43 . Convex mirrors:
Are illegal in most states.
Convex mirrors are curved to provide drivers with wider views of the road than can be provided by flat mirrors. However, convex mirrors also make objects appear to be smaller and farther away than they really are.
44 . To stop in a vehicle that uses air brakes, the driver should:
Pull the brake pedal up.
To make a normal stop in a vehicle with air brakes, push the brake pedal down. The harder the pedal is pressed, the more air pressure is released.
45 . To check the automatic transmission fluid level in some vehicles, the vehicle:
May have to be left running.
For some vehicles, you may need to leave the engine running to be able to check its automatic transmission fluid level.
46 . When testing a parking brake, the vehicle should:
Be driven while the parking brake is applied.
To test a parking brake, you should fasten your safety belt, set the parking brake for the power unit, release the trailer parking brake (if applicable), place the vehicle in low gear, and attempt to pull forward against the parking brake. If the parking brake does not hold while you are attempting to pull forward against it, the brake is faulty and must be fixed.
47 . If you are being tailgated, you should:
Allow the vehicle to pass.
If you are being tailgated, it is best to allow more room to open up in front of your vehicle. This will help you avoid the need for sudden stops, which could result in the tailgater rear-ending you, and will make it easier for the tailgater to pass. Speeding up may only make things more dangerous by prompting the other driver to continue tailgating you at a higher speed.
48 . You may be denied a HazMat endorsement if:
You do not suffer from a mental illness.
You will be denied a HazMat endorsement, or lose an existing endorsement, if you are not a lawful permanent U.S. resident; you renounce your U.S. citizenship; you are wanted for, under indictment for, or convicted of certain felonies; you are judged as mentally unstable or are committed to a mental institution; or you are deemed to pose a security threat by the Transportation Security Administration (TSA).
49 . How much water must be on a road surface for a vehicle to hydroplane?
None
Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be much water on the road for this to occur.
50 . If a truck's Anti-Lock Braking System (ABS) is not working:
The truck will lack brakes on its left side.
If an ABS system fails, the vehicle will still have normal braking function. The driver should continue to drive and brake as they normally would.
