This guide summarizes key traffic bylaws and enforcement for Manchester, New Hampshire, focusing on speed limits, right-of-way rules, traffic-calming measures and how DUI enforcement is handled locally. It explains which city code pages and departments enforce rules, how to report concerns, and practical steps for residents and drivers to comply with municipal requirements.

Speed limits

Speed limits on city streets in Manchester are established by ordinance and by posted signs; local speed regulations and sections of the city code are published in the Manchester Code of Ordinances.[1] For specific posted limits consult signs on site and the city traffic department before requesting changes.

  • Know posted limits: follow pavement signs and signals.
  • School zones and special speed reductions are posted and enforced during specified hours.
  • To request a change to a posted speed limit, submit a written request to the Traffic Division; see Help and Support for links.
Always treat posted signs as authoritative until an ordinance or sign is changed.

Right of way

Right-of-way rules on Manchester streets generally follow the traffic control devices and state right-of-way law as applied by local enforcement. When municipal ordinances specify intersections or special rules, those are posted in the city code and administered by the Traffic Division and Police Department.[1]

  • Yield to pedestrians in crosswalks where marked.
  • Obey traffic-control devices; failure to yield to posted signs is a violation enforceable by the Police.
  • Report hazardous intersections to the Traffic Division for review.

Traffic calming measures

Manchester implements traffic-calming tools such as speed humps, curb extensions, signage changes and temporary curb markings after engineering review. Requests are assessed by the city Traffic Division or Public Works and may require traffic studies; exact procedures are described on the department pages linked below.[2]

  • Traffic studies: the city may require counts or speed studies before installing calming measures.
  • Petitions: neighborhood requests should include specifics and evidence of traffic concerns.
  • Installation and maintenance are scheduled by Public Works following approval.

Penalties & Enforcement

The City of Manchester enforces traffic ordinances through the Police Department and Traffic Division; where violations intersect with state law (for example, DUI/OUI) state statute and state enforcement also apply. The Manchester Code of Ordinances and the Police Traffic Unit describe enforcement responsibilities.[1][2]

  • Monetary fines: specific fine amounts for municipal traffic ordinance violations are not specified on the cited municipal code pages.
  • Escalation: first, repeat, or continuing offences and any graduated fine schedule are not specified on the cited municipal code pages.
  • Non-monetary sanctions: enforcement can include warnings, issuance of tickets, orders to correct violations, and referral for court action; seizure or license actions are handled under state law where applicable.
  • Enforcer and complaints: Manchester Police Traffic Unit handles on-street enforcement and complaint intake; see Help and Support for contact and online complaint forms.[2]
  • Appeals and review: procedures to contest tickets or orders generally proceed through the municipal or state court system; specific time limits are not specified on the cited municipal pages.
If a penalty or timeframe is not stated in the municipal text, consult the issuing officer or court for precise deadlines.

Applications & Forms

The city posts forms and submission instructions for traffic requests, petitions for traffic calming, and parking or sign requests on department pages. If no form is required, the department accepts written requests; specific form names or numbers are not consistently listed on the main ordinance page.[2]
