CLP Managing Space and Speed 3

Question 1

When merging onto a highway, a CMV driver should:

Accepted Answer

Match the speed of highway traffic before merging

Answer

Matching highway traffic speed before merging reduces the speed differential and minimizes the risk of a rear-end collision.

Question 2

How does cargo weight affect the speed at which a CMV should take a turn?

Accepted Answer

Heavier or high cargo raises rollover risk, requiring slower turns

Answer

A higher or heavier load raises the center of gravity, making a CMV more prone to rollover when turning, so speed must be reduced.

Question 3

You are driving in heavy rain and notice your CMV is hydroplaning. What should you do?

Accepted Answer

Ease off the accelerator and steer straight until tires grip again

Answer

During hydroplaning, easing off the throttle and holding a straight path allows tires to re-contact the pavement without causing a skid.

Question 4

What is the safest speed to travel in a construction zone as a CMV driver?

Accepted Answer

The posted construction zone speed limit or slower if conditions require

Answer

CMV drivers must obey posted construction zone speed limits and reduce speed further if workers, narrow lanes, or other hazards are present.

Question 5

On a two-lane road, a CMV driver approaches a crest hill and cannot see oncoming traffic. The driver should:

Accepted Answer

Move to the right side of the lane and reduce speed

Answer

Keeping to the right and reducing speed at blind crests gives more reaction time if an oncoming vehicle appears suddenly.
