Q. A few days ago my family was awakened at 4:40 a.m. by a snowplow clearing our street. While it’s nice of the city to get the streets clear in time for people’s morning commute, it made me curious about the safety of the snowplow drivers. So, my question is: Could you tell me how the city ensures that the snowplow drivers are able to get enough sleep?

A. “We limit our employees to 12 hours of driving in a commercial (plowing, etc.) driving capacity in a 24-hour period,” emails city communications specialist Robert Kellar. “Supervisors are also trained to look for signs of fatigue and will send drivers home or assign them to another task if there is any question about their ability to drive.”
