A positive means of enforcing your one-way traffic system

One way dragons teeth
Dragons Teeth are black and yellow the correct hazard warning colours for maximum visibility to warn oncoming drivers.

Dragon’s Teeth are surface mounted and will help create a one-way traffic flow. As a safety product they present a very strong deterrent to drivers that want to travel in the wrong direction to all but the most determined drivers! Suitable for all types of traffic including HGVs. Dragons Teeth have a profile of a speed ramp so most traffic will drive slowly and safely over the Dragon’s Teeth in the correct direction, helping police a one-way traffic system on your site.

Virtually silent operation;
the Dragon’s Teeth are powered by a pair of high tensile heavy-duty steel springs. A vehicle’s wheels will lower the non-penetrative teeth as they drive over them and then quietly rise back upright to their original height and deterrent. Our springs have been laboratory tested for millions of operations.

Designed for extra safety
, the profile of Dragon’s Teeth lowered is the same as a speed ramp. Bright yellow and black combination, the correct hazard warning colours, makes the product highly visible so that oncoming drivers can clearly see the Dragons Teeth in place and obey the one-way system.


Reflective warning signs should be used
for all installations to give drivers a clear message of the correct way to drive over the teeth. It is important that the one-way system on your site is clearly signed with fully reflective DfT traffic signs that will work in all weather conditions and of course be easily seen at night time.
