Frequently asked questions about North America Traffic equipment

You can use these questions and answers to help you troubleshoot your traffic control equipment. If you need immediate assistance, please contact our 24-hour technical support line.


Q: Will the signals function in extreme weather?

A: North America Traffic models are engineered to withstand the most extreme weather conditions such as wind, snow, rain and heat, making them ideal for use during natural disasters.All electrical components are rated to operate at -40 C to +80 C temperatures, and our equipment has been tested and approved to meet MUTCD wind load requirements.

Q: What if I need traffic control in a remote location?

A: North America Traffic signals include solar-charged battery power for self-sufficient, 365-day operation. Even in low-light conditions, they can operate for up to 30 days without a charge. For areas that lack cellular coverage, we have optional satellite GPS devices that will tell you how the equipment is operating.


Q: How long will the traffic signals continually operate when starting with a fully charged bank of batteries?

A: Model PTL2.4x will operate 24 days with a 12-battery configuration and 30 days with a 16-battery configuration.

  • Model PTL2.4LD will operate 7 days.
  • Model RCF3.4 will operate 21 days.
  • Model RCF2.4 will operate 5 days.

Q: Can I use a generator to charge the battery bank?

A: Yes. Instructions for connection to, and the use of, a generator for charging purposes can be found in the model’s User Field Guide and Operating Manual.

Q: When should I charge my batteries?

A: Monitor the battery voltage on a daily basis when the traffic signals are in use. The voltage of the battery bank can be viewed on the signal controller display screen at any time. North America Traffic recommends charging the battery bank when the voltage reads 12.0 volts or less. Routine charging will aid in extending the life of the batteries and prevent damage due to over-discharge. Refer to the model’s User Field Guide or Operator’s Manual for detailed battery charging instructions and safe practices.

Q: How long should I leave the battery bank to charge?

A: To ensure a full charge, connect the battery bank to a charging source for a continuous 24- to 48-hour period.

Q: Will the solar panels provide a continual charge to the battery bank?

A: The solar panels provide some charge to the battery bank. You cannot rely on the solar array to provide a consistent charge to the batteries due to uncontrollable circumstances such as cloudy days, shade caused by trees and buildings, or low light conditions experienced in the fall and winter. Supplemental charging from a 110-volt AC source may be required, depending on the duration of use.

Q: Will the solar panels collect sunlight when lying flat?

A: Yes, the solar array can collect sunlight when lying flat, but it is good practice to have some tilt to the solar array. Always tilt the panels with a southern indication. This angle will increase solar absorption and assist in keeping the panels free of dirt and snow buildup. Some of North America Traffic’s traffic signal trailers are designed with a pivoting and rotating solar array to maximize sun exposure through all seasons.

Q: Is it possible to over-charge batteries?

A: All of North America Traffic’s traffic signal models use a smart charger, designed to prevent overcharging of the battery bank. Overcharging of batteries typically occurs with the use of trickle chargers (non-smart chargers) or when a battery bank is left to charge for an extended period of time (weeks or months) in very hot temperatures.

Operating traffic signals

Q: Do North America Traffic traffic signal controllers have permanent primary and secondary designations?

A: No. North America Traffic’s traffic signal controllers allow the user to assign the operating designation to any controller in use on the jobsite during initial setup. This user-friendly feature allows for quick and easy setup onsite, saving time by significantly simplifying the setup process.

Q: Do North America Traffic’s traffic signal controllers require the use of auxiliary equipment or interfaces (i.e. a laptop or micro-terminal) for the purpose of inputting signal timing parameters into the controller?

A: No. North America Traffic’s traffic signal controller hardware allows the user to quickly and easily input all the necessary settings directly, without the need for any auxiliary equipment or additional interfaces.

Q: How do North America Traffic’s traffic signal trailers communicate with each other when in use on a jobsite?

A: The most commonly used method of communication is radio communication. North America Traffic’s signal trailers can also be hardwired together for communication purposes, if required.

Q: How far apart can the traffic signals wirelessly communicate with each other?

A: Models PTL2.4x and PTL2.4LD will communicate up to one mile (1.6 km) with a clear line of sight between the signal trailers. Models RCF 3.4 and RCF 2.4 will communicate up to a half mile (0.8 km) with clear line of sight between the signal trailers.

Q: How many signal trailers can be operated in conjunction on the same jobsite?

A: Up to eight of North America Traffic’s traffic signal trailers can operate together to accommodate complex traffic control plans.

Q: Can I operate North America Traffic’s traffic signals manually?

A: Yes. All of North America Traffic’s signal trailer models can be operated manually at any time during operation by means of a radio remote control or directly from the traffic signal controller.

Q: Can I make changes to the signal timing during operation of the traffic-control equipment?

A: Yes. Changes to timing can be made at any time during operation. The altered timing will take effect the next time that phase of traffic is served.

Q: Can North America Traffic’s traffic signals detect approaching vehicles?

A: Yes. North America Traffic employs various forms of accepted vehicle detection hardware that is used to maximize vehicular flow and increase the safety of the workers within the jobsite. North America Traffic’s traffic signals can also be equipped with hardware that detects the approach of emergency vehicles and even trains. Please contact our sales department at 1-877-352-4626 or by email at for further information.

Q: Can I monitor the traffic signals remotely during operation?

A: Yes, the traffic signals can be monitored remotely with automatic notifications sent via text message or email. Please contact the office at for further information.

Q: Can I tow two of North America Traffic’s traffic signal trailers in tandem?

A: Yes, North America Traffic’s traffic signal trailers can be towed in tandem. Please refer to the local road authority’s rules and regulations.
