Arkansas Commercial Driver License (CDL) Practice Test

What should you consider when selecting a safe speed for driving down a steep grade?

Road conditions, total weight, length of grade, steepness Time of day, number of passengers, air temperature Traffic density, fuel levels Radio station, air conditioning settings

Correct Answer:

Road conditions, total weight, length of grade, steepness

Explanation:

When driving down a steep grade, it's important to consider factors that could impact your vehicle's performance and control. The other options do not affect your vehicle's performance and control, making them incorrect choices. While time of day and air temperature may impact comfort and visibility, they do not directly relate to the proper speed for navigating a steep grade. Similarly, traffic density and fuel levels may influence the flow of traffic and the need for refueling, but they do not impact the safe speed for driving down a steep grade. Therefore, A is the most important factor to consider when selecting a safe speed for driving down a steep grade.
