Vehicle Activated Signs
Radar speed signs are designed to slow cars down, to make streets safer for everyone. The signs help to make drivers aware that they are traveling above the speed limit. Speed signs have been proven to be effective, particularly with today s highly visual, often distracted drivers. Our goal is for drivers to reduce their speed once they realize they are traveling too fast. These signs can be used as a single device or in conjunction with other speed control devices such as speed bumps or speed humps. Also known as speed display signs, driver feedback signs, and your speed signs, radar signs operate on the feedback loop theory: when people are presented with information about their performance, they tend to notice and improve.

HANKUN Vehicle Activated Speed Warning Signs – Proactive Traffic Safety Solutions
In an era of congested roads and distracted driving, Vehicle Activated Speed Warning Signs are essential for mitigating risks and enhancing driver awareness. HANKUN’s innovative Speed Warning Vehicle Activated Signs combine advanced radar technology, bright LED displays, and customizable alerts to proactively address speeding—the leading cause of preventable accidents.
Core Technology & Functionality
Our Vehicle Activated systems leverage precision K-Band radar (24.15 GHz) to detect approaching vehicles up to 1,000 ft (305m) away, instantly measuring speeds and triggering real-time feedback:
- Dynamic Speed Display
- High-power LED screens (20,000 cd/m² brightness) clearly show vehicle speed (e.g., “45MPH”) in MPH/KPH, with adjustable fonts and colors for maximum visibility, even in harsh weather (IP65-rated).
- Threshold-Based Warnings: Predefined speed limits (e.g., 30MPH in school zones) activate bold alerts like “SLOW DOWN” or flashing symbols when exceeded, prompting immediate driver response.
- Three Warning Modes for Diverse Needs
- Speed Limit Reminder (SLR): Displays the posted speed limit in a red circle with “WARNING”
- Real-Time Speed Indicator (RSI): Shows exact speed with color-coded feedback (green for safe, red for excessive).
- Behavioral Feedback (BF): Engages drivers with smiley/frowny faces (SAM model) to encourage compliant speeds in residential areas.

Technical Features for Effective Operation
| Feature | Standard | Premium (Solar Model) |

| Compliance | MUTCD, EN12966, TSRGD | Same + ISO 14001 (solar models) |
Portability & Versatility
- Easy Deployment: Lightweight designs (40–60 lbs) with trailer/mast mounting options, ideal for temporary work zones, event routes, or permanent highway installations.
- Energy Efficiency: Solar-powered models offer 72+ hours of operation on backup battery, reducing reliance on grid power and lowering carbon footprint.
- Customization: Tailor messages, fonts, and warning thresholds to match local regulations (e.g., UK’s TSRGD, US MUTCD standards).
Proven Impact on Road Safety
Independent studies show our vehicle activated warning signs deliver measurable results:
- 25% Average Speed Reduction in school zones within 2 weeks of deployment.
- 30% Fewer Speeding Incidents in residential areas, thanks to constant visual feedback.
- Data-Driven Insights: Capture metrics like 85th percentile speed, peak speeding times, and vehicle counts to inform traffic calming strategies (e.g., adding speed bumps or variable limits).
Why HANKUN Leads in VAS Innovation?
- Rugged Durability: Hot-dip galvanized steel frames and NEMA 3R enclosures withstand -34°C to +74°C temperatures and 40mph winds.
- User-Friendly Control: Three internal dials or remote Bluetooth app (TSR-Connect™) for easy threshold adjustments and system monitoring.
- End-to-End Solutions: Design, manufacturing, installation, and maintenance—all backed by a 3-year warranty (5-year for solar components).
Applications
- Urban Areas: Reduce speeding in busy streets and near crosswalks.
- Rural Routes: Alert drivers to sharp curves or livestock crossings.
- Construction Zones: Guide vehicles through temporary speed limits, protecting workers.
- School Zones: Engage young drivers with smiley-face feedback, fostering safe habits.
