When you need to control traffic through a worksite, temporary road closure, or single-lane section, portable traffic signals are one of the most reliable and cost-effective tools available. They reduce reliance on traffic control personnel, operate around the clock without fatigue, and comply fully with New Zealand’s traffic management standards.

Portable Traffic Signals for Hire and Sale – Compliant, Solar-Powered, Ready to Deploy
TSL supplies portable traffic signals for hire and sale across New Zealand. Our units are solar-powered, trailer-mounted, and maintained to current NZTA and Auckland Transport requirements – ready to deploy on your next project with minimal lead time.
Whether you’re pricing a job, planning a programme, or need equipment on short notice, this page covers everything you need to know: when portable signals are the right call, what NZ compliance requires, and whether hiring or buying makes more sense for your situation.
What Are Portable Traffic Signals?
Portable traffic signals are self-contained, trailer-mounted signal units that provide temporary two-way traffic control at worksites and road closures, without the need for a permanent signal installation or a full manual traffic control crew.
Each unit consists of:
- A signal head displaying standard red, amber, and green phases to road users
- A solar panel and battery system providing continuous power without mains connection or generator
- A wireless controller that synchronises paired units to provide coordinated alternating traffic flow
- A trailer base for rapid deployment and repositioning on any road type
Units are typically deployed in pairs (one at each end of a single-lane section) and communicate wirelessly to ensure opposing traffic is never released simultaneously. More complex multi-phase configurations are also possible for intersections or multi-approach worksites.
When to Use Portable Traffic Signals vs Manual Traffic Control
Choosing between portable signals and manual traffic control (stop/go paddle operators) depends on several factors: the duration of your works, site geometry, time of day, and your health and safety obligations.
Use portable traffic signals when:
Works are longer than a single shift
Manual stop/go control requires personnel on site for the full duration. For works running across multiple days, shifts, or around the clock, portable signals eliminate the ongoing labour cost and scheduling complexity.
The lane closure is on a straight section with good sightlines
Portable signals work best where road users can see the signal clearly from a safe stopping distance. Straight road sections with adequate approach visibility are ideal.
Night works are involved
Deploying manual traffic control crews at night increases health and safety risk significantly – controllers working in low visibility on live roads face real exposure to moving vehicles. Portable signals eliminate that risk entirely for alternating flow control.
The site is in a remote or low-traffic location
For utility maintenance, rural roading works, or locations where traffic volumes are moderate and predictable, portable signals provide compliant, cost-effective control without the cost of a permanent crew.
You need a fast, flexible setup
Portable signal trailers can be towed to site, positioned, and operational within minutes. For urgent works or emergency access management, that speed matters.
Use manual traffic control when:
The geometry is complex
At intersections, staggered junctions, or sites with multiple access points, human judgement is often needed to manage vehicle interactions that a two-phase signal system can’t accommodate.
High traffic volumes require active management
During peak-hour works on busy arterials or motorway environments, a trained traffic controller can respond dynamically to queue lengths, turning movements, and pedestrian interactions in a way that a fixed-phase signal cannot.
Site conditions change frequently
If vehicles are regularly entering and exiting the worksite in a way that affects traffic flow, a controller can adapt in real time.
The works require a Traffic Management Plan specifying personnel
Some NZTA and Auckland Transport project requirements specify the use of qualified traffic management personnel regardless of site type. Always check your TMP requirements before substituting portable signals for manual control.
NZ Compliance Requirements for Portable Traffic Signals
All temporary traffic management in New Zealand must comply with the New Zealand Traffic Control Devices Manual (TCDC), administered by NZTA. For work on Auckland Transport-managed roads, the Code of Practice for Temporary Traffic Management (CoPTTM) also applies.
Equipment standards
Portable traffic signals must meet the performance and visibility requirements set out in the TCDC. This includes minimum signal head size, luminous intensity, and phase display requirements. TSL’s hire fleet is maintained to these standards – when you hire from us, compliance is not something you need to verify independently.
Siting and visibility
Signals must be positioned to provide adequate advance warning distance and clear sightlines for approaching road users. Minimum visibility distances vary depending on the posted speed limit of the road. Your Traffic Management Plan should specify signal placement.
Traffic Management Plan (TMP)
Any use of portable traffic signals on a public road requires an approved Traffic Management Plan prepared by a suitably qualified person. The TMP specifies the type of control, equipment placement, speed limits, and advance warning signage required. TSL can refer you to qualified TMP providers if needed.
Synchronisation
Paired units must be properly synchronised to prevent conflicting signal phases. TSL’s units use wireless synchronisation and are tested before each deployment. If you are unsure whether your intended use is compliant for a specific site or road type, contact our team for guidance.
Hire is right for you if:
- Your need is project-specific or short-to-medium term
- You don’t want to carry the capital cost of purchasing
- You want equipment that’s compliant, serviced, and ready to go
- Storage and maintenance aren’t something your yard can absorb
- Your demand for portable signals varies between jobs
Purchase is right for you if:
- You run ongoing traffic management operations with consistent demand
- You have yard space, maintenance capability, and technical staff for owned equipment
- The long-term economics favour ownership over your expected hire frequency
- You want assets on your balance sheet for fleet-based contracting
Frequently Asked Questions
Do I need a Traffic Management Plan to use portable traffic signals?
Yes. Any use of temporary traffic control equipment on a public road in New Zealand — including portable signals — requires an approved Traffic Management Plan. The TMP must be prepared by a suitably qualified and experienced person (SQEP) as defined by NZTA.
How long does it take to set up portable traffic signals?
TSL’s trailer-mounted units can be positioned and operational within minutes of arriving on site. Wireless synchronisation between paired units is confirmed before traffic is introduced to the controlled section.
What happens if a unit loses power or malfunctions?
TSL’s units are solar-powered with battery backup, providing continuous operation through overnight periods and overcast conditions. In the event of a fault, the signal defaults to a flashing amber mode, which signals road users to proceed with caution. Any fault should be addressed by a qualified person promptly – contact TSL immediately if you experience equipment issues during a hire period.
Can portable signals be used on state highways?
Yes, subject to approval of the Traffic Management Plan by NZTA. Requirements on state highways may be more stringent than on local roads. Confirm with your TMP designer and NZTA before deployment.
What is the hire period minimum?
Contact our team to discuss your specific duration. We accommodate both short-term and extended hire arrangements.
Do you deliver and collect?
Yes. TSL can arrange delivery and collection of hire units. Delivery logistics and costs are confirmed at the time of enquiry based on your project location.
