Winter driving — Missouri Permit Test

In winter, clean all snow and ice off your windows, headlights, and taillights, and never start driving until all of it is off your windows.

A patch scraped clear at eye level is not the same as a clean window, and the rest of it is where the cyclist is.

If there is snow or ice on the road, slow down and do not use your vehicle's cruise control system.

Cruise control keeps the power on when a wheel slips, which is exactly the wrong response.

If there is snow or ice on the road, slow down and do not use your vehicle’s cruise control system.

Leave about eight to ten seconds between your vehicle and any vehicle ahead when driving on snow or ice.

Three seconds is for dry pavement. On ice you need three times as much, because the brakes do far less.

be sure to leave a safe distance, about eight to ten seconds, between your vehicle and any vehicle ahead of you

Apply the brakes gently and smoothly on snow or ice, and never slam them on, because that may cause a skid.

A locked wheel does not steer and does not slow you much either.

When you want to slow down or stop, apply the brakes gently and smoothly. Never slam on your brakes — this may cause you to skid.

On very slippery surfaces, pump the brakes by gently pushing down and letting up on them several times.

Pumping keeps the wheels turning, and a turning wheel is the only one that steers.

On very slippery surfaces, pump the brakes by gently pushing down and letting up on them several times.

Bridges and overpasses freeze and become slippery before other parts of the road.

Cold air passes under a bridge as well as over it, so it loses heat from both sides.

Remember that bridges and overpasses will freeze and become slippery before other parts of the road

If you have a four-wheel drive vehicle, do not use four-wheel drive on ice, because four-wheel drive vehicles can easily overturn on it.

Four driven wheels help you start moving. They do not help you stop or turn, and they raise the speed you arrive at trouble.

If you have a four-wheel drive vehicle, do not use the four-wheel drive on ice.

If you hit an icy patch while in four-wheel drive, take your foot off the accelerator.

Taking the power off is the only correction that does not ask the tires for grip they do not have.

If you hit an icy patch in four-wheel drive, take your foot off the accelerator.

If your tires start to spin on snow or ice, try clearing a path by driving backwards and forwards a few times.

Rocking the car packs the snow into something the tire can push against.

If your tires start to spin, try clearing a path by driving backwards and forwards a few times.

Never let anyone stand in line with your wheels when you are trying to free a stuck vehicle, because the wheels may throw up gravel or ice.

A spinning wheel throws whatever is under it backwards at speed.

NEVER let anyone stand in line with your wheels.

Once you have started on snow or ice, gently brake while driving to see how slippery the road is, and then adjust your speed.

A gentle test tells you what the road will do before you have to find out at speed.

Gently brake while driving to see how slippery the road is and then adjust your speed for the road conditions.

What must be cleared before driving in winter?

All snow and ice from the windows, headlights, and taillights. A patch scraped clear at eye level is not the same as a clean window, and the rest of it is where the cyclist is. Missouri Driver Guide, p.62: “In winter, clean all snow and ice off your windows, headlights, and taillights.”
