Winter Driving Manitoba Flashcards

What is a block heater and why is it essential in Manitoba?

Answer: An electric heater that keeps the engine block warm overnight, ensuring reliable cold starts and faster warm-up

A block heater keeps the engine coolant warm when the vehicle is parked, making cold starts much easier and reducing engine wear. In Manitoba's extreme cold (-30°C to -40°C), a block heater is practically essential for reliable starting.

When driving behind a snowplow on a Manitoba highway, what is the safest course of action?

Answer: Stay well behind the snowplow — the road ahead of it is worse than the road behind it

The road behind a snowplow is clearer than the road ahead of it. Stay well back to avoid the snow spray and debris. If you pass, you will be driving on unplowed or untreated road, which is more dangerous.

In Manitoba winter driving, what is the 'threshold braking' technique?

Answer: Applying brake pressure to the maximum point just before the wheels lock up, for maximum stopping power

Threshold braking means applying brake pressure up to the point just before wheel lock-up. This provides maximum braking force while maintaining steering control. In vehicles without ABS, this technique is essential on slippery surfaces.

What should you do if your vehicle starts to fishtail on an icy Manitoba road?

Answer: Ease off the gas, do not brake, and steer gently in the direction the rear is sliding (into the skid)

Fishtailing occurs when the rear tires lose traction. Ease off the accelerator and steer gently in the direction the rear end is sliding. This is called 'steering into the skid.' Avoid braking, which can worsen the slide.

Why are Manitoba winter roads particularly dangerous at dusk and dawn?

Answer: Melting during the day can refreeze at dusk, and early morning frost creates icy surfaces — visibility is also reduced

At dusk, daytime melting refreezes as temperatures drop, creating icy patches. At dawn, frost and black ice are common. Both periods also have reduced visibility from low sun angle, glare, and reduced daylight.

What is the recommended practice for using cruise control on winter Manitoba roads?

Answer: Do not use cruise control on icy or snow-covered roads — it can cause loss of control

Never use cruise control on icy, snowy, or wet roads. Cruise control may apply power when the wheels lose traction, causing a spin. You need direct throttle control to respond to changing surface conditions.
