-
On packed snow, keep your speed constant.
-
On a wet road, use caution.
-
Allow extra time for stopping, because it takes longer and it will be harder to turn without skidding.
-
All of the above.
Correct Answer
A. Allow extra time for stopping, because it takes longer and it will be harder to turn without skidding.Explanation
When it is raining or snowing, it is important to adjust your speed by allowing extra time for stopping. This is because it takes longer to stop on slippery surfaces and it will be harder to turn without skidding. Keeping a constant speed on packed snow can be dangerous, as it increases the risk of losing control. Using caution on a wet road is also important, but it does not address the specific need for allowing extra time to stop and turn safely. Therefore, the correct answer is to allow extra time for stopping and turning without skidding.Rate this question:

Which of the following is true about double-clutching and shifting?
-
Use your tachometer and road speed to tell when you shift.
-
Double-clutch only on slippery roads.
-
If you miss a gear when upshifting, bring your vehicle to a stop.
-
Double-clutch only with a heavy load.
Correct Answer
A. Use your tachometer and road speed to tell when you shift.Explanation
Using your tachometer and road speed to tell when you shift is true about double-clutching and shifting. The tachometer measures the engine speed in revolutions per minute (RPM), while the road speed indicates the speed of the vehicle. By observing these two factors, a driver can determine the optimal timing for shifting gears, ensuring smooth and efficient transitions. This technique is particularly important in vehicles with manual transmissions, as it helps prevent engine damage and excessive wear on the clutch.Rate this question:

-
Quickly drive to the shoulder.
-
Countersteer.
-
Stay off the brake until the vehicle slows.
