29 . An applicant may label parts of the vehicle that will be covered in the pre-trip inspection.
When taking the pre-trip inspection test, you may not have labels placed on parts of the vehicle to help you remember which parts need to be inspected or their weight in scoring. Labels placed by the manufacturer are acceptable as long as they are not excessive.
30 . After a trip:
A vehicle's battery should be disconnected.
After a trip, you may be required to perform an inspection and file a report on each vehicle that you've driven.
31 . A thin layer of ice that forms on road surfaces is called:
Blue ice.
Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet. You should be very careful when temperatures are below freezing and the road looks wet.
32 . Noting the speed of other vehicles is one way to determine when to upshift.
There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.
33 . To help your vehicle be seen by others:
Your headlights should be used, but only in the rain.
A vehicle's headlights should be clean during trips. This will ensure that the lights can provide as much light as possible, helping the vehicle to be seen.
34 . If you are being tailgated, you should:
Allow the vehicle to pass.
If you are being tailgated, it is advisable to open up the space in front of your vehicle, making it easier for the tailgater to get around you. Speeding up may be counterproductive because the driver may continue to tailgate you at the higher speed, only increasing the danger.
35 . In a leaf spring:
When inspecting your vehicle's suspension, verify that leaf springs do not have missing or broken leaves. If at least one-fourth of the leaves in a leaf spring are missing, the vehicle will be put out-of-service until the defect is fixed.
