Winter weather poses unique challenges for professional drivers across the U.S. and Canada. From
freezing rain and black ice to whiteouts and unpredictable temperature swings, conditions can shift
rapidly, and so can the risk level. Fleet drivers who anticipate these hazards and adjust their driving
behavior play a critical role in preventing incidents and keeping operations moving safely.

Southern and Coastal Fleets

In the southern and coastal regions, winter weather often means fluctuating temperatures, fog, and
occasional freezing rain. These conditions are less predictable and can catch even experienced drivers off
guard.

What fleet drivers should remember:

• Monitor the weather before every route. A cold morning after overnight rain can produce black
  ice or dense fog.

• Adjust speed and space. Even a drizzle can double the stopping distance. Maintain a minimum six-second following distance in wet conditions.

• Avoid driving when ice is reported. There is no safe technique for operating on ice, and a delay
  departure until conditions improve.

• Stay alert for seasonal visitors. Southern regions see an influx of “snowbirds” unfamiliar with
  local roads and traffic patterns. Keep extra space and anticipate erratic moves.

Western and Mountain Operations

Drivers covering western routes often face a dramatic range of weather conditions within a single shift.
Rain at lower elevations can quickly become snow or sleet as altitude increases.

Safe practices include:

• Check forecasts across your route, not just at your origin. Use fleet apps or dispatch notifications
  for real-time updates.

• Be aware of chain laws. Many states and provinces, including Colorado and British Columbia,
  require tire chains under specific conditions.

• Slow before entering overpasses and shaded curves. These surfaces freeze before main roadways.

• Increase following distance. Use the 6-second rule in rain and 12-second rule in snow to maintain
  adequate stopping room.

• Fully clear your vehicle. Snow or ice falling from a company vehicle creates danger and potential liability.

Midwestern Fleets

The Midwest’s sub-freezing temperatures make black ice a constant risk. Fog and light snow also
contribute to reduced visibility and surface traction.

Guidelines for safer driving:

• Expect black ice where the road looks wet. Keep your steering straight and ease off the gas until traction returns.

• Approach intersections and ramps slowly. These are high-risk areas for refreezing and loss of
  control.

• Plan for slower travel. Dispatchers and fleet managers should factor in longer route times during the winter months.

Northern U.S. and Canada

Fleet drivers operating in northern climates face the most challenging conditions: extreme cold, heavy snow, and low visibility.

The U.S. Federal Highway Administration reports that nearly one in four weather-related crashes occurs
on snowy, slushy, or icy pavement. Transport Canada adds that roughly 30% of all collisions happen on
winter roads.

Preparation is critical:

• Perform a pre-trip inspection every day. Verify tire tread, brakes, and fluid levels.

• Clear all snow and ice. Many Canadian provinces have “clear roof” laws requiring drivers to
  remove all snow before travel.

• Drive smoothly. Gentle acceleration, braking, and steering prevent skids and loss of control.

• Use sunglasses. Snow glare increases fatigue and reduces visibility.

• Keep your fuel tank at least half full. This prevents freeze-ups and provides heat if stranded.

• Carry a full emergency kit: thermal blanket, traction aids, food, water, flashlight, and portable
  charger. 

Technology and Equipment

Modern fleet vehicles often include features such as four-wheel drive (4WD), all-wheel drive (AWD),
and electronic stability control (ESC).

While these systems support traction and stability, they do not eliminate the need for safe speeds or
extended stopping distances.

Even with advanced vehicle systems, physics still applies; tires have limited grip on ice.

Additional reminders:

• Avoid over-reliance on technology. ESC helps correct a skid, but it cannot overcome excessive
  speed.

• Telematics can support coaching. Use performance data to identify safe driving habits, not to
  penalize drivers during winter operations.

• Keep tire pressure checked. Cold temperatures reduce air pressure, affecting handling and
  braking.

Winter EV Fleet Considerations

Modern electric vehicles (EVs) present some unique winter-driving and fleet-management considerations.
Cold ambient temperatures slow the chemical reactions inside a lithium-ion battery, reducing its ability to
deliver power and accept a fast charge. One study found that in freezing temperatures, most EV models
averaged only ~80 % of their range compared to ideal conditions.

Pre-conditioning the Battery and Cabin

Pre-conditioning—warming up both the cabin and the high-voltage battery while the vehicle is plugged in—significantly improves winter performance. By using grid power to bring the battery and cabin to optimal
temperature before departure (or before a fast-charging session), the vehicle preserves more of its usable
range and avoids slower charging rates.

Charging strategy in cold weather

Cold weather not only reduces range but also slows charging. EVs in extreme cold may take significantly
longer to accept a charge or may reduce the charging rate until the battery is warmed Fleet drivers should
adjust by:

• Keeping the vehicle plugged in whenever possible so it can maintain thermal balance and be
  ready for departure.

• Charging to a higher state of charge in winter (for example, 80-100 % instead of typical 80 %) if
  needed for longer routes or less predictable conditions.

• Scheduling pre-conditioning before arriving at a fast charger to maximize charging rate and
  minimize time lost.

Operational impact for fleets

For fleet operations managing EVs, this means creating protocols around pre-conditioning (via telematics
triggers or driver app prompts), incorporating higher buffer charge levels in winter, and accounting for
longer route times (range loss, slower charging) in winter scheduling. Fleet vehicles parked overnight in
cold zones should ideally remain plugged in, and departure schedules should allow time for preconditioning rather than launching cold. Moreover, drivers should be trained to use lower-energy cabin heating options (such as seat- and steering-wheel heaters) rather than full-cabin HVAC when range is critical.

If You Skid

• Stay calm and avoid braking.

• Steer gently in the direction you want the vehicle to go.

• Ease off the accelerator until traction returns.

• Once the vehicle stabilizes, apply gentle throttle to regain control.

If the vehicle becomes stuck:

• Call dispatch and provide your exact location.

• Check that the exhaust pipe is clear before running the engine.

• Stay with the vehicle unless visibility is clear and conditions are safe to leave.

Fleet Readiness Before Winter

Fleet managers can strengthen safety culture before the first snowflake falls by:

• Scheduling winter prep inspections (battery, tires, fluids, wipers).

• Issuing cold-weather emergency kits for each vehicle.

• Providing refresher training focused on space management, braking techniques, and skid
  recovery. 

• Establishing communication procedures for drivers encountering unsafe conditions.
  Winter driving demands professionalism, patience, and preparation. Every driver’s decision to slow down, increase following distance, and anticipate hazards contributes to fewer crashes, lower claim costs, and safer communities.

Safety isn’t seasonal; it’s a year-round commitment that starts behind the wheel.
