Car park speed bump barrier

One-Way Traffic Spikes for Car Park Entrances

Traffic spikes, also called tyre killers or one-way spike barriers, are mechanical systems that let vehicles pass a car park or site entrance in the permitted direction only. A tyre travelling the right way pushes the spikes down and rolls over; a vehicle coming the wrong way meets upright spikes that damage its tyres. The housing also works as a speed bump, and no power supply is needed.

Sizes and Models

• Ready lengths: 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5 and 10 metres.
• Surface-mount mechanical spikes: screwed onto the existing surface with no excavation.
• In-ground spike unit: 1 metre manual type, recessed into the ground.
• Spare parts: spike bodies and covers in packs of 2, 5 and 10.

Where Are They Used?

One-way traffic spikes are used at residential car parks, shopping centre and office entrances, factories, logistics yards, public buildings and anywhere entry and exit run on separate lanes.

Installation and Safety Advice

Choose a length that covers the full lane width. Put clearly visible warning signs on both approaches stating that wrong-way travel will damage tyres. Crossing slowly protects both vehicles and the system. Plan an access route for ambulances and fire engines in advance, and check bodies and covers regularly so damaged parts can be replaced.

Frequently Asked Questions

Do traffic spikes damage cars going the right way? No. The spikes fold down under the tyre, but vehicles should still cross at low speed.

What length do I need? Measure the lane you want to control and choose a length that spans it completely.

Can I buy spare parts separately? Yes. Bodies and covers are sold in separate packs, so there is no need to replace the whole system.
