Speed Signs: Flashing Speed Limit Signs

Speed Control Signs
Flashing speed limit sign

Speed control signage

Speed signage advises and reminds the driver of the legal speed limit.

Speed control signs or speed warning signs can be triggered by all vehicles or only those exceeding a pre-determined safe speed.

They should be used to supplement fixed mandatory plate signing and not as a substitute for it.

Key Benefits

  • Minimal maintenance
  • High performance LED output
  • Lightweight robust casing
  • Quick and easy installation
  • Compliance with TSRGD standards

Variations

  • Amber Corner Flashers
  • SLOW DOWN Safety Message
  • Village Gateway VAS
  • Alternating safety message
  • Multi-functional speed limit sign
  • Solar powered option
  • Radar or loop activation
  • Data recording facility
  • Remote access
  • Speed type KPH or MPH

Our vehicle activated Speed Control Sign has been designed and manufactured to mirror the regulatory maximum speed limit sign (Diag 670) described in the TSR&GD (TSRGD).

The unique manual switching facility on this LED Speed Sign allows the user to instantly change both the detection speed and speed display in one operation to suit the existing limit on the road. Therefore, depending on client requirements, the sign can display “30” when positioned on a 30mph road, then switched to “40” when repositioned on a 40mph road.

The light output of the directional LED display is controlled via the inbuilt photo cell, achieving best performance whatever the light or weather conditions.

This road safety flashing speed limit sign can also be radar activated and utilised for data collection.

Applications for our Speed Signs

The TWM Speed Signs are automatically and immediately activated by the speed or presence of a vehicle approaching a change in the speed limit, an area prone to higher-than-average collisions, or a hazard that commands improved driver caution.

Designed to mirror and support mandatory speed limit signage, the addition of manual switching differentiates this model from any other. It enables users to adjust the detection speed and display formats according to changeable speed limits or conditions.

Whether users require a flashing speed warning sign they can change at varied times of the day, use in temporary placements with different speed limits, or activate signs during heavier traffic flows or higher average speeds, these signage units are uniquely versatile. They are used within:

  • Settings with variable speed limits: Schools, other educational settings, hospitals, and areas with raised bridges or level crossings may need to adapt the speed limit multiple times per day, making adjustable road speed signs an optimal solution.
  • Urban centres: Higher density footfall and congestion can make speeding prevalent in busier and larger cities, with a core need to control speeds and warn drivers with clarity about when they are exceeding the maximum limit.
  • Rural villages and towns: Countless smaller residential areas have reduced speed limits that are easy to disregard or miss, particularly when transitioning from major A roads with national speed limits. Flashing speed signage augments driver awareness and reminds motorists that their speeds are being monitored.
  • Transport hubs: Environments like airports, train stations, docks, and ports often require advanced speed management resources, ensuring pedestrians and site users are protected from avoidable risks caused by fast-moving vehicles.
  • Road hazards: On approaches to weak bridges, sharp corners or steep inclines, a well-lit LED speed control light can ensure drivers are always aware of an upcoming feature or hazard and informed when to reduce their speed.
  • Construction and development sites: Managing vehicle speeds on busy construction sites with potentially hundreds of visitors, personnel, delivery vehicles, and heavy machinery is essential to safe site navigation and risk prevention.

While these are just some of the many uses for speed signage, we also work with diverse clients and can provide more details or comparable specifications to help you select the most suitable speed management signage for your setting.

How Does Our Speed Warning Signage Help Slow Down Traffic? 

Driver complacency and inattentiveness are responsible for many preventable incidents, where speed limits are perceived as optional, unenforced or unnecessary.

Directional Speed Control Signs incorporate LED displays controlled via an inbuilt photocell, which ensures that speed warnings and calculated speeds are clearly shown in any weather or light conditions.

Using radar-activated speed detection also ensures that messaging is accurate. Data about average speeds, vehicle numbers, or responses to warning signs can be collated to assist with ongoing management.

Introducing vehicle-activated signage has been shown to:

  • Reduce average speeds by between five and seven MPH and lower the number of drivers exceeding the speed limit by as much as 50%.
  • Have a marked impact on road safety risks and issues in areas with specific concerns, such as construction sites and school zones.

Frequently asked questions

Can flashing Speed Control signs be used instead of conventional fixed signage?

No – in line with the national regulations, displaying mandatory fixed signage advising of the maximum speed limit is essential. 

However, the limited effectiveness or lack of enforcement of speed limits often means adding a flashing, responsive and vehicle-activated Speed Control Sign can significantly improve compliance.

How can a Speed Control Sign reduce collision risks?

The simplicity of an LED Speed Control Sign should not be confused with its effectiveness! 

Drivers who are shown their speed on a bright, unmissable display, with that speed visible to all surrounding motorists and site users, are considerably more likely to adhere to maximum speeds, take notice of speed limitations, and be conscious of the speed at which they are travelling.
