Water covers a road and you cannot tell how deep it is or whether the pavement is intact. What should you do?
Correct answer: Turn around and use another safe route.
Do not drive into floodwater. Depth, current and washed-out pavement may be impossible to judge from the driver’s seat.

Snow or heavy rain makes traction uncertain. What should you do with cruise control?
Correct answer: Leave it off and manage speed yourself for the conditions.
The manual advises against cruise control in bad weather. Direct, smooth speed control is important when traction changes.

A snowplow ahead creates a cloud that hides the road and its equipment. What should you do?
Correct answer: Stay well back until you have clear visibility and a safe opportunity.
Snowplows have limited visibility and equipment wider than the visible vehicle. Do not drive into the snow cloud or attempt a shoulder pass.

Tall crops block your view of a rural intersection. You see no dust from another vehicle. What should you do?
Correct answer: Slow and approach cautiously; no dust does not prove the road is clear.
Vegetation and terrain can hide crossing traffic. The absence of a dust cloud is not reliable evidence that nobody is approaching.

Your car becomes disabled on the tracks, even though no train is visible. What is the first priority?
Correct answer: Get everyone out and well away from the tracks, then call the posted railroad emergency number or 911.
Move people away from the crossing immediately. The blue emergency notification sign provides a railroad phone number and crossing identifier; use 911 if that information is unavailable.

A vehicle ahead raises a heavy dust cloud on a dry gravel road. What should you do?
Correct answer: Slow down, increase the gap and use low-beam headlights.
Dust can hide the roadway and other traffic. The guide recommends low beams for visibility, a lower speed and a larger following gap rather than driving into the cloud closely behind another vehicle.

You approach a narrow rural bridge with little shoulder and an oncoming vehicle nearby. What should you be prepared to do?
Correct answer: Slow down and stop if needed to let the oncoming vehicle clear.
A narrow bridge may not leave enough room for simultaneous passage. The guide recommends slowing and being prepared to stop for oncoming traffic; do not assume there is a usable shoulder.

Ahead is a bridge with an open metal-grating surface. How should you adapt?
Correct answer: Reduce speed, hold the wheel firmly and increase the gap ahead.
Open grating or steel can reduce braking and steering traction. The guide advises lower speed, a firm steering grip and more following distance rather than aggressive corrections.
