What Is A Traffic Spike System?
Traffic spike systems are a method of access control used worldwide to help restrict vehicular access to certain areas of facilities or properties. Traffic spike systems are built to allow vehicles to pass in one direction safely while preventing any traffic from accessing the area in the opposite direction, providing an incredibly effective and low-cost access control method. One way manual traffic spikes are designed so that when a vehicle passes over the spike strip in the correct direction, the tires safely roll over the smooth side of the spikes. In contrast, if a vehicle passes over the unit in a restricted direction, the teeth puncture the tire and immobilize the vehicle.
Applications and Common Settings
Traffic spikes are most often used to enforce one-way flow and reduce wrong-way driving in controlled lanes, especially in areas where reliable directional control improves safety and security. Common placements include parking lots, gated entrances, facility drive lanes, and other sites where drivers must enter from one direction only. These systems are also used in higher-security environments that require controlled access and consistent lane compliance.
What is the Different between Manual and Motorized Traffic Spikes
- Manual Traffic Spikes: Retracts when a vehicle passes in the correct direction (typically using spring or weight retraction). They're commonly used in locations where you want one-way control without needing authorization for every vehicle movement
- Motorized Traffic Spikes: Retracts when access is authorized (for example, when a control system approves entry/exit). These are often used where security is higher and the site needs controlled actuation.
- Surface-Mounted Spikes: Install on top of asphalt/concrete (often using epoxy + anchors) and can also function like a speed bump to help slow vehicles
- Flush-Mounted (In-Ground) Spikes: Install into a trench so the system sits level with the roadway surface, creating a lower-profile solution that is often preferred for permanent installations
Traffic spikes can be manual or motorized, and the right choice depends on how the lane is supervised and how access is granted.
Surface-Mount vs. In-Ground (Flush Mount): What's the Difference?
Mounting style affects installation time, lane profile, and how permanent the setup is.

Traffic Spike System Do's & Don'ts
- Clearly Warn Drivers and Pedestrians: Reflective/lighted signage and additional markings and illumination can improve safety and reduce liability.
- Install in a Highly Visible Area: Avoid blind spots, corners, and surprise placement where drivers can't react safely
- Consult Experienced Professionals: For system layout and spacing across the lane. Improper spacing can cause problems
- Slow Vehicles to 5 MPH Before Crossing: Use speed bumps when needed, excessive speed can increase wear and raise risk
- Choose a System Appropriate for the Environment: Especially where distracted or distressed drivers may be present
- Provide Proper Drainage Beneath In-Ground Systems: This prevent water buildup and performance issues
- Ensure Vehicles Cross at a Strict 90° Angle: Both front and rear tires need to pass perpendicular to the teeth to avoid damage and premature wear
- Install on a Curve: Vehicles must have enough straight approach and exit distance to cross perpendicular
- Install on Uneven Surfaces: Surface mounts require level pavement and in-ground requires a level bed
- Install on Brick, Gravel, Dirt, or Unstable Surfaces: Traffic spikes should be installed on concrete or asphalt (or a proper concrete pad)
- Place Spikes Where Debris & Gravel Will Constantly Enter the System: Consider a concrete pad to reduce contamination
- Skip Maintenance: Remove debris and inspect periodically to keep the system functioning properly
