Bad weather — Michigan Permit Test

In cold weather, bridges and underpasses freeze before the road does.

Cold air on all sides of a bridge freezes it while the road still looks wet.

In cold weather, bridges and underpasses freeze before the road does.

When it begins to rain, roads are most slippery during the first half hour, because oil from passing vehicles has not yet been washed away.

The first rain lifts oil off the pavement and makes it slick until more rain washes it off.

When it begins to rain, the roads are most slippery during the first half hour.

In rain, slow down and allow at least twice the normal following distance.

Wet pavement roughly doubles the distance you need to stop.

Slow down and allow at least twice the normal following distance.

Brakes may get wet after driving through deep water or heavy rain; test them by gently pushing the brake pedal until they work properly again.

Wet brakes may pull to one side or not hold at all until they dry.

Slow down and gently push on the brake pedal until the brakes work properly again.

When your tires ride on top of water on a wet road you are hydroplaning, which can cause loss of control; worn tires, low tire pressure or driving too fast contribute to it.

With water between the tires and the road, steering and braking stop working.

Worn tires, low tire pressure or driving too fast contribute to hydroplaning.

If a flooded road is blocked off by safety barricades, do not drive around them; there may be debris or power lines in the water, or the road may be washed away.

You cannot see what is under floodwater, and the road itself may be gone.

If a flooded road is blocked off by safety barricades, do not drive around them.

Drive slowly in fog with your low-beam headlights on, and be ready to stop quickly.

High beams reflect off fog and blind you; low beams light the road beneath it.

Turn on the low-beam headlights and be prepared to stop quickly.

If fog becomes so thick you cannot see at all, pull off the road, turn on your four-way flashers and wait for the fog to lift.

Driving blind is a crash waiting to happen; waiting it out is safer.

If fog becomes so thick that you cannot see at all, pull off the road. Turn on the four-way emergency flashers and wait for the fog to lift.

When driving in cold weather, listen for snowmobiles and watch for trail or crosswalk signs along the road, and be prepared to stop.

Snowmobile trails cross roads, and riders may appear suddenly.

In cold weather, be alert and listen for snowmobiles, watch for trail or crosswalk signs along the roadway and be prepared to stop.

Most skids happen when a driver tries to turn too quickly or stops suddenly on slippery pavement.

Sudden moves overpower the little grip a slippery road gives your tires.

Most skids happen when a driver tries to turn too quickly or stops suddenly on slippery pavement.

In cold weather, what freezes before the rest of the road?

Bridges and underpasses. Cold air on all sides of a bridge freezes it while the road still looks wet. What Every Driver Must Know, p.62: “In cold weather, bridges and underpasses freeze before the road does.”
