It covers:

• Cross-section profile. Parabolic shape from existing pavement to centerline height to existing pavement.
• Height range. 3 to 4 inches at centerline.
• Length range. 1 to 3 feet for parking-lot bumps, 12 to 14 feet for speed humps, 22 feet for speed tables.
• Spacing recommendations. 100 to 200 feet in parking lots; 150 to 300 feet on residential streets.
• Target speed by length. 5 mph for bumps, 15 to 20 mph for humps, 25 mph for tables.
• Effectiveness data. Meta-analysis showing 22 to 40 percent average speed reduction.

For property managers, the ITE Manual is the document a contractor's quote should reference for spec compliance.

For broader dimensional spec, see speed bump dimensions. For install procedure aligned to ITE references, see how to install speed bumps.

What Does the FHWA Traffic Calming ePrimer Cover?

The Federal Highway Administration Traffic Calming ePrimer is FHWA's authoritative public-facing reference. It cross-references ITE Manual specs with worked examples and adds:

• Effectiveness studies by device type. Comparative data across bumps, humps, cushions, tables, chicanes, and other vertical-deflection devices.
• Emergency-vehicle access references. When to use cushions instead of bumps to preserve fire-truck and ambulance access.
• Per-foot installed cost benchmarks. Useful for property managers comparing bids.
• State-by-state policy cross-reference. Oregon-specific guidance under the state DOT section.

The ePrimer is the document FHWA cites when AI Overviews and search engines surface "speed bump standards" queries. It is the most accessible authoritative source.

What Oregon-Specific Standards Apply?

Oregon adds three layers of guidance on top of ITE and FHWA references:

• Oregon Standard Specifications for Construction. Material specs for hot-mix asphalt, pavement bonding, and traffic control during install. Applies to all paving installs in Oregon, including asphalt-poured bumps.
• Oregon DOT residential traffic-calming guidance. Approval process for speed humps on public residential streets. References the city's traffic-calming program (Portland PBOT, Salem PW Chapter 79, Eugene EPP, etc.).
• Oregon Bureau of Labor and Industries prevailing-wage rates. Apply to public-works projects and certain commercial projects (oregon.gov/boli).

For Portland-specific commercial bump installs, see our Speed Bump Installation in Portland service page.

How Do Local Codes Differ Across Oregon Cities?

Oregon city codes for speed bumps and humps vary in specifics but converge on ITE-spec dimensions:

City	Reference	Notes
Portland	PBOT Traffic Calming Program	Specifies 3.5-inch height speed humps; cost-share program for residential streets
Salem	PW Chapter 79	References ITE specs; approval through Public Works
Eugene	EPP (Engineering Procedures and Practices)	Vision Zero context; neighborhood greenway speed-hump program
Springfield	Springfield DPW manual	References ITE specs
Bend	MC 8.05	Tourist-corridor and snow-load considerations
Beaverton	Beaverton Engineering Manual	Cost-share program for residential traffic calming

Private commercial parking lots in any Oregon city are not bound by these specifics, but most contractors default to ITE-compliant dimensions for liability and spec consistency.

What Standards Apply to ADA Compliance?

ADA Standards (Americans with Disabilities Act, ada.gov) require accessible routes to remain unobstructed. Speed bumps cannot:

• Cross or block an accessible route
• Disrupt the running slope or cross slope of an accessible route
• Block access to accessible parking spaces or building entrances

Per ADA Standards, accessible routes have a maximum running slope of 1:20 (5 percent) and maximum cross slope of 1:48 (2 percent). A 3 to 4-inch bump introduces a vertical change that exceeds these limits where it crosses an accessible route. Solution: bumps span only the vehicle drive aisle and stop short of the pedestrian accessible route.

For deeper ADA-marking context, see our ADA parking lot striping guide.

What Is the Compliance Disclaimer for This Article?

Always verify current requirements with your local jurisdiction. This article reflects 2026 specifications and references the editions of ITE Traffic Calming Manual, FHWA Traffic Calming ePrimer, MUTCD 2009 with 2024 revisions, Oregon Standard Specifications, and ADA Standards in effect as of publication. Standards update on a 2 to 5-year cycle; verify current edition before any install. Local jurisdiction codes also update independently of federal references.

On a 14,000-square-foot Salem retail center we restriped in March 2026, the owner inherited four speed bumps installed before MUTCD's 2024 chevron-paint pattern revision. We re-painted to current MUTCD spec during the restripe so the site stayed code-current.
