Training keeps learning consistent for plow operators

Snowplow training

In snowy states, winter maintenance crews deal with everything from freezing rain and black ice to blizzards and even avalanches.

To prepare plow drivers for whatever Mother Nature has in store, state DOTs and other agencies kick off each winter season with training classes.

While all states provide some training for their winter maintenance crews, each program has different strengths and focus areas. Until recently, there was no standardized training curriculum addressing all aspects of a plow driver’s experience.

The Clear Roads winter maintenance research consortium ( set out to change that, sponsoring a project to develop a snowplow operator and supervisor training program that would cover all the bases.

The result: Twenty-two comprehensive training modules covering everything from avalanches to why salt won’t melt ice at 0°. The modules are available to any agency, including city and county highway departments, at no cost.

 “Clear Roads states needed a mechanism to allow everyone to have the same curriculum and training for snowplow operators,” said Michael Sproul, a winter maintenance engineer with the Wisconsin DOT. “With these training modules, now a snowplow operator from Wisconsin can have the same knowledge and training as one from Alaska or Ohio.”

Sproul and other Clear Roads members recognized the need for standardized training materials that would ensure all agencies have access to the same high-quality curriculum. They envisioned a training program that would provide training both for plow operators and for the supervisors responsible for overseeing winter maintenance operations, covering equipment, materials, techniques, procedures and advances in the field. The program needed to be both comprehensive and flexible: Easy for any agency to use, update and modify as needed.

To develop the snowplow training materials, Clear Roads contracted with a team of researchers led by staff at the University of Minnesota’s Center for Transportation Studies. The research team collaborated closely with the Clear Roads technical advisory committee to develop the 22 modules, which contain more than 1,300 presentation slides and provide over 42 hours of training materials.

To create the modules, the researchers first examined existing training programs for snowplow operators and supervisors, including courses from state DOTs and computer-based training modules offered by the American Association of State Highway & Transportation Officials.

Next, the researchers went straight to the source: Plow drivers and supervisors with decades of experience clearing snowy roads. Clear Roads committee members also contributed specialized knowledge; Colorado DOT’s David Wieder collaborated on the avalanche management module, while Cliff Spoonemore of the Wyoming DOT offered his expertise on drift control.

Each module in the Clear Roads training program contains two modes: one for operator training and one for supervisor training. The 22 modules can be used as a complete package or individually, and can be customized and edited. Most modules take 90 to 120 minutes to teach.

“The program is completely flexible to meet states’ needs,” explained Connie Fortin of Fortin Consulting, the modules’ lead author. “An instructor can use the materials to present short partial-day classes, or modules can be grouped into multiple-day trainings in a classroom setting.” 

Along with a PowerPoint presentation file, each module includes plenty of teaching aids, including an instructor’s guide with detailed directions, notes, resources, references and suggested activities, as well as skills tests for students. “The modules give very explicit instructions for the instructor,” said Project Coordinator Ann Johnson, a teaching specialist with the University of Minnesota. “Even the most novice presenter will be able to teach these modules.”

The “Science of Freeze Point Depressants” module includes videos as well—a key feature for some agencies. At the Pennsylvania DOT, staff have incorporated the modules’ videos, presentations and skills tests into the department’s existing winter operator training materials. “Having quality-edited videos in our winter operator training enhances our ability to convey snow-removal techniques and ideas to our operators,” said Jon Fleming, chief of Pennsylvania DOT’s Maintenance Technical Leadership Division. “The videos help us get across ideas that may be missed with text-only PowerPoint presentations.”

Training modules on the practical aspects of winter maintenance operations such as plow operation, prewetting techniques, anti-icing tactics and understanding ice formation can aid all operators.

Following procedures

The training modules cover several broad areas:

  • Equipment and materials;
  • Principles of weather and ice;
  • Safety;
  • Environmental concerns; and
  • Winter maintenance management.

The “Plowing Procedures” module covers snowplowing in great detail, from basic to complex procedures. The module includes guidance for one- and two-person plowing operations and various plow configurations (nose plows, reversible and one-way plows, right wing only, left wing only, double wing and underbody plows); information on echelon/gang plowing and tandem plowing techniques and strategies; recommendations for plow speeds and actions in white-out conditions; and plowing tips from experienced drivers.

The other two modules covering equipment—trucks and spreaders (including controllers and calibration)—are just as thorough. Five modules on materials usage cover deicing materials and how to use them most effectively, as well as prewetting, brine production and anti-icing.

Training modules on practical science address topics such as ice formation, freezing point depression, bridge frost and deicers in the environment. “Principles of Ice Formation” examines the mechanism of traffic compaction, and describes the creation of snow-packed ice, black ice, snow glaze, blow ice and freezing rain—forms of hazardous road ice that scare so many winter drivers the most. “Science of Freeze Point Depressants” makes clear why sodium chloride alone does not work well as a deicer below 15°. “Weather Basics” delves into the science of forecasting, tracking and winter maintenance decision-making.

Speaking to growing concern about the harmful environmental effects of excessive chloride retention and transport in watersheds, “Snow/Ice Control Agents and the Environment” focuses on the effects of chlorides, organics and abrasives that escape the roadway and migrate into the soil and groundwater.

The essential responsibilities and tasks “off the plow” that agency personnel must address are covered in modules focusing on safety, materials management and policies, levels of service, record-keeping, preparing for winter operations, and winter maintenance for supervisors.

The program fills a clear need. “This training program provides a base of knowledge that anyone who plows the roads should have,” Fortin said. “The modules make it easier for states to provide current information for their employees.”

Plow operators can be trained on various plow configurations, including nose plows, reversibles, single wing, double wing and underbody plows.

Adding muscle to training

The training modules have done just that at the Michigan DOT, which recently revised a portion of its winter operations course for new employees. “We wanted to beef up the portion of the course on material use,” said Region Support Engineer Melissa Longworth. “The training module on material use was an easy-to-use addition. It saved us a lot of time.”

Staff at the Oregon DOT have modified select presentation slides to add agency-specific policies and have branded them with the ODOT logo. “We’ve used multiple slides from the various modules to enhance our own internal training,” said Patti Caswell, ODOT’s Maintenance Environmental Manager. “We’ve made the modules available to our field offices and suggested they pick one or two to review at their monthly crew safety meetings.”

The Clear Roads training materials are a boon to local agencies that may not have the resources to develop their own in-house training programs from scratch. And the modules have been a time-saver for larger agencies as well.

“Previously, our training staff had to gather training information from multiple sources, which is time-consuming and can lead to conflicting information,” said Allen Williams, maintenance engineer in the Virginia DOT’s Salem District. “With the new Clear Roads training modules, trainers will be able to spend more time training instead of doing research and developing the training format and classroom materials.”

Brian Burne, a highway maintenance engineer with the Maine DOT, agreed. “Our Local Technical Assistance Program director is planning to use the modules to help local agencies establish their own programs,” Burne said. “We’re also using the modules to improve our own annual fall training.”

Todd Miller, maintenance liaison engineer at the Missouri DOT, reiterated the importance of having a high-quality training program for snowplow operators.

“The last two winters have been mild here in Missouri,” Miller said. “Pair that with a high turnover rate, and training for inexperienced operators is critical. MoDOT will use much of the information in these modules in our ‘Gear Up’ introductory snowplow training, and we plan to review the modules to see where we might add them into our lineup to enhance our winter operations training efforts in the off-season.”

 Clear Roads is encouraging users to provide feedback as they present the modules, and the group plans to update the training materials periodically to reflect the latest innovations and best practices.
