C-9 5. When/how should this information be available to the inspections site? (select one) a) Well before the inspection station (perhaps two miles) so that a decision to inspect/not inspect can be made and a return signal sent within sufficient time to allow the truck to enter or bypass the station b) Upon entering the exit ramp for inspection, but before scales/scalehouse (about the same point where WIM equipment is often positioned) c) In front of scalehouse to allow visual inspection d) Anytime/anywhere while vehicle is on the highway, upon request from any computer terminal (including mobile) 6. What diagnostic or status information should be available to the driver? (select one) a) All diagnostic information should be available to the driver upon manual query of an inter- face screen or terminal b) Fault/No fault lights for each system (but not performance or operational values) c) Graduated warning signals for various systems with an indication of when a "violation-level" situation has been reached 7. If only a safety critical subset of information could be transmitted to the inspection site (due to limitations of the wireless communications media and the speed of the vehicle), please select the top three items that should be included in this "safety critical" message (select all that apply) __Brake Condition __Tire Condition __Suspension __Driver HOS __CDL Information __Vehicle Inspection History __Fuel System __Exhaust System __Lights __Frame __Other (please specify) _____________________________ 8. If the on board sensors report all vehicle systems are functioning properly, what other conditions/ information would be needed in order for the truck to be permitted to bypass the inspection station, even if it were randomly sample for inspection? (select one) a) None--Anytime all sensors report no fault, the truck may bypass station b) Would still need/want U.S. DOT registration number to check carrier history c) Would still need/want CDL information to check driver history d) For trucks randomly sampled for inspection, no matter what information about the carrier, driver or truck was transmitted; the truck would still need to pass in front of inspectors at slow speed to allow for quick visual inspection e) Other_____________________________ 9. What is your main concern with implementing an "automated" wireless type of safety diagnos- tic system? (select one) a) Electronic falsification of data b) Accuracy of measured data c) Operator resistance to implementation d) Added operational and maintenance requirements e) Other (please specify) _____________________________ 10. Which portions of a level 1 inspection could be eliminated if on board diagnostics were imple- mented? (select all that apply) __Driver HOS __Driver Qualifications __Tire condition __Brake Condition __Lights __Suspension __Frame __Cargo Securement __Exhaust System __Fuel System __None, visual inspection is always required 11. If a driver knows the truck they are driving is underweight, but also knows one or more items would fail inspection based on the automated on-board diagnostic system, do you feel drivers would disable the system in order to "take their chances" with random selection? a) Yes, most drivers b) Yes, but very few drivers

C-10 c) No, most drivers would be more concerned about disciplinary actions by their employer (or con- cerned about threat of severe fines by the State) if such a system were purposely tampered with. d) Other (please comment) _____________________________ 12. On the opposite side, if a `no fault' signal allows the truck to bypass the stations, how prevalent will `black boxes' that emit this signal become? (select one) a) It will be a significant problem b) Minor problem, stiff penalties would discourage the use of such devices c) Minor problem, data encryption is advanced enough to prevent it d) Cannot predict 13. Considering possible falsified signals or privacy concerns, what system would be most appro- priate to use for communications between vehicle and inspector? (select one) a) Encrypted, off the shelf WiFi b) Private cellular communications c) Private satellite communications d) Other proprietary system not available to the public 14. Regarding driver HOS violations, what would be sufficient to transmit to the inspection station? (select one) a) A simple "in-violation" versus "no-violation" signal b) Transmit coded information that shows if an operator is approaching a violation threshold c) Show actual HOS for each rule (10/15, 70 hr, etc.) d) Must show complete logbook regardless of status of violation 15. Considering tire condition monitoring, what information should be transmitted to inspectors to determine the condition of the tire? (select one) a) Pressure only for all tires b) Pressure and temperature for all tires c) Fault/no fault flag only (green/red/amber light) d) Pressure or temperature, only for the tires flagged as faulty 16. Regarding tire pressures, what is the threshold for which you would like to see the tire pressure flagged as a problem? (select one) a) 30 psi b) 60 psi c) 70 psi d) 80 psi e) 90 psi 17. What should the threshold be if two or more tires are underinflated? (select one) a) 30 psi b) 60 psi c) 70 psi d) 80 psi e) 90 psi f) Other (please comment) _____________________________ 18. Considering brake condition monitoring, rank the following items in importance to determine the overall condition of the brakes (1 being most important) __Air Leaks __Brake Stroke __Thickness of lining __ABS functionality 19. Regarding the condition of the brakes, please select what single piece of information should be transmitted wirelessly to the inspector __ABS status __Brake stroke in/out of spec __Brake lining thickness __Air leak rate __Overall fault/no fault
