6. Why Virtual Weigh Stations?
Virtual Weigh Stations can identify speed, height, and weight of each axle of a truck moving at highway speed – no need for the vehicle to stop
Stop over size/over weight loads on bypass roads
Minimize damage to roads, bridges and tunnels from grossly over weight loads
Prevent size/over weight load permit fraud
Traffic management on state, county and other road arteries
Identify unsafe trucks and their companies
Efficient use of law enforcement personnel
Quick deployment, low capital and operational costs

7. Good Truck
DRAFT

8. Bad Truck

9. Violation Schedule

10. Field Observation Notice

11. WVS Location Selection
Joint study with MSP and MDTAP
Prioritize sites based on truck volume, enforcement need, and public outreach
Road surface conditions and planned resurface schedule
Availability of power and cellular service (3G or 4G)
Minimal environmental impact
No land acquisition cost (within State right-of-way)
Safe pull-off area for inspections, citations, and Out-Of-Service (OOS)
Data importance/availability for traffic engineering and pavement engineering
