New South Memphis Speed Bump and Roundabout Rules

Transportation Tennessee 4 Minutes Read ยท published February 08, 2026 Flag of Tennessee

New South Memphis, Tennessee residents often ask how local rules govern speed bumps, speed humps and roundabouts. This guide explains which municipal authorities typically control installation, maintenance and enforcement, and points to the closest official sources where the city-level ordinances and traffic engineering policies are published. For ordinance text consult the Memphis Code of Ordinances on the municipal code publisher site Memphis Code of Ordinances[1] and for local traffic-calming policy refer to the City Traffic Engineering page City of Memphis Traffic Engineering[2].

Local traffic-calming decisions are managed by traffic engineering and public-works departments.

Scope: speed bumps, humps, cushions and roundabouts

Terminology and permitted devices vary: many municipalities treat speed humps, cushions and raised tables differently from regulatory speed bumps used on private property. Roundabouts are traffic-control installations that typically require engineering review, right-of-way work and planning approval. Where New South Memphis lacks separate published bylaws, the City of Memphis ordinances and traffic-engineering standards are the closest controlling sources for public streets.[1]

How decisions are made

  • Traffic engineering evaluates speed, crashes, volume and emergency-access impacts.
  • Installation on public streets often requires a formal petition or study and a council or department approval.
  • Private property installations normally rely on local zoning or building rules and may require permits.

Penalties & Enforcement

Applicable fines, civil penalties and enforcement procedures for improperly installed or altered traffic-calming devices on public streets are set by municipal ordinance or department rule; specific fine amounts are not specified on the cited municipal pages and must be checked in the official code or through the enforcement office.[1]

  • Monetary fines: not specified on the cited page; consult the municipal code for exact amounts.[1]
  • Escalation: first, repeat and continuing offences and per-day penalties are not specified on the cited page.
  • Non-monetary sanctions: removal orders, stop-work or restoration orders and court actions are typical enforcement tools; specific procedures not specified on the cited page.

When exact penalty amounts or appeal deadlines are needed, request the ordinance section from the municipal clerk or check the official code.
