8 . Texting while driving is worrisome:
Because it is less efficient than a phone call.
When driving, texting is a particularly dangerous distraction because it distracts a driver both mentally and physically.
9 . When traveling down a long downgrade, you should brake by:
Never using the brakes.
On a downgrade, you should use the braking effect of your engine as the principal way of controlling your speed. Save your brakes for additional slowing or stopping that may be required by road or traffic conditions.
10 . How should you brake if your vehicle loses its ABS?
Avoid using the brakes.
An Anti-Lock Braking System (ABS) is in place as an addition to a braking system. It intervenes to prevent brakes from locking up during hard braking. If ABS is not working, the basic braking functions on a vehicle will still remain, so the driver can continue to drive and brake normally.
11 . After a vehicle is started, the engine oil pressure should come up to normal:
After five minutes.
After a vehicle's engine is started, the engine's oil pressure should rise to its normal level within seconds. Do not drive a vehicle with oil pressure that is too low.
12 . The controlled braking method is:
When the driver downshifts the gears to brake.
The method of controlled braking involves applying the brakes as hard as you can without locking the wheels. If you need to make large steering adjustments while using controlled braking, you should remove your foot from the brake pedal, steer, then reapply the brakes.
13 . If you are experiencing an engine fire, you should:
Turn on the heater.
In the event of an engine fire, you should turn off the engine as soon as possible. Do not open the hood unless absolutely necessary. Using a fire extinguisher, shoot foam through the louvers or radiator, or from the vehicle’s underside. If you are unsure of how to treat a fire, wait for firefighters to arrive.
14 . If you are turning left where there are two available turning lanes:
You should use both lanes.
If making a left turn where there is more than one available turn lane, you should always choose to take the rightmost lane. Large vehicles often have to swing right to make left turns, so it is safer for you to have other left-turning traffic to your left. This will allow you to have the best possible view of other turning vehicles and will lower the risk of your vehicle colliding with them.
