Cary, North Carolina residents often ask how speed bumps and roundabouts are regulated and installed. This guide explains the Town of Cary approach to traffic calming, describes typical criteria for speed humps and roundabouts, and shows how to request, appeal, or report issues. It draws on official Cary departmental guidance and identifies which offices handle design, evaluation, and enforcement so you can follow the correct administrative steps.

Overview of traffic calming in Cary

The Town evaluates traffic calming requests to reduce speeds, improve safety, and maintain emergency access. Common measures include speed humps or tables, curb extensions, and roundabout installations. Implementation follows engineering studies, neighborhood petitions, and coordination with emergency services and utility providers. For program criteria and petition details, consult the Town of Cary traffic calming pages Town of Cary Traffic Calming[1].

Traffic calming balances neighborhood safety with emergency and maintenance needs.

Typical measures and when each is used

  • Speed humps or speed tables: used on local streets with documented speed or crash problems; routing and emergency vehicle access are evaluated.
  • Roundabouts: considered at intersections with recurring safety or operational issues and where geometry and traffic volumes make a roundabout feasible.
  • Curb extensions and islands: short-term or lower-cost traffic calming to narrow crossing distances and slow turning vehicles.

How the request and evaluation process works

Residents or neighborhood groups typically start by contacting Cary Transportation or using the Town's traffic request system. Staff perform speed and volume studies, assess collision history, and evaluate emergency response impacts. If a project proceeds, design, public notifications, and possible pilot installations follow. For contact information and the online request portal, see Cary Transportation contacts Cary Transportation[2].

Engineering studies determine whether physical traffic calming is appropriate for each street.

Penalties & Enforcement

Traffic calming installations themselves are not penalties but regulatory controls; enforcement of speed limits and traffic laws on streets with calming devices is carried out by Cary Police and by citations under state and local traffic ordinances. Specific monetary fines for violations related to traffic calming features are not consistently listed on the Town traffic pages; where exact fine amounts are required, the cited code or police pages must be consulted.
