By what date must all drivers required to complete paper logs switch to using ELDs?

Answer: B — December 16, 2017

The correct answer indicates that December 16, 2017, was the compliance date for drivers required to switch from paper logs to electronic logging devices (ELDs). This transition was mandated by the Federal Motor Carrier Safety Administration (FMCSA) to improve road safety and ensure more accurate tracking of driving hours. By this date, drivers who were already using paper logs had to have adopted ELDs in order to meet the federal requirements. The implementation of ELDs was a significant step toward enhancing compliance with hours-of-service regulations, which help prevent driver fatigue and increase overall safety on the road. Understanding this timeline is crucial for drivers and carriers to maintain compliance and avoid potential penalties associated with failure to adopt ELDs by the designated deadline.
