The Road Commission for Oakland County is getting ready for the inevitable arrival of winter weather and hiring workers to augment snowplow drivers.

The Road Commission says it’s in the process of reviewing its winter operations with its truck drivers, and mechanics are preparing its winter-maintenance equipment including trucks and plows in anticipation of the upcoming season.

Again this winter; both full-time, permanent laborer/truck drivers and temporary (part-time) laborers/drivers are being hired to augment winter operations. Visit the “Careers” section of the RCOC website for more details. That link is provided.

RCOC is also continuing to update its fleet of snowplows/salt trucks and is currently in the process of adding 34 new plow trucks, which cost approximately $425,000 apiece.

RCOC Managing Director Dennis Kolar said “We are continuing to replace our aging fleet of trucks. As a safety feature, all new trucks are equipped with green lights that can be seen from a greater distance during winter weather. Pick-up trucks used for winter maintenance are also equipped with the green lights.”

Kolar noted the agency is prepared for whatever Mother Nature brings during the winter, though a milder winter is always appreciated. He said “Winter maintenance is one of our most critical functions for the safety of everyone. We always prepare for a worse-than-normal winter which includes having plenty of road salt available.”

The RCOC team says it is also constantly looking for best practices when it comes to maintaining roads during the winter months, such as the “wing plows” ordered with new trucks in recent years. The wing plows extend from the right side of the truck and are retracted when not in use.

Kolar said “The wing plows increase the width of roadway plowed by a single truck, enabling trucks to plow a roadway lane and the shoulder at the same time, for example. Equipping many of our trucks with wing plows has improved their efficiency”.

RCOC also utilizes its pickup fleet to clear crossovers/turnarounds on boulevards in a more timely manner as well as to get into subdivisions/residential streets more quickly. The pickup fleet is also used for winter-weather rapid-response operations that allow RCOC staff to get to isolated icing occurrences and other urgent situations more quickly.

Additionally, during or following weather events with six or more inches of snow, RCOC uses non-road-maintenance staff to augment its pool of drivers and hires contractors to help on gravel roads.

Despite the addition of the part-time, temporary employees and the rapid-response plan, Kolar explained that motorists must still be vigilant when driving during or immediately after snow events. He reminded “Drive for the conditions. That will make a safer environment for everyone on the road”.

Kolar also reminded motorists that as of last year, Michigan law requires motorists to stay 200 feet back from a plow truck to help ensure the safety of motorists. Kolar said “It can take a longer distance to stop in snow and ice, and when vehicles run into the back of one of the big orange trucks, it’s not good for the passenger vehicle. So, please don’t crowd the plow -- give the plows ‘room to groom’.”



A fact sheet about RCOC Winter Maintenance operations is provided below.

RCOC Winter Maintenance Fact Sheet 2025-2026

Below are some facts and figures related to winter road maintenance in Oakland County.

• Salt trucks and snowplows typically travel more slowly than other traffic. RCOC urges drivers to use caution around the orange trucks and allow them enough room to safely do their jobs: “Don’t crowd the plow.”

• RCOC uses an average of 64,000 tons of salt per winter.

• RCOC salt trucks are kept at six garages located throughout the county. Salt is kept in salt storage facilities at each of those garages. Those facilities, currently nearly full, together hold a total of about 37,500 tons of salt.

• In all, RCOC has jurisdiction over 2,700-plus miles of county roads (including subdivision and gravel roads).

• RCOC also maintains 230 miles of mostly multi-lane state highways on behalf of the Michigan Department of Transportation (MDOT). This includes I-75, I-696, I-96, M-59, Telegraph Road and Woodward Ave., among others. These 230 miles of mainly freeway roads are the equivalent of 1,500-plus miles of one-lane pavement.

• RCOC divides all the miles of paved primary roadway it maintains (including county roads and state highways) into 109 “salt routes.” A single “salt run” for a truck typically uses about six tons of salt and takes about two hours.

• RCOC spends approximately $12 million on winter road maintenance over the course of a winter, including approximately $5.2 million to maintain the state highways for MDOT.

• RCOC will spend $57.78 per ton for salt this year, up from the price of $55.29 paid last year.

• It can cost RCOC more than $43,000 per hour to operate at “full-run coverage” (trucks out on all 109 salt runs) during overtime situations.

• RCOC standards call for approximately 400 pounds of salt to be applied to each two-lane mile of pavement.

• All RCOC salt trucks are equipped with computerized salting mechanisms that automatically adjust the amount of salt spread based on the vehicle’s speed. The salt spreaders also include “pre-wetting” devices that spray salt brine on the salt as it is being spread to prevent the salt from being scattered off the road and to activate the melting process more quickly. These technologies also allow RCOC to conserve salt.

• At temperatures below 20 degrees, salt begins to lose its effectiveness. At 10 degrees, it does virtually nothing.

• Salt is still the most cost-effective option for removing snow and ice and maintaining the safest roads possible.

• RCOC keeps salt trucks ready to go 24 hours a day, seven days a week, and has a rapid-response team ready to go on short notice.

• RCOC crews maintain state and county roads in Oakland County based on a priority system. “Critical priority” roads are those with more than 10,000 vehicles per day per lane. “Priority 1” roads are those with 2,500 to 10,000 vehicles per day per lane, while priority 2 and 3 roads have less traffic. Priorities can be found on the website: http://www.rcocweb.org/160/Snow-Plowing

• RCOC typically does not use sand on paved roads because it does not melt ice and can clog storm drains. Sand is used on gravel roads for traction and where typically there are no storm drains and where salt is ineffective.

• A single RCOC snowplow/salt truck costs approximately $425,000 new, a nearly 200 percent cost increase over the last 10 years. The cost for snowplow blades necessary for winter snow and ice removal has risen 100 percent since 2004.

• RCOC has approx. 147 snowplows/salt trucks, though all trucks are never used at the same time (some are “spares,” used when others break down). RCOC also employs 19 “road graders” that are used to plow heavy snow.

• Fully loaded, RCOC snowplows get about 4 miles per gallon of fuel. Empty, they get about 6 miles per gallon.

• RCOC contracts with a number of Oakland County communities to salt and plow some RCOC roads within their boundaries when those communities choose to provide a higher level of service for their residents.
