Special Driving Conditions Training Flashcards

Which skill should a CDT instructor assess FIRST when evaluating a student's readiness for driving in reduced-visibility conditions?

Answer: Proper adjustment of mirrors and use of all lighting controls

Proper mirror adjustment and correct use of vehicle lighting are foundational skills that must be verified before any reduced-visibility driving begins.

A student asks whether it is safe to use cruise control on a wet highway. The correct instructor response is:

Answer: No, because cruise control prevents the driver from feeling road surface changes and can worsen aquaplaning

Cruise control can cause the vehicle to accelerate when tires lose contact with the road during aquaplaning, making it unsafe to use in wet conditions.

During winter driving instruction, what is the primary reason CDT programs recommend starting from a stop on snow using gentle throttle application?

Answer: To avoid wheel spin that reduces traction and can cause loss of control

Gentle throttle prevents the driven wheels from spinning faster than the vehicle moves, which eliminates tire traction and makes steering control impossible.

A CDT instructor observes a student applying brakes while still in a curve on a slippery road. Why is this dangerous?

Answer: Braking shifts weight forward, reducing rear tire grip needed for cornering, risking a spin

Braking transfers vehicle weight to the front tires, reducing rear traction below what is needed to maintain the curved path and triggering oversteer or understeer.

When training a student to drive through standing water on a city street, which post-crossing check should instructors require?

Answer: Lightly applying the brakes several times to dry and test brake effectiveness

Water can temporarily reduce brake pad friction, so light brake applications after passing through standing water restore and verify brake effectiveness.

A student driving in a snowstorm feels the rear of the vehicle begin to slide outward on a straight road. Which response should the instructor teach?

Answer: Release the accelerator and steer in the direction the rear is sliding

Steering into a rear-wheel slide (opposite lock) and easing off the throttle allows the rear tires to regain traction and realign the vehicle.

Which instructor action BEST demonstrates the effect of reduced reaction time in night driving to a CDT student?

Answer: Having the student read road signs from a greater distance in daylight vs. darkness

Comparing the student's ability to identify and read road signs at the same distance in daylight versus darkness demonstrates the concrete reduction in detection range at night.
