Title 49 › Subtitle SUBTITLE VI— - MOTOR VEHICLE AND DRIVER PROGRAMS › Part PART B— - COMMERCIAL › Chapter CHAPTER 311— - COMMERCIAL MOTOR VEHICLE SAFETY › Subchapter SUBCHAPTER III— - SAFETY REGULATION › § 31137
Within 1 year after the Commercial Motor Vehicle Safety Enhancement Act of 2012 became law, the Secretary of Transportation must write rules that require commercial trucks used in interstate travel and drivers who follow the hours-of-service rules to use electronic logging devices. The device must accurately record a driver’s hours, record the vehicle’s location, resist tampering, and either sync with the engine or detect when the vehicle is being driven. Law enforcement must be able to read the data during a roadside check. The rules must set common screens and secure methods for driver ID, data access, data transfer between vehicles and carriers, and secure data transfer for officers. Devices must be certified under a Secretary-approved process, and uncertified devices cannot be used as proof of hours. The rules generally take effect 2 years after the final rule is published. Carriers doing driveaway-towaway operations may use either paper logs or an electronic device. An electronic logging device is an electronic tool that automatically and accurately records a driver’s hours and duty status and meets the Secretary’s rules. Tamper-resistant means built to stop people from changing the date, time, location, or duty-status records. The Secretary may use ELD data only to enforce safety and hours rules, must protect personal data, and should consider reducing paper record needs if ELD data replaces them. The Secretary must also keep rules to improve brake maintenance and inspections and set minimum training and qualifications for employees who work on brakes.
