Drivers may not drive more than _______ hours following an eight-hour break.

  1. 6

  2. 10

  3. 13

  4. 16

The correct answer is: 13

The correct answer is based on regulations concerning driving hours for commercial motor vehicle operators in Ontario. After an eight-hour break, drivers are permitted to drive for up to 13 hours. This regulation is in place to ensure that drivers are not on the road for excessive periods without adequate rest, which can lead to fatigue and increase the risk of accidents. Understanding the importance of managing driving hours is critical for safety on the road. It helps in reducing the chance of drowsiness while driving and promotes better overall health for drivers by ensuring they take essential breaks. The other durations listed are not in line with the regulations. A 6-hour limit would not ensure that drivers can adequately cover the required routes, while 10 and 16 hours exceed safe operational limits post-break. The use of 13 hours balances necessary driving time while still prioritizing safety and compliance with driver regulations.
