• 8: The commercial vehicle shall record the results of roadside safety inspections.


• FDOT Scales and Inspection - CVCE Citation and Accident Electronic Recording
• 2: The roadside check facility equipment shall provide an interface for an inspector to add comments to the inspection results.
• 3: The roadside check facility equipment shall forward results of the roadside inspections to the commercial vehicle administration center either as needed or on a periodic basis. These reports include accident reports, violation notifications, citations, and daily site activity logs.
• 4: The roadside check facility equipment shall receive driver records from the commercial vehicle administration center to support driver identification and collection of driver credentials and history information.
• 5: The roadside check facility equipment shall collect safety data from the commercial vehicle and its freight equipment to help characterize the circumstances surrounding an accident.
• 6: The roadside check facility equipment shall read the driver identification card provided by the commercial vehicle driver and support cross-check of the identification data with driver records.
• 7: The roadside check facility equipment shall notify the enforcement agency of a violation describing the statute or regulation that was violated and how it was violated.


• FDOT Scales and Inspection - CVCE Electronic Screening
• 1: The roadside electronic screening equipment shall detect the presence of commercial vehicles and freight equipment approaching a facility.
• 11: The roadside check facility equipment shall send a record of daily activities at the facility including summaries of screening events and inspections to the commercial vehicle administration center.
• 12: The roadside check facility equipment element shall alert the emergency management center about a Commercial Vehicle or Freight Equipment breach, non-permitted security sensitive hazmat detected at the roadside, route deviation, or Driver-Vehicle-Freight assignment mismatches which includes the location of the Commercial Vehicle and appropriate identities.
• 13: The roadside check facility equipment shall send an alarm to the appropriate emergency management center when it has determined there has been a container breach or tamper event on a commercial vehicle or its attached freight equipment which includes identity, type of breach, location, and time.
• 2: The roadside check facility equipment shall differentiate between different types of vehicles and determine the number of axles, gross vehicle weight, and the identification of the vehicle and its cargo.
• 9: The roadside check facility equipment shall send a pass/pull-in notification to the commercial vehicle and its driver based on the information received from the vehicle, the administration center, enforcement agencies, and the inspector. The message may be sent to the on-board equipment in the commercial vehicle or transmitted to the driver using equipment such as dynamic message signs, red-green lights, flashing signs, etc.


• FDOT Scales and Inspection - CVCE Safety and Security Inspection
• 1: The roadside check facility equipment shall receive information concerning commercial vehicles and freight equipment approaching a facility that are being pulled in for safety and security inspections.
• 10: The roadside check facility equipment shall support wireless roadside inspections that are conducted remotely, forwarding data provided by the commercial vehicle via Field-Vehicle communications to the center that performs the safety assessment.
• 2: The roadside check facility equipment shall receive the safety and security inspection and status information from the commercial vehicle administration center to include information such as safety ratings, inspection summaries, and violation summaries.
• 5: The roadside check facility equipment shall send a pass/pull-in notification to the commercial vehicle and its driver based on the information received from the vehicle, the administration center, and the inspector. The message may be sent to the on-board equipment in the commercial vehicle or transmitted to the driver using equipment such as dynamic message signs, red-green lights, flashing signs, etc.
• 6: The roadside check facility equipment shall receive driver records, accident reports, and citation records from the commercial vehicle administration center to support driver identification and access to driver credentials and history information.
• 7: The roadside check facility equipment shall read expected driver identity characteristics (e.g., PIN codes and biometric data) from the commercial vehicle equipment to support safety and security checking.
• 8: The roadside safety and security equipment shall read the driver identification card provided by the commercial vehicle driver and support cross-check of the identification data with driver records.
